Tech events in barcelona

The full-stack Java conference Vaadin runs in Barcelona: two days at Hotel Catalonia Barcelona Plaza on Plaça d'Espanya, from 09:00 on 27 October through to 16:00 on 28 October. The framing is the pressure full-stack teams are under — AI writing more code, legacy systems still needing to reach the web, and applications that have to be secure, accessible and long-lived. Sessions span the wider Java ecosystem rather than just Vaadin: Jakarta EE, Spring Boot and Kotlin, with tracks on AI-assisted development, enterprise UI and modernisation. The organisers state you do not need to know Vaadin to attend. Standard tickets are 999 euros excluding 21% Spanish VAT; the 799 euro early bird closed on 31 March. Registration goes through Eventbrite. Why go: two days of people maintaining real enterprise Java web applications, which is a thinner conference circuit than it should be. Best for senior Java developers and architects weighing a modernisation.

with Isabela Fernandes (Executive Director, Tor Project) · Kay Coghill (Head of Community, BlackSky Algorithms) · Valentina Aguana Villegas (Mozilla Fellow, Conexión Segura y Libre) + 5 more

The privacy-tech fringe to Mozilla Festival, held the evening before the festival opens and in the same Sant Andreu neighbourhood. The speaker list is the reason to pay attention. Isabela Fernandes, Executive Director of the Tor Project, is on it, alongside Kay Coghill of BlackSky Algorithms, Mozilla Fellow Valentina Aguana Villegas on digital security for activists, Julian Mair of Phoenix R&D on the in-house MLS encryption behind Air messaging, Jordi Pinyana of Vocdoni on the Catalan-built private voting protocol that has processed 200,000 votes across unions and co-ops, Tessa Brown of Germ Network and Prague hacklab co-founder Mario Havel. Talks, circles, panels and debates, 17:00 to 21:00, free. La Cinetika is a self-managed squatted cinema on Rambla de Fabra i Puig; the entrance is on Carrer de les Monges. Why go: a room where people actually shipping privacy infrastructure compare notes with the activists using it. Best for cryptography and protocol engineers, and anyone working on surveillance policy.

with Bruno Romão Antunes (Organiser, Barcelona JUG) · Anyul Led Rivas (Organiser, Barcelona JUG)

A three-hour competitive hackathon run by Barcelona's Java User Group at AI Campus Barcelona. You build an application that registers a squad of superheroes into a live tournament API, and the organisers run the battles. Teams form on arrival, then there is an introduction to the Arena API before the rounds start. Each round adds constraints such as squad limits or budget caps, and results stream live as the bracket advances. Any language or framework is allowed, a Java starter template is provided, and the API spec and docs are published in advance at superhero-battle-arena.barcelonajug.org so you can plan before you turn up. Vonage sponsors the prizes: a Keychron keyboard, an MX Master 3S and a gaming headset for the top three. Free, 18:00 to 21:00, RSVP on Meetup. Why go: a build-and-compete evening rather than slides, and explicitly open to students and junior developers. Best if you want a low-stakes way to ship something in three hours alongside other people.

An evening with the Mozilla community the night before MozFest opens across town. Mozilla staff, long-time contributors, Firefox users and open source regulars meet at La Fabrica &Co in Sant Martí for Firefox lightning talks and a practical look at how to start contributing. The agenda is tight: check-in at 18:00, lightning talks and presentations from 18:15, drinks and light bites from 19:15, a prize raffle and close at 19:50. The hosts are Mozilla people — Pascal Chevrel, Konstantina Papadea, Eduardo Feo, Andres Furlan, Nishant Bhasin and Issam Mani. Free, capacity capped, and already full at 74 going, so registration is a waiting list. Why go: it is the one Barcelona room this year where Firefox engineers and contributors are together off-stage, and the easiest place to find out what contributing to Mozilla actually involves.

with Victor Martín (Principal DevOps Consultant, ERNI) · Enric Font (DevOps Engineer, Adevinta)

The DevOpsDays Barcelona community meets before its conference for two talks, hosted by ERNI on the third floor at Plaça de Catalunya. Victor Martín, principal DevOps consultant at ERNI, takes on spec-driven development — the pros, the cons, the pitfalls and what he has learned building with AI while keeping a human on top. Enric Font, DevOps engineer at Adevinta, follows with "I already told you I was trying to get this done before". Welcome at 18:30, talks from 18:45, networking and snacks from 20:15. Free, and close to full at the time of writing. The host requires ID for office access, so fill in the NIF / NIE / passport field when you register or you will not get in. Why go: two engineers from ERNI and Adevinta on what spec-driven and AI-assisted delivery actually does to a pipeline. Best for platform, SRE and DevOps engineers.

with Saba Mamasakhlisi (Engineering Team Lead, Lodgify) · Raul Jimenez (Co-Founder, GolemUI)

