Job Summary

As the Hardware System Test Engineering Manager, you will lead the Hardware System Test Team responsible for developing manufacturing test solutions for High Performance Modules, Server Blades and Multi‑node racks as part of the production assembly process. You will drive the creation of robust test executive software that sequences tests and integrates test content from multiple internal and external sources, guide the development of manufacturing test content and test fixtures informed by a deep understanding of silicon, board and system design, and work cross‑functionally with hardware, firmware and software teams to ensure the right tools and functionality exist to efficiently validate product quality at scale.

The Team

The Product Test and Diagnosis team is responsible for identifying and diagnosing hardware defects introduced during the manufacturing process. The team defines, develops and executes an end‑to‑end test strategy spanning silicon, board‑level assemblies, server blades and rack‑scale systems. Testing is performed across the full product lifecycle, including manufacturing and deployed field environments. Product Test and Diagnosis is part of the Manufacturing Operations organisation, which also comprises Manufacturing Technology, Supply Chain and Quality teams. The group operates as a global team, with engineers based in the UK (Bristol and Cambridge), Taiwan, India and the United States.

Responsibilities and Duties

• Lead and grow a multidisciplinary team of hardware and software test engineers delivering manufacturing test solutions for complex compute systems.
• Define the manufacturing test strategy and roadmap for High Performance Modules, Server Blades and Multi‑node racks.
• Own delivery of test executive software used in both manufacturing and lab environments to orchestrate test sequencing, logging, results aggregation and integration of test content from diverse sources.
• Partner with internal software, firmware and platform teams to ensure required hooks, diagnostics, telemetry and APIs exist to enable effective manufacturing test.
• Establish best practices for test coverage, traceability, release management and configuration control of test software and content.
• Implement metrics and dashboards for manufacturing test (yield, escapes, false fails, coverage, cycle time) and lead continuous improvement initiatives.
• Drive root‑cause analysis of manufacturing failures and field returns, coordinating corrective actions across design, validation and manufacturing engineering.
• Own the delivery of manufacturing test fixtures for High Performance Modules and Server Blades, including defining requirements, managing external subcontractors and ensuring fixtures meet quality, cost, schedule and production readiness needs.
• Ensure test solutions are scalable, maintainable and production‑ready, including documentation, training and support processes for factory deployment.
• Support supplier and contract manufacturing engagements as needed, including test station readiness, deployment qualification and ongoing production support.

Candidate Profile

Essential

• Experience developing manufacturing test solutions for high‑performance servers, accelerators (GPU‑class) or comparable large‑scale compute hardware.
• Demonstrated people leadership experience managing a mixed hardware/software engineering team (hiring, coaching, performance management and team development).
• Deep technical understanding across silicon, board and system design sufficient to define effective manufacturing test coverage and guide debug/root‑cause analysis.
• Strong cross‑functional collaboration skills, with experience driving requirements and delivery with internal software/firmware/platform teams to enable testability.
• Hands‑on experience using Linux, OpenBMC and vendor specific test tools, diagnostics and system‑level utilities to test hardware in lab and manufacturing environments.
• Experience with scripting languages such as Python, Bash or similar.

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 process and test optimization.
• Knowledge of open‑source tools commonly used for manufacturing test.

Benefits

In addition to a competitive salary, Graphcore offers flexible working, a generous annual leave policy, private medical insurance and health cash plan, a dental plan, pension (matched up to 5%), life assurance and income protection.
