## Description

As Staff Power Integrity Engineer, you will provide technical leadership on Graphcore's most complex power-delivery challenges.

Your analysis and judgement will directly influence architecture and product decisions.

You will define modelling strategies, optimise decoupling and analyse PDN impedance, voltage droop, transient response and regulator interactions.

You will turn complex results into clear engineering decisions, requirements and sign-off approaches.

You will lead significant PI issues through resolution and create alignment across silicon, package, board, power, systems and validation teams.

You will also develop reusable methods and mentor engineers, raising power-integrity capability across Graphcore.

The Signal and Power Integrity team sits at the centre of Graphcore's hardware development.

We work across disciplines to understand electrical behaviour and guide consequential architecture decisions.

Decisions are grounded in modelling, first-principles reasoning, hardware evidence and clear assessment of uncertainty.

You will challenge assumptions, communicate risk clearly and help teams make pragmatic trade-offs.

Technical influence matters more than reporting lines.

Requirements:

- Deep practical expertise in power integrity and complex power-delivery network design.

- Strong understanding of PDN impedance, transient behaviour, voltage droop, resonance, stability and decoupling across high-current digital systems.

- Ability to reason across silicon, package, PCB, voltage regulation and system boundaries.

- Strong capability in electromagnetic modelling, circuit simulation, model extraction and selecting appropriate abstraction methods.

- Engineering judgement to assess model validity, uncertainty and sensitivity, then translate analysis into architecture and product decisions.

- Ability to lead ambiguous technical work, influence across engineering disciplines, improve methodology and develop other engineers.

Benefits:

- Flexible working

- Generous leave

- Retirement planning support: up to 5% matched pension

- Phantom equity

- Workplace experience: thoughtfully designed office spaces for collaboration, with free food and an on-site barista

- Peace of mind protection: income protection and life assurance

- Electric Vehicle Scheme

- Flexible benefits: tailor your benefits package with a choice of additional options

- Optional benefits: dental cover, health cash plan, private medical insurance, cycle to work scheme, give as you earn
