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.

What we’re looking for

• Bachelor’s or Master’s degree in Electrical Engineering, Materials Science, Physics, Mechanical Engineering, or a related field
• Strong semiconductor reliability experience across silicon, BEOL, interconnect or advanced package technologies
• Deep understanding of mechanisms such as EM, TDDB, BTI and HCI
• Hands-on experience with HTOL, thermal cycling, thermal shock, reflow testing and JEDEC reliability standards
• Ability to use X-ray and CSAM analysis to diagnose package defects and support root-cause analysis
• Strong technical judgement, communication skills and ownership across foundries, OSATs, labs and internal teams

While we have outlined a set of requirements, we value transferable skills and diverse experiences. If you meet most of our essential criteria, we encourage you to submit an application and showcase how your background makes you a strong candidate.

Benefits

• Flexible working: Balance your work and personal life with greater flexibility