Two talks at Lodgify's Eixample office, hosted by the 2,200-member ReactJS Barcelona group. Saba Mamasakhlisi, engineering team lead at Lodgify, goes under the hood of the React Compiler and how automated memoisation replaces hand-written useMemo, useCallback and React.memo. Raul Jimenez, co-founder of GolemUI, then builds a hotel-booking assistant where the agent asks for what it needs, surfaces the right UI at the right moment and lets the user review before committing. Dan Neciu hosts. Doors 18:00, talks from 18:45, drinks and networking 19:50, finish 20:45. Free, with pizza and beer after. Registration is on Luma and the Meetup list is already on a waitlist. Why go: the React Compiler talk is the clearest local account of a change every React codebase is about to hit, and the room is engineers from Barcelona product companies rather than recruiters. Best for frontend and full-stack developers.

Mozilla's flagship festival moves to Barcelona for three days at Fabra i Coats, under the theme Wilding: what happens when rigid digital systems loosen enough for communities and technologies to evolve together. Sessions cover community-owned networks, open protocols, trustworthy AI and tools built on consent rather than capture, run as participatory workshops rather than keynote theatre. Paid ticket, bought through the Mozilla Foundation checkout. Why go: MozFest is the main European gathering of the people building the non-commercial internet, and this is the year it lands in Barcelona. The workshop format means you contribute rather than watch. Best for anyone working on open protocols, digital rights, public-interest technology or trustworthy AI.

with Mario Havel (Ethereum Foundation, Ethereum Foundation) · Rithikha Rajamohan (Founder, V6A) · Jordi Baylina (Speaker, ZisK) + 1 more

An Ethereum community meetup at AKASHA Hub during Mozilla Festival week, on what open, permissionless infrastructure actually lets people build and coordinate. Mario Havel of the Ethereum Foundation opens at 19:00. Rithikha Rajamohan, founder of V6A, follows with Open Sourcing the City; Jordi Baylina of ZisK speaks at 19:30 and Louise Borreani of Ecofrontiers.xyz at 20:00, with open discussion and networking from 20:30. The framing picks up MozFest's Wilding theme and looks at how open protocols grow alongside the wider free and open-source ecosystem. Free, doors 18:00, at AKASHA Hub in Sant Martí. Organised by Ethereum Foundation members with the local Ethereum community. Why go: the MozFest crowd and the Ethereum crowd rarely share a room, and Baylina is one of the most technically serious people working on zero-knowledge in Spain. Best for protocol engineers and anyone building digital public goods.

TechMeetups runs its autumn Barcelona tech job fair at Hotel ILUNION, putting hiring companies and candidates in one room for an evening. Free for candidates. Developer, design, product, data and go-to-market roles are all typically represented, and the format favours short direct conversations with hiring managers over an online application queue. Why go: if you are looking, an evening here is worth more than a week of applications, because you reach the person who decides. If you are hiring, it is the cheapest top-of-funnel in the city this autumn. Best for candidates actively on the market, and for in-house recruiters and hiring managers with roles open now.

with Dani Carmona (Speaker, ) · Victor Garcia (Speaker, )

Three founders on what role is left for Europe in AI, then the debate opens to the room. Itnig hosts it at its own cafe in Poblenou. Two speakers are confirmed, Dani Carmona and Victor Garcia; a third is listed but not named. Talk first, open debate after, with food and drinks so the conversation keeps going. 18:00 to 21:00, held in Spanish, free - a name and an email is all registration asks for. Fourteen people were signed up when we checked. Itnig Cafe is at Carrer de Pujades 100, Sant Marti, in the 22@ district. Why go: few speakers, a small room, and a question European founders actually argue about rather than nod along to. Best for founders and product people building AI products out of Spain.

with Marta Padilla (SVP of Engineering, Eurowag) · Alberto Gutierrez (Product & Tech Advisor, ) · Chloe Beck (Product Manager (moderator), Talent-C)

A panel on the product calls that can sink a company: when to take the risk, when to trust instinct, when to turn round, and how you decide any of it on incomplete information. Marta Padilla, SVP of engineering at Eurowag, and Alberto Gutierrez, a product and tech advisor, take the questions; Chloe Beck, product manager at Talent-C, moderates. The hosts are Talent-R, a Barcelona tech recruitment firm, and the evening runs from their Rambla de Catalunya office with food and drinks after. Free, 18:00 to 21:00. Registration goes through Luma rather than Meetup: the Meetup RSVP on its own will not get you a place. Why go: senior engineering and product people talking about decisions that went badly as well as ones that went well, which is rarer than it should be. Best for product managers, engineering leads and founders weighing a bet-the-company call.

