About the Job

Graphcore is expanding its Silicon Architecture Team in Bristol to deliver complex AI compute platforms. As a SoC Architect, you will define how critical subsystems are specified, modelled, and integrated. You will turn product requirements into architecture choices across interfaces, interconnect, memory, and platform behavior. Your work will guide implementation, validation, and trade-offs across multiple chip programs. You will work with processor, SoC, and system architects, plus design, verification, hardware, and software teams. Together, you will evaluate IP, resolve integration questions, and support silicon bring-up where needed.

This is a rare chance to influence real AI silicon while Graphcore scales its contribution to SoftBank Group's AI ecosystem.
