About the job
Debug the high-speed interfaces that decide whether advanced AI systems perform in the real world.
As a Validation and Debug Engineer, you will help prove Graphcore silicon and platforms work across real product conditions. You will build deep knowledge of our devices, boards and system behaviour.
You will own hands-on validation and debug in the lab, focused on SerDes, PCIe Root Complex and Ethernet. Your work will help resolve complex issues across silicon, hardware, firmware and architecture teams.
This role is for someone who enjoys getting close to the hardware. You will tune links, investigate failures and turn difficult lab findings into clear engineering decisions.
The team and culture
You will work closely with Architecture, Silicon Engineering, Hardware Engineering and Firmware. Progress comes through practical evidence, clear communication and fast problem solving.
The team expects ownership without daily oversight. You will drive bring-up, debug issues and help teams reach decisions based on data.
You will be trusted to speak up when something is unclear or risky. The best ideas can come from anyone close to the problem.
What we’re looking for
· Strong hands-on hardware validation experience, including board bring-up and subsystem debug
· Experience validating and debugging Ethernet, PCIe Root Complex and SerDes systems
· Confident use of lab instrumentation, including oscilloscopes, BERT systems, VNA/TDR equipment and PCIe protocol analysers
· Ability to debug signal integrity, protocol-level and interface issues through to root cause
· Experience with PCIe bring-up, LTSSM analysis, link training, equalization tuning and interoperability testing
· Ability to work independently, take responsibility and drive issue resolution across teams
While we have outlined a set of requirements, we value transferable skills and diverse experiences. If you meet most of our essential criteria, we encourage you to submit an application and showcase how your background makes you a strong candidate.
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
· Peace of mind protection: Income protection and life assurance to provide financial security for you and your loved ones
· Flexible benefits: Tailor your benefits package with a choice of additional options, including private medical insurance and dental cover
· Optional benefits: Dental cover, health cash plan, private medical insurance, cycle to work scheme, give as you earn
We welcome people from all backgrounds and experiences and are committed to building an inclusive environment where everyone can do their best work.