A one-day traveltech summit at the Antiga Fàbrica Estrella Damm covering distribution, AI in booking and service, and the platform economics of the travel sector. Tickets 185 euros. Barcelona holds one of Europe's denser clusters of travel-technology companies, and this is the sector's main autumn gathering in the city. Why go: the attendee list is as much the draw as the stage, so the day pays for itself if you work on the product or commercial side of travel technology. Skip it if you are only adjacent to the sector, because the programme assumes you know how distribution works. Best for product, revenue and partnerships people in travel.

with Alfonso Bustos (Dr, Cambridge Spark)

A roundtable rather than a conference, hosted by Cambridge Spark Spain with Grand Hyatt Barcelona for HR, People, Talent, L&D and digital transformation leaders at companies with a Barcelona presence. The format puts conversation ahead of presentations: a short introduction to the topic, then small-group discussions guided by set questions, a pooling of conclusions, and a closing panel — 'From Insight to Action: What Barcelona's HR Leaders Are Doing About AI Transformation' — featuring Dr Alfonso Bustos. Runs 09:30 to 12:00 at the Grand Hyatt on Avinguda de la Reina Maria Cristina. Free, but places are limited and registration is subject to approval. The invitation is aimed at C-level, directors, heads and managers. Why go: AI-and-work sessions usually end up selling you a platform, and this one instead puts the people who have to land the change in small groups with each other. Best for HR and People leaders at director level or above who are mid-rollout.

with Aleix Valls (Keynote speaker, WeArtificial) · Miguel Vicente (Panellist, Antai Venture Builder) · Ruben Bonet (Panellist, Fractus) + 7 more

Tech Spirit leaves Barcelona for the first time for a half-day evening in Sant Cugat del Vallès, run by the city council with Tech Barcelona. The subject is the Vallès ecosystem: startups, corporates, research centres and universities inside the BIVA alliance. Aleix Valls of WeArtificial keynotes on computation as a company's new operating system. Four panels follow: Antai's Miguel Vicente and Fractus's Ruben Bonet on the local startup scene; Grifols and Boehringer on spin-offs; GFT, HP and Banc Sabadell on open innovation; and a talent panel from UPC, UAB and UIC. Dinner and networking from 20:50. Registration is free through Luma, capacity is limited, and the organising team confirms each place after you sign up. The programme is published in Catalan. Why go: Grifols, HP, Banc Sabadell and Antai on one stage beats most Barcelona evenings for corporate-innovation access, and the Vallès cluster is where a lot of Catalan deep tech sits.

with Ignacio Melero Miguel (Senior Sales Engineer, Snowflake España) · Cesar Segura (Organiser, Barcelona Snowflake User Group)

A hands-on lab, not a talk. You install the CLI, connect to Snowflake and work through three scenarios with Cortex Code (CoCo), Snowflake's AI coding agent. Ignacio Melero Miguel, Senior Sales Engineer at Snowflake Espana, leads it. The three exercises are building a pipeline with Dynamic Tables, evolving that pipeline over time, and creating a Cortex Agent against a Semantic View. Bring a laptop and a Snowflake trial account, which the organisers suggest you set up on AWS in Oregon, and you finish with a Snowflake NorthStar badge. Hosted by the Barcelona Snowflake User Group at SDG Group's offices on Carrer d'Amigo, 18:00 to 20:00, free, with food and drinks afterwards. The listing's body text still carries an earlier edition's date; the event header is 29 October. Why go: two hours with your hands on the keyboard and a Snowflake engineer in the room beats a product demo. Best for data and analytics engineers already working in Snowflake.

with Clara Fernández Pachiani (Lead Product Manager, MANGO) · Tomás Caraccia (Investor and product and engineering leader, Independent)

ProductTank Barcelona's October edition is hosted at MANGO's offices in Poblenou, with two talks and around 120 product people in the room. Clara Fernández Pachiani, lead product manager at MANGO, tackles the question every PM gets asked too early: how much will this sell? Her subject is what to do when you are building products that will not generate revenue immediately, with examples from her own work. Tomás Caraccia, an investor and former software and platform product and engineering leader, follows on how AI speeds up the kind of learning that actually changes company outcomes. Doors 18:30. Free, and currently on a waitlist. Note the entrance is not on Almogàvers — access is via Carrer de Pamplona, the perpendicular street. Why go: a lead PM at a company with real scale on how to justify products that do not pay back this quarter. Best for product managers, founders and anyone who has to defend a roadmap.

The Barcelona edition of BSides, the community-run security conference series: a full day of talks, workshops and networking at the Generalitat's Districte Administratiu on Carrer del Foc. The organisers pitch it as a break from conference norms — a hackers' meet-up with live cyber-action rather than a vendor floor — and say explicitly that it is for people starting out in the field as well as working professionals. Presentations come from industry practitioners, with interactive discussion sessions on current topics running alongside the workshop track. Doors at 09:00, finishes at 18:00, tickets around 27 euros through Eventbrite. Why go: BSides events are where practitioners talk about what actually broke rather than what they are selling, and at under 30 euros for a full day this is the cheapest serious security conference in the city. Best for security engineers, pentesters, blue-team people and anyone trying to break into infosec.

