PyTorch Engineer

Location: Bristol, UK

Department: Frameworks

About the job

Make PyTorch feel native, powerful and production-ready on Graphcore AI compute.

You will help build the software layer that connects Graphcore accelerators with state-of-the-art machine learning frameworks. Your work will shape how ML engineers and researchers use our hardware in real workloads.

You will design features, improve performance, maintain core code, and support users working at the frontier of AI. You will work deeply in PyTorch, with scope to contribute across other frameworks as the landscape evolves.

This is a role for engineers who enjoy hard technical problems and open-ended ownership. You will influence architecture, quality and direction while helping Graphcore unlock the next generation of AI breakthroughs.

The team and culture

The Frameworks team makes Graphcore hardware work seamlessly with the tools ML engineers already use, including PyTorch, Triton, JAX and TensorFlow. Work happens through agile practices, clear technical debate and close links with hardware, software and open-source teams.

You will join a Scrum team that owns features from design through delivery, performance, documentation and support. Engineers are expected to take responsibility, speak up early and make decisions grounded in evidence.

The team values pace without losing quality. You will be trusted to coordinate complex work, manage trade-offs and help others grow through reviews, mentoring and shared learning.

What we're looking for

· Strong software engineering skills, with the judgement to manage quality, complexity and delivery.
· Experience developing in Python.
· Experience building performant C++ applications in a commercial setting.
· Experience in at least one of ML kernels, compiler development, ML frameworks or computationally intensive engineering.
· Ability to coordinate complex technical tasks with cross-team dependencies.
· Clear communication, ownership and curiosity about how high-performance software works.

Benefits

· Unlimited annual leave
· Up to 5% matched pension
· Phantom equity – share in Graphcore’s success
· True flexibility in how and where you work
· Office spaces designed for collaboration
· Free food and an on-site barista
· Health cash plan
· Income protection
· Life assurance
· Along with other benefits you can choose from (private medical insurance, dental plan etc)

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.
