Graphcore · Cambridge

Design and build production-quality test infrastructure and CI/CD pipelines that validate Graphcore's ML software stack across simulators, emulators and physical AI accelerator hardware. Create representative ML workloads, analyse numerical accuracy and performance, and shape test architecture and developer experience while mentoring junior engineers.

Graphcore · Bristol

Hands-on role owning reliability of AI compute hardware from lab bring-up to data centre deployment. You will diagnose failures across server blades, racks, power, thermal, network and BIOS/BMC issues, lead root cause analysis and improve hardware diagnostics while guiding junior engineers.

Graphcore · Bristol

Designs and validates high-speed signal paths for AI compute hardware, covering 112Gbps and 224Gbps SERDES, DDR and processor interfaces. Involves PCB structure extraction and simulation, defining launches, vias, transmission lines and stack-ups, plus lab validation with VNAs and oscilloscopes from concept through prototype bring-up and manufacture support.

Graphcore · Bristol

Define and implement DFT architecture and features for next-generation AI silicon aimed at data centre applications, developing DFT flows and methodologies and supporting their verification. Work spans structural test vectors, test coverage, scan-based testing and ATPG, alongside silicon bring-up and yield learning with design, verification, physical design and product engineering teams.

Graphcore · Bristol

Design, implement and optimise software that connects Graphcore accelerators with ML frameworks such as Triton and PyTorch. Working in the Frameworks team, you deliver new features, review code, write documentation and collaborate with upstream open-source communities, with deep technical ownership across a complex stack.