Ninety minutes, one marketing topic, capped at twenty people. Growth BCN's 'Coffee with Marketing Leaders', hosted by Kunoichi Growth and Hello Operator at Samurai Experience on Consell de Cent. Three parts. A short practical session on one current topic, with real examples, tools and tactics. Then an open conversation round the table about what is working, what people are testing, what is overrated and what they have stopped doing — the invitation says no polished success stories required. Then coffee and breakfast with time to talk. Runs 09:30 to 11:00 and you can stay on afterwards. Ten euros early bird, coffee and breakfast included. Questions go to Sophie at Kunoichi Growth. Why go: a twenty-person cap plus a stated no-panels, no-pitches rule is what makes the honest half of these conversations possible at all. Best for in-house marketing leads and heads of growth who would rather not lose half a day.

CARNET's annual symposium, this year on how data and AI are reshaping the automotive value chain and urban mobility, at the UPC civil engineering school on Carrer de Jordi Girona. Doors at 08:30, about five hours. The premise is that vehicles are becoming software-defined, data-generating machines while cities turn into dense networks of sensors and services, and that AI now sits across both: powering connected and automated vehicles, optimising traffic in real time, and giving public administrations new tools to plan and evaluate. Sessions and panels bring together speakers from research centres, automotive companies and public administrations, with case studies on connected and automated vehicles, real-time traffic optimisation and shared data platforms. Free, with paid parking on site. Why go: research, industry and city government in one room on mobility data is specific to Barcelona and hard to assemble yourself. Best for mobility engineers, urban data people and anyone selling into city administrations.

The closing session of the Lighthouse Accelerator, a port and maritime innovation programme run by BlueTechPort with support from Mind the Bridge. Four hours covering the programme's results, the Blue Economy 2026 Report on where ports and the blue economy are heading, and a discussion of sector priorities with ecosystem representatives. The participating startups present their solutions, and the back half is given over to networking between founders, port operators and corporates. It runs in Sala A1 of the World Trade Center's south building on the Moll de Barcelona, 10:00 to 14:00. Registration goes through the Port de Barcelona's own form, which asks for your role and company. No speakers have been named. Why go: the cleanest way into Barcelona's blue-economy and port-tech cluster, which barely surfaces on the usual startup calendars. Best for founders selling into ports and logistics, and for corporates and investors tracking that sector.

with Eleni Anoyrkati (Project coordinator, Coventry University) · Marijana Petrović (Professor, Innovation Centre, Faculty of Mechanical Engineering, Belgrade) · Mario Vukelić (Science & Technology Park, University of Rijeka)

The dissemination event for MobiNexus, an EU mobility project spanning five countries, bringing the consortium together with partners, stakeholders and potential adopters for an afternoon at UPC's Sala d'Actes José Antonio Torroja. The programme presents results across the project's three pillars — electrification, automation and digitalisation — and shows the MobiNexus Digital Platform, Entrepreneurship Academy and User-Centric Lab in use rather than on slides. Registration and a welcome reception from 14:30, then Dr Eleni Anoyrkati of Coventry University, the project coordinator, setting the scene, followed by Prof. Marijana Petrović of the Faculty of Mechanical Engineering in Belgrade and Mario Vukelić of the University of Rijeka's Science and Technology Park on delivering across five countries. A CARNET Barcelona speaker is still to be confirmed. Three hours, free. Why go: EU project results normally reach you as a PDF, and this is the version where you can question the people who built it. Best for mobility researchers and anyone hunting cross-border project partners.

The ocean economy strand of Smart City Expo World Congress, 3 to 5 November at Fira Gran Via, bringing port authorities, maritime operators, ocean-tech startups, investors and policymakers together. Four programmes run under it. Smart Ports: Piers of the Future on port decarbonisation, digitalisation, automation and port-city integration. The Sustainable Ocean Summit for ocean industry leadership. BlueFIN, a curated blue-finance investment programme matching capital with scalable solutions. And the Ocean Innovation Showcase. The organisers frame the whole thing around accelerating solutions that strengthen ocean industries while protecting the ecosystems they depend on, and it sits deliberately inside the wider cities and climate conversation rather than off on its own. Why go: Barcelona is a working port city and this is the one week its maritime technology buyers and the people building for them are in the same building. Best for port and logistics technology teams, ocean-tech founders and blue-economy investors.

with Alexander Wermuth (Global Program Lead, Digital Health Solutions, Roche) · Ghaith Sankari (Health AI Director, Bayer) · Irenee Colin (Digital Health Director, Integrated Health Solutions, Medtronic) + 3 more

