You will lead a team delivering post-silicon validation across the full AI SoC, working across silicon, firmware, and platform levels. The role requires a deep technical understanding, strong hands-on debug experience, and the ability to collaborate effectively with hardware, software, and systems engineering teams.

Responsibilities

• Define and lead post-silicon validation strategy: Develop and refine the overall post-silicon validation approach for our AI SoCs, ensuring reliable and timely delivery of validated silicon, architectural correctness, feature robustness, and at-scale system reliability
• Drive cross-domain debug and issue resolution: Lead investigation and resolution of complex issues spanning silicon, firmware, operating systems, and platform interactions. Ensure that fixes are effective and sustainable
• Promote collaboration and shared understanding: Work closely with design, software, and validation teams to align on quality objectives and debug priorities. Use data-driven insights and clear communication to maintain focus and alignment across teams
• Advance automation and scalable validation: Encourage the use of emulation, prototyping, and large-scale validation infrastructure to improve coverage and reduce time to debug
• Support continuous improvement: Foster a culture that values learning, transparency, and improvement in validation methods, automation, and analysis
• Engage with leadership and customers: Provide clear and concise updates on validation progress, risks, and quality indicators to executive teams and key partners. Contribute to product readiness assessments and roadmap decisions

Essential skills

• A systems thinker, comfortable working across hardware, software, and integration boundaries
• A collaborative leader who builds trust and alignment across diverse teams
• Skilled in technical problem solving and debugging complex post-silicon issues
• A clear communicator who can simplify complexity and support sound decision-making in fast-paced environments
• Committed to developing people and promoting an inclusive, high-performing team culture
• Bachelor’s degree in Electronic Engineering or equivalent; Master’s preferred
• 20+ years in silicon, system, or platform validation, including 10+ years in technical leadership
• Proven experience leading post-silicon validation and bring-up for complex SoCs (AI, GPU, or CPU)
• Strong understanding of SoC architecture, coherency protocols, power management, and interconnects
• Expertise in debug tools, DFT infrastructure, and validation automation frameworks
• Proficient in C/C++, Python, and Linux-based environments; experience with large-scale validation clusters is an advantage

Benefits

In addition to a competitive salary, Graphcore offers flexible working, a generous annual leave policy, private medical insurance and health cash plan, a dental plan, pension, life assurance and income protection. We have a generous parental leave policy and an employee assistance programme (which includes health, mental wellbeing, and bereavement support). We welcome people of different backgrounds and experiences; we’re committed to building an inclusive work environment that makes Graphcore a great home for everyone. We offer an equal opportunity process and understand that there are visible and invisible differences in all of us. We can provide a flexible approach to interview and encourage you to chat to us if you require any reasonable adjustments.
