Power Integrity Engineer
Job description
About the role
This role defines and executes power integrity strategies across the full system path from silicon to board. The position drives analysis and implementation so that complex packages, PCBs and hardware platforms operate dependably. You will own the development of power delivery networks that ensure robust and noise-free operation across all Graphcore silicon and systems. The role requires a deep partnership with hardware and system engineering teams to validate designs through simulation and measurement. You will guide the technical direction of power integrity from initial bring-up through to high-volume manufacturing. A core part of this position is translating measurement data into actionable design improvements for future platforms. The work directly influences the reliability and performance of next-generation AI compute infrastructure. Strong ownership of engineering detail and clear communication of technical trade-offs are central to succeeding in this position.
Key facts
What you'll do
Conduct power integrity analysis across the complete system path, from silicon die through package to the final board implementation.
Define and execute decoupling strategies, power stack-up choices, and bring-up debugging procedures to achieve target power behaviour.
Collaborate cross-functionally with hardware and system engineering teams to elevate power and signal performance from concept to production.
Interpret complex simulation results and translate findings into concrete design improvements that mitigate risk and enhance reliability.
Guide technical decisions, review peer work, and constructively challenge designs to ensure ownership remains close to the engineering detail.
Drive the development and validation of power delivery networks using electromagnetic and circuit simulation methods.
Perform lab measurements using VNAs and oscilloscopes to correlate models with real-world performance and validate simulation accuracy.
Establish best practices for power integrity that can be applied across future Graphcore platforms and silicon generations.
Act as a subject matter expert within the Systems Engineering Hardware Motherboard team, influencing standards and methodologies.
Ensure all power integrity work aligns with the broader goals of reliability engineering for AI compute systems.
Support the creation of documentation and technical narratives that explain power behaviour to both technical and non-technical stakeholders.
Identify and mitigate potential power-related risks early in the design cycle to avoid costly re-spins and production delays.
Champion the use of simulation tools to verify power delivery and validate that designs meet stringent noise and stability criteria.
Foster a culture of end-to-end problem ownership where analysis, measurement, and collaboration define the team's success.
Requirements
Demonstrate a thorough grasp of power integrity principles, including PDN design and analysis, as a mandatory skill set.
Possess expertise with PI simulation tools such as PowerDC, PowerSI, HFSS/SiWave, Simplis, Spice, ADS or comparable platforms.
Bring hands-on experience across chip, package, or board-level design to understand the full impact of power delivery.
Show the ability to interpret simulation results and translate them into actionable design improvements.
Apply electromagnetic simulation methods and lab measurements using VNAs and oscilloscopes as standard parts of the workflow.
Exhibit strong analytical abilities, clear communication, and effective cross-functional collaboration skills.
Hold a Bachelor's degree or equivalent experience that demonstrates a foundational knowledge of electrical engineering or a related field.
Have the legal right to work in the UK, ensuring compliance with visa requirements before applying for the role.
Nice to have
Experience with reliability engineering methodologies specific to power delivery in high-performance computing environments.
Familiarity with advanced electromagnetic simulation tools and their application in verifying power integrity.
Understanding of how power integrity intersects with signal integrity and thermal management in complex systems.
Practical notes
The team operates through modelling, simulation, validation and lab evidence as a standard workflow.
Typical interview steps
Hiring for engineering roles usually starts with a recruiter screen, followed by one or two technical rounds. Candidates often solve a coding problem, discuss past projects, and answer system design questions. Some loops include a take-home task. Final rounds typically cover team fit and give candidates a chance to ask questions. Interviewers look for how you break down an unfamiliar problem, not just whether you reach the answer. Practicing a few problems aloud and reviewing your own past projects are the best preparation.
Good to know
Reliability engineering shapes power delivery for AI compute systems. Electromagnetic and circuit simulation tools drive design analysis and verification. Collaboration spans hardware and system engineering disciplines. End-to-end problem ownership defines team culture and decision making. The work contributes to next-generation AI infrastructure within a large-scale innovation organisation.
Questions to ask
Worth asking in any interview: how the team measures success, who the role works with daily, what the onboarding looks like, and what the company is trying to achieve this year. Asking what past hires did well is a strong final question. Keep the list short and pick the questions that matter most to you.
Career growth
Engineering careers usually progress from individual contributor to senior, staff, and principal levels. Some engineers move into management and lead teams of five to twenty people. Others stay on the technical track. Growth follows demonstrated impact, not tenure alone. A typical engineering ladder has clear levels with defined expectations for scope, quality, and mentorship. Moving up usually requires owning outcomes end to end rather than completing assigned tickets.
