About the Role

The team is responsible for developing and applying system-level diagnostics and validation capabilities that ensure the quality and reliability of Graphcore’s AI computing platforms. The role will focus on creating diagnostic and stress-testing capabilities that expose hardware failures, characterize system behavior, and improve platform observability throughout silicon bring-up and validation.

Responsibilities

• Design, develop and extend system-level diagnostic and stress-testing software for Graphcore AI computing platforms.
• Develop diagnostic applications covering processors, memory, interconnects, PCIe, storage, networking and other system components.
• Build reusable validation utilities and libraries that integrate with Graphcore’s system validation infrastructure.
• Develop tools to identify and characterize intermittent hardware failures, including data integrity issues, timing-related failures and system instability.
• Design configurable diagnostic applications capable of supporting multiple silicon revisions, platforms and execution environments.
• Develop automation for executing diagnostics across server and rack-scale validation environments.
• Create configuration-driven diagnostic capabilities that enable scalable parameterization, workload variation and repeatable testing.
• Work with hardware architects and engineering teams to understand new hardware capabilities and identify opportunities for additional diagnostic coverage.
• Collaborate with firmware and validation engineers to improve platform observability and fault isolation.
• Debug complex interactions between hardware, firmware, operating systems and device drivers.
• Analyze diagnostic results, identify failure patterns and develop improved methods for reproducing and isolating system-level issues.
• Develop software and tooling that enables engineering teams to reproduce, investigate and resolve difficult hardware failures efficiently.
• Contribute reusable software components and engineering practices that improve productivity and diagnostic capability across validation teams.
• Provide technical guidance and collaborate across engineering disciplines to solve complex system validation and diagnostic problems.
• Extend existing diagnostics technologies to support new Graphcore hardware.
• Develop new diagnostics tools for emerging hardware capabilities.
• Build reusable software components that integrate seamlessly with the existing validation framework.
• Improve hardware observability and root-cause isolation.
• Detect and characterize intermittent hardware failures that traditional validation techniques cannot expose.
• Deliver configurable diagnostics that scale across multiple platforms and silicon revisions.
• Work effectively across hardware, firmware, validation, and diagnostics teams to continuously improve platform quality.

Requirements

• 5+ years of experience developing hardware diagnostics, system validation software, firmware validation tools, or low-level systems software.
• Strong software development skills in Python and C/C++.
• Strong Linux systems experience.
• Strong understanding of modern server platform architecture, including how CPU, memory, PCIe, storage, networking, firmware, operating system, and device drivers interact within a complete system.
• Experience debugging hardware/software interactions across multiple layers of the platform.
• Experience developing diagnostics, stress testing, or hardware validation software.
• Experience with server platforms, embedded systems, or SoC validation.
• Strong analytical and debugging skills.
• Experience collaborating across hardware, firmware, software, and validation teams.
• Excellent communication and problem-solving skills.
