Principal Systems Test Operations Engineer

About the job

Shape how Graphcore’s high-performance systems are tested, diagnosed and proven ready for production.

You’ll lead the technical direction for system-level manufacturing test. You’ll turn product requirements into robust test strategies for manufacturing partners.

Your work will directly influence product quality across boards, blades and rack-level systems. You’ll solve complex test issues and drive improvements across products.

You’ll define, deploy and maintain test platforms, fixtures and diagnostic solutions. You’ll also partner with hardware, software and manufacturing teams.

This role combines hands-on technical depth with broad influence. You’ll shape future test strategy while helping other engineers raise the bar.

The team and culture

The Product Test and Diagnosis team finds and manages hardware defects across chips, boards and finished systems. Its work spans manufacturing sites and deployed products.

You’ll work closely with engineering teams and manufacturing partners to solve problems quickly. Decisions are driven by evidence, technical judgement and root cause analysis.

You’ll have ownership of complex problems and the scope to challenge existing approaches. You’ll also mentor engineers and establish practical standards across teams.