Two days of digital health strategy for pharma and MedTech, with sixteen named keynotes. Speakers include Roche's Global Program Lead for Digital Health Solutions Alexander Wermuth, Bayer's Health AI Director Ghaith Sankari and Medtronic's Digital Health Director Irenee Colin, plus leads from Philips, AstraZeneca and Abbott. Sessions are 40-minute presentations with Q&A plus two group stand-ups. Topics include remote patient monitoring evidence, digital biomarkers in neuroscience, image intelligence in diagnosis and accountability in AI-driven pharma operations. Registration from 08:30, opening remarks 08:55 both days. The final rate is €1,590, covering both days, the cocktail night and networking lunches. Run by UBIQ Events. Why go: the people running digital health inside Roche, Bayer, Medtronic and Abbott are in one room for two days, which is unusual outside a trade fair. Best for anyone building for, or selling into, pharma and MedTech.

The world's largest event on urban innovation, three days at Fira Gran Via and the anchor that pulls half of Barcelona's November tech calendar into its orbit. The 2026 congress programme runs with more than 600 international speakers across the themes the organisers put front and centre: responsible AI, data sovereignty, circular cities, energy efficiency, accessibility, sustainable mobility and open governance. Expect city leaders and high-level government representatives alongside 500-plus exhibitors showing market-ready urban systems, with partners from Microsoft, Google, Dell, Deloitte and Veolia through to UN-Habitat, the World Bank, C40 Cities and Eurocities. Terra50, run with Tomorrow.City, showcases fifty climate solutions already deployed and replicable elsewhere. Several parallel congresses sit inside the same venue and pass. Why go: the one week a year when the people who actually buy and deploy city technology are all in Barcelona at once. Best for anyone selling to or working with public administrations, and for urban data and mobility teams.

Europe's deep tech ecosystem meeting inside Smart City Expo World Congress: three days, around 80 speakers, 100 startups and 180 arranged B2B meetings, organised by Biocat at Fira Gran Via. Three main tracks. Augmented Human on how deep tech is extending human capability across health, robotics and space. Deep Intelligence on the infrastructure, governance and capital behind Europe's intelligence era. Corporate Frontier, new this year as a half-day, on how large European corporations are turning deep tech into actual collaboration. Featured speakers include Dirk Didascalou of Siemens, Cristina Caffarra of the EuroStack Initiative Foundation, Elisenda Bou of Cala.AI and Carlos Garcia-Galan of NASA Programmes. Curated one-to-one matchmaking runs through the BDTS Connection Event, and ITF Spain by imec sits alongside it. Why go: pre-market deep tech deal flow and the lab-to-market conversation in one place, which Southern Europe otherwise lacks. Best for deep tech founders and spinoffs, investors, and corporate innovation teams.

The urban mobility congress that runs inside Smart City Expo at Fira Gran Via, with its own programme of around 240 speakers. The agenda is the practical end of mobility rather than the concept-car end: public transport, walkability, accessibility, smart logistics, multimodality, electrification, shared mobility and safe streets, with autonomy treated as one strand rather than the headline. It shares the Smart City Expo exhibition floor and pass, so the 1,100-plus exhibiting companies and government bodies and the city delegations are the same audience, which is the point: the buyers here are transport authorities and municipalities. A startup programme and an AI research showcase run alongside the congress. Why go: mobility suppliers and the public bodies that procure from them in the same hall for three days, which is otherwise a year of meetings. Best for mobility operators, transport planners and anyone selling into transport authorities.

Three days of cybersecurity at Fira Gran Via, Hall 2, running alongside Smart City Expo week and pitched squarely at security leadership rather than at the research community. The tracks are AI and ML, zero trust, cloud and edge, IoT and 5G, quantum security, supply chain security, governance and policy, resilience and incident response, emerging threats, and privacy and ethics. Speakers announced include Marcos Gomez, CISO and Deputy Director of Corporate Security, Connie McIntosh, Head of Security, Tim Brown, partner and CISO in residence, Sounil Yu, Pekka Jokinen and Arvin Bansal. There are separate planned agendas for CISOs and security leaders, for IT and infrastructure, and for compliance and data protection, plus a C-level programme, ISC2 credits, the CISO Leadership Awards and a startup pavilion. Why go: the governance and board-facing half of security, which community conferences cover thinly. Best for CISOs, security architects and compliance leads; practitioners may get more out of BSides Barcelona on 30 October.

with Harald Messemer (ISO 27001 Lead Auditor, ) · Gerardo Prieto (CISO & founder, Barcelona CyberSec) · Xavier Álvarez (Director of Operations, )

Barcelona CyberSec runs its own session inside the Barcelona Cybersecurity Congress: three short talks back to back, then networking, at the Networking Hub in Hall 2 of Fira Gran Via. Harald Messemer, an ISO 27001 lead auditor, opens at 16:00 on moving an ISMS from audit-cramming to a live model with OSCAL evidence. Gerardo Prieto, CISO and founder of Barcelona CyberSec, follows at 16:30 on AI agents that take a vulnerability finding through to a verified fix and know when to ask a human. Xavier Álvarez, director of operations, closes at 17:00 on deepfakes and caller-ID spoofing. Networking from 17:30. Registering on Meetup does not get you in. You need a Barcelona Cybersecurity Congress pass; free community passes go to members of the group's LinkedIn and Telegram. Why go: it is the practitioner track inside a congress that otherwise runs on vendor keynotes. Best for security engineers, CISOs and anyone putting agents near a compliance process.

