Job description

Help make Graphcore hardware feel native inside the ML frameworks engineers use every day.

As a Software Engineer in our PyTorch team, you will help build the software that connects Graphcore accelerators with state-of-the-art machine learning frameworks. You will design, implement, optimise and support features across PyTorch, Triton and related technologies.

Your work will help ML engineers and researchers get more from Graphcore hardware, without changing how they want to build. That means better compatibility, stronger performance and cleaner developer experiences.

You will contribute to upstream PyTorch, support our hybrid Python and C++ extension, and help integrate compiler backend capabilities with torch.compile. You will learn fast, solve real engineering problems and build expertise in a large open-source ecosystem.

The team and culture

You will join the PyTorch team within Frameworks, working in a SCRUM team that ships features, reviews code, writes documentation and supports users. Work happens through clear ownership, practical decisions and close communication across software, AI/ML, research and hardware teams.

The team values maintainable code, thoughtful design and curiosity about unfamiliar systems. Engineers are trusted to investigate, speak up and improve the codebase as they learn.

This is a team for people who like open-source communities, complex technical problems and visible impact. You will move quickly, but with care for users and long-term quality.

What we're looking for

• Strong core software engineering skills and a collaborative team mindset
• Experience developing Python libraries
• Experience building performant C++ applications in a commercial setting
• Understanding of linear algebra, floating-point arithmetic or numerical analysis
• Confident using Git and reviewing code in a commercial team setting
• Willingness to explore large, unfamiliar open-source codebases independently and with others

• 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.
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.
