The role

What you’ll do

Own the compute engine architecture specification, trading off performance, power, area and complexity
Build and use performance models and simulators to steer architectural choices
Work with logic design, physical design and verification to turn the spec into silicon
Assess new ideas such as compact number formats and advanced packaging for the roadmap

What you’ll need

Proven experience as a processor, CPU or GPU architect in semiconductors or high-performance computing
Deep knowledge of matrix and vector floating-point compute and memory hierarchies
Experience taking a processor design from early exploration to tapeout and post-silicon characterisation
Understanding of RTL flows and physical design constraints and how they shape architecture