The fourth Barcelona edition of CNCF Sustainability Month, run by Cloud Native Barcelona with the Green Software Foundation Barcelona chapter and hosted by Schwarz Digits Spain on Carrer de Bergara. It is an annual event from the CNCF Environmental Sustainability Technical Community Group, aimed at environmental sustainability in cloud native and open source. The format is lightning talks: doors 18:30, an hour of ten-minute community talks from 18:45, then food and mingling until 20:30. The line-up is deliberately not fixed in advance: the call for speakers is open until 26 October, and the organisers say a finished project is not required — a new idea, a lesson learned or an open question is enough. Proposals go through bit.ly/cnsm-bcn. Why go: short talks with a low bar to speaking is how you find out what people are actually trying, and the sustainability angle on cloud native is still thin ground. Best for platform and SRE engineers, and anyone with a half-finished idea worth ten minutes.

22@Network Barcelona's afterwork, in a special edition timed for Smart City Expo week and held with Hotel Arts Barcelona on Carrer de la Marina. 22@Network is the association of the companies, startups, universities, technology centres and institutions in the 22@ innovation district, and this edition opens the usual members' evening out to the international delegations and innovation-district representatives in town for the congress. The organisers describe it plainly as an informal evening for meeting people and finding opportunities rather than a programme: no talks, no panels. Doors 18:30, two hours. Ticketed through Eventbrite with no refunds; the Eventbrite total stored against this listing is 18.15 euros, though the public page does not display a price until checkout. Why go: the 22@ district's own network is hard to get into from outside, and congress week is when it opens the door. Best if you want introductions inside Barcelona's innovation district specifically.

with Sharon C. Hsieh (Senior Talent Acquisition Manager / TA Lead, ) · Sofya Nesudimova (HR Business Partner & Talent Strategist (co-facilitator), )

The November edition of womanTech Barcelona's first-Wednesday session, and this one is about finding a job in tech rather than networking. Sharon C. Hsieh, a senior talent acquisition manager and TA lead who has run group-wide talent strategy across startups and scale-ups, takes an interactive session and then a panel: how applicant tracking systems actually filter, how to position a CV and a LinkedIn profile so they get past them, and what recruiters are doing with the current market. Sofya Nesudimova, an HR business partner and talent strategist, co-facilitates. Open Q&A at the end. Free, 18:00 to 20:00, at the Docplanner / Doctoralia office in Sant Martí. Places are capped and building access needs an approved list in advance, so register early. Why go: job-hunting advice from the person on the other side of the screening, in a room small enough to ask the awkward questions. Best for women in tech between roles or weighing a move.

with Sophie Koonin (Staff Engineer, Operations, Monzo) · Wei Ann Heng (Senior Backend Engineer, Subscriptions, Monzo)

Monzo's Barcelona engineers host an evening for women in tech and allies at Aticco Diagrame in the 22@ district, with two short talks from inside the bank. Sophie Koonin, staff engineer on Operations, covers technical migrations at scale: how Monzo goes about upgrading libraries across a very large system, and what that has taught them about running the next migration better. Wei Ann Heng, senior backend engineer on Subscriptions, explains how the team designed Monzo's payday and bill-payment experience to make managing money less work for customers. Roughly 15 minutes each with 10 minutes of questions, then drinks, pizza and networking. Free. Bring ID to get into the building. Why go: migration war stories from a bank running them in production are rarer and more useful than another architecture talk. Best for backend engineers, platform teams and anyone in fintech.

with Hilmi Aydın (Sector Lead, Apps and Gaming, Google) · Cemre Korkmaz (Head of Growth, AI Creativity, Codeway) · Duygu Haykır (Growth Director, Utility, Codeway) + 1 more

The first edition of a growth meetup Codeway is running out of its Barcelona headquarters, together with Google. Hilmi Aydın, Google's sector lead for apps and gaming, opens with a talk on where AI app trends are heading. A panel then follows with three of Codeway's growth leads — Cemre Korkmaz on AI creativity, Duygu Haykır on utility and Abdullah Yıldız on education — covering how the company scales user acquisition. Free and in English, starting at 18:00, with networking over drinks and snacks from 19:00. Applications close on 28 October and places are confirmed on 30 October, so this is approval-gated rather than open registration, and the exact address arrives with the confirmation. Why go: operator-level detail on mobile growth from a team that has done it at scale, with Google in the room. Best for growth, user-acquisition and performance-marketing people in apps and gaming.

