Senior System Tests & Diagnostics Engineer

Responsibilities

• Extend existing Arm diagnostics technologies for Graphcore AI platforms.
• Develop system-level diagnostics and stress-testing software for CPUs, memory, interconnects, PCIe, and other components.
• Build reusable validation utilities and integrate them into existing validation frameworks.
• Create tools that expose intermittent hardware failures, silent data corruption, timing issues, and hardware instability.
• Design configurable, configuration-driven diagnostics for multiple silicon revisions, platforms, and execution environments.
• Automate diagnostic execution across server and rack-scale validation environments.
• Collaborate with hardware architects, firmware engineers, validation engineers, and diagnostics teams to identify missing diagnostics and understand new hardware capabilities.
• Debug low-level interactions among hardware, firmware, operating systems, and device drivers.
• Analyze diagnostic output, improve fault isolation, and develop software for reproducing difficult hardware failures.
• Contribute reusable libraries and utilities that improve productivity across validation teams.

Requirements

• Bachelor’s or master’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline.
• 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 server platform architecture, including CPU, memory, PCIe, storage, networking, firmware, operating systems, and device drivers.
• Experience debugging hardware and software interactions across multiple platform layers.
• Experience developing diagnostics, stress-testing, or hardware validation software.
• Experience with server platforms, embedded systems, or SoC validation.
• Strong analytical, debugging, communication, collaboration, and problem-solving skills.
• Preferred experience with Arm-based server platforms, AI accelerators, high-performance computing systems, silent data corruption testing, hardware stress testing, power transient analysis, fault injection, firmware validation, silicon bring-up, performance characterization, hardware telemetry, BMC firmware, server management, and RAS technologies.
• Preferred experience validating CPU scaling and cache behavior, DDR/HBM memory bandwidth and latency, NUMA effects, interconnect contention, PCIe and high-speed I/O performance, and multi-device scenarios.

Benefits

• Medical, dental, and vision coverage.
• Flexible Spending Accounts and Health Savings Accounts.
• Disability and life insurance.
• 401(k) retirement plan.
• Commuter benefits, wellness services, and an Employee Assistance Programme.
• Flexible working arrangements and reasonable interview adjustments when needed.
• Inclusive equal-opportunity work environment.
