Graphcore is a Bristol-based AI semiconductor company building Intelligence Processing Units for machine learning workloads, now part of SoftBank. They're hiring a Power Integrity Engineer in London (hybrid). This electrical engineering role sits within the UK's AI semiconductor sector.
Shape the power delivery architecture behind next-generation AI compute systems.
You will develop power integrity solutions across silicon, package, PCB and system designs. Your work will directly influence performance, reliability and scalability across advanced AI platforms.
You will model and analyse complex power delivery networks, optimise decoupling strategies and solve integrity challenges before systems reach production. You will work closely with chip, package and board teams to turn simulation insight into design improvements.
This role offers rare end-to-end ownership across the hardware stack. You will help define how high-current, high-performance AI systems are designed, validated and brought to life.
The Signal and Power Integrity team works at the centre of Graphcore’s hardware development. The team partners closely with silicon, package, board and systems engineers to solve complex electrical challenges early.
Work moves quickly and decisions are driven by data, simulation and measurable outcomes. Engineers are trusted to challenge assumptions, improve methodologies and raise technical standards across programmes.
You will join a team that values deep technical thinking, practical problem-solving and shared ownership. People contribute directly, speak openly and support each other through complex design cycles.

Graphcore is a Bristol-based AI semiconductor company founded in 2016 by serial semiconductor entrepreneurs Nigel Toon and Simon Knowles. Toon previously led XMOS and Picochip, while Knowles co-founded Element14 (acquired by Broadcom) and Icera (acquired by NVIDIA for $435M). The company developed Intelligence Processing Units (IPUs), novel AI accelerators designed from the ground up for machine learning workloads, alongside the proprietary Poplar graph programming framework. Graphcore raised $767M in total funding, reaching a $2.77B valuation, with backing from Sequoia Capital, Atomico, Amadeus, Microsoft, and others. In July 2024, SoftBank Group acquired Graphcore for approximately $500M to $600M. The company continues to operate from Bristol with plans to expand its UK headcount to 750.
