Job description

About the job

Own the reliability strategy behind advanced AI silicon built for datacenter scale.

Graphcore is expanding the hardware platforms that will power the next generation of AI compute. As Senior Semiconductor Reliability Engineer, you will lead reliability strategy across advanced silicon nodes and packaging technologies.

You will shape reliability from technology selection and design enablement through bring-up, qualification and manufacturing. Your work will help complex, high-performance devices move from ambitious design into robust production.

You will assess risk, guide sign-off, lead qualification and drive failure analysis across silicon, interconnect and package technologies. This is a rare role at the centre of device physics, design, packaging and manufacturing.

The team and culture

You will work across silicon, packaging, manufacturing and quality, connecting technical detail with product-level decisions. Work moves through direct ownership, clear evidence and fast escalation when risks need attention.

Decisions are grounded in data, modelling, qualification results and open technical debate. You will be expected to speak up, challenge assumptions and turn complex findings into clear next steps.

This is a role for someone who thinks beyond individual tests. You will help build stronger reliability methods and mentor others as Graphcore scales advanced AI hardware platforms.