with Angelina Gentili (HR Director, Semrush) · Johana Mora (Data Analyst, Conversia Consulting Group)

TechFems takes over the sixth floor at Semrush for a session on what AI is doing to hiring, from both sides of the table. Angelina Gentili, HR director at Semrush, talks about evaluating AI tools in recruitment and how to keep a hiring process fair and inclusive while using them. Johana Mora, data analyst at Conversia Consulting Group, gives the candidate's view after moving into data science herself. The question they are both working on is how to get the benefit of AI without making recruitment less human. Doors and welcome at 18:30, talk at 19:00, networking with refreshments from 20:00. In English, open to everyone, free, with registration through Eventbrite. Bring photo ID. Why go: most AI-and-hiring panels are vendors selling screening tools. This is an HR director and a recent career-changer, which is a far more honest pairing. Best for anyone hiring engineers, and anyone job-hunting.

with Renee Lin (Head of Design, SITA)

UX Hub Barcelona at SITA's Sant Martí office, on designing for the system around a product rather than the product itself. Renee Lin, head of design at SITA, uses a real aviation case to argue that customers' worst problems sit in the gaps between systems, people and organisations, and leaves the room with a framework for mapping them. She has thirteen years across Asia, North America and Europe, building products from zero to one at startups and scaling design teams inside enterprises. Doors 18:30, introduction 19:00, talk 19:15, live Q&A 20:15, networking until 21:30. Free, co-hosted by UX Hub BCN and SITA. RSVP on Meetup plus a short form. Why go: ecosystem design gets talked about a lot and demonstrated rarely, and this is a practitioner showing the work from inside an industry where the seams are unavoidable. Best for product designers and researchers on anything multi-party.

Le Wagon's Barcelona campus hosts an evening of two talks on data products and data security, run in partnership with Women Techmakers Barcelona. The pairing is the interesting part: one half on how data products actually get built, the other on how teams keep sensitive information safe once those products exist. Both talks come from people doing this work day to day rather than from a platform vendor. The format is deliberately relaxed, with time set aside for questions and conversation afterwards. Tickets are €10. The speakers had not been announced when this was written — check the Meetup page before you book if the line-up matters to you. Why go: data security usually gets discussed separately from product work, which is exactly why it arrives late and expensive. An evening that puts both in the same room is worth two hours. Best for data engineers, analysts and anyone shipping a data product.

The twelfth edition of WomanLiderTIC, the Catalan conference on women's leadership in ICT, run by Dones en Xarxa at the Movistar Centre on Placa de Catalunya. A full day of keynotes and panels on careers, digital skills and closing the gap in technology roles, 09:30 to 19:00. It sits deliberately inside Smart City Expo week, when the city is full of people in from elsewhere. Dones en Xarxa says speakers are invited from across Spain, but neither the programme, the speaker list nor a ticket price was published when this was written. In person at Placa de Catalunya 16, 08002. The listing text is in Catalan and Spanish. Why go: twelve editions means the network behind it is real, and this is the Barcelona room for women working in or moving into technical and ICT leadership. Go for the network rather than a named programme, and check the agenda before blocking out the whole day.

PyConES is the Spanish Python community's annual conference, and the 2026 edition runs over three days at the Universitat de Barcelona. Friday 6 November is a half day, 14:30 to 18:30 across five teaching rooms. Saturday is the long day, 07:30 to 18:30, with the Paraninfo and Aula Magna as main stages alongside sponsor-named rooms and a dedicated AI track. Sunday closes at 16:30. Talks are given in both Spanish and English, marked per session in the schedule. Tickets are €75 individual, €110 company and €30 for students with proof of enrolment; student validation can take a couple of days, so do not leave it to the last week. Why go: the largest Python gathering in Spain, in Barcelona this year, with a programme built by the community rather than a conference business. Best for Python developers, data and ML engineers, and anyone hiring them.

with Naomi Bagdonas (Lecturer, Stanford Graduate School of Business) · Felipe Gomez (Keynote pianist, Independent)

Gartner's main European conference for CIOs and IT executives, four days at the International Barcelona Convention Centre, 9 to 12 November. The programme is built around agentic AI, AI technology and infrastructure, cybersecurity and enterprise resilience, emerging technologies, and operating models. Gartner puts the scale at more than 6,500 CIOs and IT executives, over 130 of its own analysts and over 125 solution providers. Named sessions include distinguished VP analysts Kristin Moyer and Daryl Plummer, Shell country chair Marianne Olsnes with CIO Robbert van Rutten, Stanford lecturer Naomi Bagdonas, and guest keynotes from neuroscientist Helena Boschi and digital futurist Andreas Ekström. Paid, and Gartner has not published the registration fee or the daily start times on the event page. Why go: the analyst one-to-ones are the real product, and booking them early is what separates a useful four days from an expensive one. Best for CIOs, enterprise architects and IT leaders setting next year's budget.

