About the job
Own signal integrity for the interconnects that make advanced AI compute systems reliable at scale.
As a Signal Integrity Engineer, you will shape the high-speed PCB and interconnect structures behind Graphcore’s next AI compute platforms. You will take technical ownership across board, package and system-level design.
Your work will help advanced digital interfaces perform within demanding system budgets. That means stronger hardware, cleaner bring-up and greater confidence in first-time-right delivery.
You will develop, extract, simulate and validate structures for SerDes, DDR and other high-speed interfaces. You will turn complex requirements into practical design rules, then prove them through simulation and lab correlation.
This is a role for someone who enjoys difficult physical design problems. You will influence decisions early, move between models and measurements, and raise the standard for future hardware.
The team and culture
Hardware Engineering works across the full hardware lifecycle, from architecture and implementation to bring-up, validation and production support. Engineers work directly with silicon, package, PCB, firmware, software, systems and supplier teams.
Ownership sits close to the engineering problem. You will guide layout decisions, challenge assumptions and use evidence to move designs forward quickly.
Decisions are made through clear technical reasoning, open discussion and measured results. The team values people who speak up, take responsibility and turn ambiguity into progress.
What we’re looking for
- Strong signal and power integrity capability across high-speed digital hardware.
- Deep understanding of transmission lines, impedance control, loss, crosstalk, jitter, return paths and power delivery.
- Practical experience with multi-gigabit SerDes, DDR or other advanced board-level interfaces.
- Experience using SI/PI and electromagnetic tools such as ANSYS SIwave, HFSS, Siemens HyperLynx or equivalent.
- Hands-on lab experience using VNAs, high-speed oscilloscopes, signal generators and related measurement equipment.
- Ability to turn simulation data, lab results and system requirements into sound engineering decisions.
