Graphcore - Principal Hardware System Test Engineer

• Essential • Extensive experience developing and deploying manufacturing test solutions for high-performance servers, accelerators (GPU-class), or comparable large-scale compute hardware. • Proven technical leadership as an individual contributor, owning architecture and driving alignment across multiple teams without direct line management responsibility. • Deep technical understanding across silicon, board, and system design sufficient to define effective manufacturing test coverage and lead complex debug/root-cause analysis. • Strong cross-functional collaboration skills, with experience driving requirements and delivery with internal software/firmware/platform teams to enable testability and diagnosability. • Hands-on experience using Linux, OpenBMC, and vendor-specific test tools, diagnostics, and system-level utilities to test hardware in lab and manufacturing environments. • Strong software engineering skills with scripting and automation (e.g., Python, Bash, or similar), including building reliable test infrastructure and integrating heterogeneous test content. • Desirable • Familiarity with rack-scale/multi-node systems, high-speed interconnects, and production qualification of complex assemblies. • Experience improving manufacturing KPIs (yield, test time, false fail reduction) through data-driven test optimisation and robust statistical/diagnostic approaches. • Knowledge of open-source tools commonly used for manufacturing test, system bring-up, and hardware diagnostics. • Experience designing testability/diagnosability features into products (e.g., telemetry, self-test hooks, debug interfaces) in partnership with design teams.