A half-day congress on women in science, technology, engineering and maths, at CosmoCaixa in Barcelona, run by Global STEM Women. Eventbrite lists it as in person, 09:30 to 15:00, a five-and-a-half-hour programme at the Museo de la Ciencia CosmoCaixa, Carrer d'Isaac Newton 26. The organiser describes it as a meeting point for female talent in STEM. No speakers, agenda or ticket price are published on the registration page yet. Refunds are available up to seven days before. Why go: CosmoCaixa is a good room and the organiser is an established host, but the programme is still a blank page three weeks out, so treat this as one to watch rather than one to book on the strength of a lineup. Best for women working in STEM in Barcelona who are there for the networking.

with Manel Vericat (Data and AI training specialist, zenital) · Enrico Elio Douglas (Senior Data Engineer, isolutions)

Two sessions at isolutions' Barcelona office on building AI over business data in a way you can actually check. Manel Vericat, data and AI training specialist at zenital, opens at 18:30 with what his team learned building SelfBI, which puts a semantic layer between the model and tables you already trust, and a public-procurement observatory that pulls figures out of PDFs and checks each one against the document's own published statistics. He shows what did not work and what changed because of it. Enrico Elio Douglas, senior data engineer at isolutions, follows at 19:30 on Fabric IQ, tested on a real BI project: what a shared semantic foundation does for answer consistency, and how it layers business context onto existing Power BI models. Doors 18:00, drinks and food from 20:30. Free. Why go: most AI-on-your-data talks stop at the demo. This one is about how you verify the answer. Best for data engineers, analytics leads and anyone shipping a text-to-data layer.

The November networking lunch at El Tros de la Rambla for women investing in startups — angels, syndicate members and fund people. Attendees cover their own lunch. One of very few investor-side events scheduled in Barcelona for mid-November.

The technology strand of Strive Networking's vertical evening at Bestiari, where the same event is sold under sixteen sector labels on one night. Open networking, no programme.

A free evening workshop Le Wagon runs with codebar, aimed at people somewhere between beginner and working developer who are using AI tools and are not sure they are using them well. Two things are on offer side by side: programming fundamentals, and practical ways to work with AI tools responsibly. It suits you if you are learning to code and want guidance from experienced developers, if you are stuck on a personal project, or if you are thinking about moving into tech and want to know what that path looks like now. codebar is a non-profit of students and coaches that runs free coding meetups for women, LGBTQ+ people and others underrepresented in tech, in a deliberately collaborative setting. At Le Wagon's Carrer de la Diputacio space, 18:30 to 20:30. Why go: free one-to-one coaching from working developers is scarce, and the codebar format is built for people who find the usual meetup intimidating. Best for career switchers and self-taught beginners.

How AI models and digital twins are changing what a building technician actually does day to day — surveying, monitoring, predictive maintenance and the data pipeline that connects them. Held at UPC's building engineering school and open beyond the profession.

A hands-on session on Devin, the AI software engineering agent: what it is, how to hand it a task, how to review what it gives back, and how to fit it into an existing workflow. Itnig hosts at its cafe in Poblenou. The agenda is set - registration 18:00, introduction 18:30, an hour of building with Devin from 19:00, project presentations at 20:00, then networking. No speakers are named. Free, capacity limited, attendance has to be confirmed. One caveat from the page itself: the header says the session is in Spanish while the practical information says English with English Q&A. Worth asking the organisers before you commit. Why go: most agent talks are slides. This one puts the thing in front of you for an hour with other engineers in the room. Best for backend and platform engineers weighing up coding agents.

The Barcelona edition of DevOpsDays, two days on 13 and 14 November at BAU, Centre Universitari d'Arts i Disseny, in Poblenou. DevOpsDays is a volunteer-run community conference series rather than a vendor event. The 2026 call for papers was still open when this was written, so no speakers or schedule are published; the organisers point to a separate schedule site. Platinum sponsors are Datadog, Grafana Labs and Progress, with Red Hat as supporter. Tickets go through tickets.devopsdays.org and no prices are listed. Daily start times are unpublished, which is why this listing carries no time. Why go: DevOpsDays rooms are where platform and SRE people say what actually broke, and Barcelona's edition has pulled a serious sponsor list for a community conference. Best for platform, SRE and infrastructure engineers.

Safe Software brings its FME Breakfast of Champions to Barcelona: a free morning for data and GIS engineers on spatial data integration, automation pipelines and what teams here are building with FME. Technical, hands-on and openly registerable.
