Principal Execution & QA Validation Engineer

The Validation Execution and Quality team sits within the Validation organisation and is responsible for improving validation effectiveness, test execution efficiency, product quality, and release readiness across Graphcore silicon and platform products.

The team develops validation methodologies, automation frameworks, test execution infrastructure, and quality processes that enable engineering teams to execute validation activities at scale.

Working closely with validation, architecture, firmware, software, systems, and design teams, the group helps ensure products are thoroughly validated before release.

• Define and drive validation strategies for complex silicon, subsystem, and platform technologies, ensuring comprehensive coverage across functional, performance, reliability, and stress testing
• Leverage advanced hardware knowledge to plan, optimize, verify, and test critical electronic systems, including silicon, FPGA-based platforms, test systems, and associated validation infrastructure
• Develop and execute validation plans that ensure products meet quality, reliability, and performance objectives before release
• Create detailed test plans from high-level validation requirements and test cases, ensuring timely execution and high-fidelity results
• Design, develop, and maintain automation frameworks that enable rapid execution of test plans, regression suites, and validation activities
• Lead silicon and platform validation activities from bring-up through product readiness
• Conduct complex analysis of validation results and system behaviour to identify issues and opportunities for improvement
• Collaborate with architecture, design, verification, firmware, software, systems engineering, and validation teams to implement new validation requirements and improve test coverage
• Integrate new validation capabilities, methodologies, and test solutions into existing validation infrastructure to improve productivity, quality, and execution efficiency
• Develop automated data collection, analysis, and reporting solutions to improve engineering visibility and decision-making
• Evaluate complex design features to identify functional, compatibility, integration, and reliability risks
• Investigate and drive resolution of complex validation failures through structured debug and root-cause analysis methodologies
• Assess validation techniques, workflows, and engineering processes, introducing automation and process improvements to maximize productivity
• Support power, performance, and system-level validation activities through development of scalable validation infrastructure and methodologies
• Influence validation roadmaps, infrastructure development, and engineering best practices across the validation organisation
• Act as the final validation authority for assigned areas, ensuring issues are identified and resolved before products reach customers
• Drive continuous improvement initiatives that improve validation quality, execution efficiency, and engineering productivity
• Mentor engineers on validation methodologies, automation frameworks, test execution strategies, and quality practices

• Strong experience in silicon validation, hardware validation, system validation, or related engineering disciplines
• Deep understanding of validation methodologies, test planning, test execution, and quality processes
• Strong experience developing automation frameworks for validation, regression execution, and test orchestration
• Expert-level Python programming skills for automation, data analysis, and infrastructure development
• Strong understanding of hardware systems, silicon bring-up, and validation workflows
• Experience translating high-level requirements into structured validation plans, test cases, and measurable quality outcomes
• Experience analysing validation results and driving root-cause investigations for complex technical issues
• Strong understanding of validation coverage, quality metrics, release readiness criteria, and risk assessment methodologies
• Experience collaborating across architecture, design, verification, firmware, software, systems, and validation teams
• Excellent analytical, diagnostic, and problem-solving skills
• Exceptional communication skills and the ability to influence technical direction across multidisciplinary engineering teams
• Ability to independently lead complex technical initiatives and drive adoption of new validation methodologies and tools

• Experience with post-silicon bring-up and system integration activities
• Experience developing large-scale regression systems and automated test execution infrastructure
• Experience with FPGA-based validation environments
• Experience automating laboratory equipment and validation environments
• Familiarity with CI/CD systems and continuous testing methodologies
