Signal Integrity Engineer

<p class="p1"><span class="s1"><strong>About the job</strong></span></p> <p class="p1"><span class="s1">Own signal integrity for the interconnects that make advanced AI compute systems reliable at scale.</span></p> <p class="p1"><span class="s1">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.</span></p> <p class="p1"><span class="s1">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.</span></p> <p class="p1"><span class="s1">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.</span></p> <p class="p1"><span class="s1">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.</span></p> <p class="p1"><span class="s1">&nbsp;</span></p> <p class="p1"><span class="s1"><strong>The team and culture</strong></span></p> <p class="p1"><span class="s1">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.</span></p> <p class="p1"><span class="s1">Ownership sits close to the engineering problem. You will guide layout decisions, challenge assumptions and use evidence to move designs forward quickly.</span></p> <p class="p1"><span class="s1">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.</span></p> <p class="p1"><span class="s1">&nbsp;</span></p> <p class="p1"><span class="s1"><strong>What we’re looking for</strong></span></p> <ul class="ul1"> <li class="li2"><span class="s1">Strong signal and power integrity capability across high-speed digital hardware.</span></li> <li class="li2"><span class="s1">Deep understanding of transmission lines, impedance control, loss, crosstalk, jitter, return paths and power delivery.</span></li> <li class="li2"><span class="s1">Practical experience with multi-gigabit SerDes, DDR or other advanced board-level interfaces.</span></li> <li class="li2"><span class="s1">Experience using SI/PI and electromagnetic tools such as ANSYS SIwave, HFSS, Siemens HyperLynx or equivalent.</span></li> <li class="li2"><span class="s1">Hands-on lab experience using VNAs, high-speed oscilloscopes, signal generators and related measurement equipment.</span></li> <li class="li2"><span class="s1">Ability to turn simulation data, lab results and system requirements into sound engineering decisions.</span></li> </ul> <p class="p1"><span class="s1">&nbsp;</span></p> <p class="p1"><span class="s1"><strong>Benefits</strong></span></p> <p class="p1"><span class="s1">· Unlimited annual leave<br>· Up to 5% matched pension<br>· Phantom equity – share in Graphcore’s success<br>· True flexibility in how and where you work<br>· Office spaces designed for collaboration<br>· Free food and an on-site barista<br>· Health cash plan<br>· Income protection<br>· Life assurance<br>· Along with other benefits you can choose from (private medical insurance, dental plan etc)</span></p> <p class="p1"><span class="s1">&nbsp;</span></p> <p class="p1"><span class="s1">We welcome people from all backgrounds and experiences and are committed to building an inclusive environment where everyone can do their best work.</span></p> <p class="p1"><span class="s1">We’re an equal opportunity employer and recognise that everyone brings different strengths and perspectives.
