You’ll help specialists shape requirements, design margins and acceptance criteria across silicon, package, PCB and system boundaries. Your team’s constraints and verification evidence will help design owners make informed trade-offs before problems become harder to resolve. You’ll line-manage engineers, shape their development, agree achievable delivery commitments, and plan for tools, licences and compute capacity. You’ll coordinate analysis and hardware correlation, ensuring discrepancies receive specialist attention and integrity issues reach review and closure. The methods and knowledge your team builds will outlast individual designs, strengthening how Graphcore approaches future signal and power challenges. Grow your leadership across interconnected engineering disciplines, combining people development with judgement that influences hardware from architecture to bring-up. The team and culture Signal and power integrity specialists retain technical ownership, rather than relying on one person to solve every problem. You’ll connect their work with design, firmware, test, bring-up and manufacturing colleagues. Programme management owns the integrated plan. You’ll raise capacity conflicts early, bring practical options and make delivery confidence visible. Decisions depend on evidence, documented assumptions and proportionate peer review. You’ll encourage challenge, seek specialist input when needed and escalate unresolved disagreements before they hold work back. ## What we’re looking for - People leadership that develops engineers, sets expectations and addresses difficult performance issues, with readiness for formal line management. - Strong engineering foundations and experience in signal or power integrity, with sufficient understanding of the other discipline to challenge approaches. - Experience coordinating specialist engineering delivery, including estimates, work allocation, dependencies and capacity, in partnership with programme management. - Clear cross-disciplinary communication that explains risks and trade-offs, secures specialist contributions and helps stakeholders reach decisions. - First-principles reasoning and understanding of simulation, measurement and correlation, including model limitations and when to seek specialist review. - Evidence of improving engineering methods or shared knowledge, while maintaining clear ownership through technical investigations. 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 - Peace of mind protection: Income protection and life assurance to provide financial security for you and your loved ones - Electric Vehicle Scheme: Choose an electric vehicle and lease it through salary sacrifice - 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. We’re an equal opportunity employer and recognise that everyone brings different strengths and perspectives. If you need any adjustments during the interview process, just let us know - we’re happy to support you. Sponsorship Applicants must have the legal right to work in the UK. Unfortunately, we are unable to provide visa sponsorship or support visa applications for this role.
