Shape the SoC architecture behind Graphcore's next generation of AI acceleration platforms.
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 behaviour. Your work will guide implementation, validation and trade-offs across multiple chip programmes. 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.
The team and cultureThe team owns SoC architecture, subsystem modelling and system-level trade-offs across future AI acceleration platforms. Work moves from requirements to specifications, models, reviews and guidance for implementation teams. People here are expected to take responsibility early and keep decisions moving. You will speak directly with adjacent teams to clarify constraints, challenge assumptions and close open questions. Decisions are made through technical evidence, clear specifications and direct cross-functional discussion. The team values people who think big, act fast and speak up when architecture needs sharper choices.
What we're looking for• Experience specifying or architecting complex SoC devices or subsystems.
• Strong understanding of computer architecture, SoC integration, RTL development and verification processes.
• Ability to turn product requirements into clear technical specifications and practical design trade-offs.
• Software development capability, ideally with Python, C++, Rust or architecture modelling experience.
• Knowledge of PCIe, LPDDR, DDR, Ethernet, high-speed interfaces or on-chip interconnect.
• Confidence working across design, verification, hardware, software and systems teams.
While we have outlined a set of requirements, we value transferable skills and diverse experiences. We also welcome engineers returning to the profession after a career break, including through returnship routes.
Benefits· Flexible working: Balance your work and personal life with greater flexibility
· Generous leave: Take time to rest, recharge and enjoy life outside of work
· Retirement planning support: Up to 5% matched pension
· Phantom equity: Share in Graphcore’s success
· Workplace experience: Enjoy thoughtfully designed office spaces for collaboration, with free food and an on-site barista to support your day
