Staff System Tests & Diagnostics Engineer

Responsibilities

• Learn and extend Arm diagnostics tools for Graphcore’s AI platform.
• Develop diagnostic and stress-testing software for CPUs, memory, interconnects, PCIe, and other system components.
• Build reusable validation utilities and libraries within the existing validation framework.
• Create tools that expose intermittent hardware failures, including silent data corruption, timing issues, and instability.
• Design configurable, configuration-driven diagnostics for multiple silicon revisions, platforms, environments, and workload variations.
• Automate diagnostic execution across server and rack-scale validation environments.
• Collaborate with hardware architects, firmware engineers, validation engineers, and diagnostics teams.
• Debug hardware, firmware, operating system, and driver interactions across multiple platform layers.
• Analyze diagnostic output and improve fault isolation and failure-reproduction methodologies.
• Develop software that improves hardware observability and engineering productivity.

Requirements

• Bachelor’s or master’s degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline.
• Strong 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/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, and problem-solving skills.
• Preferred experience with Arm-based server platforms, AI accelerators, high-performance computing, silent data corruption testing, hardware stress testing, power transient analysis, hardware fault injection, firmware validation, silicon bring-up, performance characterization, hardware telemetry, BMC firmware, server management, and RAS technologies.
• Preferred subsystem validation experience covering CPU scaling and cache behavior, DDR/HBM memory, NUMA effects, interconnect contention, PCIe and I/O performance, and high-speed I/O.

Benefits
