This role defines and drives the end-to-end validation architecture across blade-level and rack-level systems. The successful candidate will ensure comprehensive validation coverage across functional, electrical, networking, stress, and thermal domains to enable reliable hyperscale AI infrastructure deployments. 

The Team 

Graphcore is a globally recognised leader in Artificial Intelligence computing systems. The company designs advanced semiconductors and data centre hardware that provide the specialised processing power needed to drive AI innovation, while delivering the efficiency required to support its broader adoption 

The Systems Engineering and Platform Validation team ensures Graphcore’s AI compute platforms are validated and production-ready for hyperscale data center environments. 

The team collaborates closely with silicon enablement, hardware architecture, firmware, system integration, and operations teams to validate complex server and rack-level systems and ensure platform reliability, performance, and scalability. 

Responsibilities and Duties 

• Own the end-to-end validation methodology and technical strategy for AI hardware platforms across blade-level and rack-level systems. 

• Drive validation of rack-scale platforms covering functional, power, cooling, networking fabric, and system reliability. 

• Collaborate with rack validation teams to validate full rack configurations, power distribution, cooling loop integration, and system reliability. 

• Define and lead execution of comprehensive validation test plans for internal teams and ODM validation partners. 

• Ensure validation coverage aligns with architectural, electrical, and mechanical specifications across CPU, GPU, DDR, PCIe, storage, and networking interfaces. 

• Oversee liquid cooling validation including performance, leak detection, and long-term reliability of cooling hardware. 

• Lead debug and issue management across cross-functional engineering teams and external partners. 

• Establish validation dashboards, coverage metrics, and quality indicators to monitor execution progress. 

• Partner with architecture, silicon enablement, firmware, and operations teams to ensure robust system bring-up and production readiness. 

Candidate Profile 

Essential 

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or related discipline. 

• 15+ years of experience in server hardware validation or system engineering. 

• Proven experience validating board, blade, and rack-level server hardware platforms. 

• Strong knowledge of high-speed interfaces such as PCIe, CXL, DDR, NVLink, and Ethernet. 

• Experience developing validation methodologies and large-scale validation test plans. 

• Experience leading debug and failure analysis across complex systems. 

• Experience managing ODM validation programs including test planning and issue tracking. 

• Familiarity with liquid cooling validation and system-level thermal reliability. 

Desirable 

• Experience with ARM-based or x86 server architectures. 

• Background in rack integration testing and hyperscale deployment readiness. 

• Experience with automated validation frameworks and test data analytics. 

• Strong program leadership and cross-functional collaboration skills.
