Senior System Tests & Diagnostics Engineer

Graphcore, a leading AI hardware company, as a Senior System Tests & Diagnostics Engineer. In this role, you will develop and integrate specialized silicon validation and diagnostics tools for next-generation AI SoCs.

Your work will directly influence hardware quality, silicon bring-up, and long-term platform reliability for future AI infrastructure.

Responsibilities

• You will work closely with Arm engineers to extend existing diagnostics technologies and develop Graphcore-specific capabilities.
• Develop, extend, and integrate specialized silicon validation and diagnostics tools for next-generation AI SoCs.
• Collaborate with hardware architects, firmware engineers, validation engineers, and diagnostics teams to understand new hardware capabilities and translate them into reusable diagnostic software.
• Develop system-level diagnostics and stress tools that integrate with an existing framework to detect data integrity, computational correctness, performance, and reliability issues across various platform components.
• Power transient analysis
• Hardware fault injection methodologies
• Silicon bring-up
• Performance characterization
• Hardware telemetry and observability
• BMC firmware or server management
• Interconnect contention under multi-core load

Requirements

• Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related technical discipline

Strong analytical and debugging skills

• Experience debugging hardware/software interactions across multiple layers of the platform
• Experience with server platforms, embedded systems, or SoC validation

Excellent communication and problem-solving skills

• Experience collaborating across hardware, firmware, software, and validation teams
• Experience developing diagnostics, stress testing, or hardware validation software

Strong software development skills in Python and C/C++

• 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 developing hardware diagnostics, system validation software, firmware validation tools, or low-level systems software
• Strong Linux systems experience
• Memory (DDR/HBM) bandwidth, latency, and NUMA effects
• PCIe/I-O throughput, latency, and multi-device scenarios

Preferred

• Arm-based server platforms
• Silent Data Corruption (SDC) testing
• AI accelerators or high-performance computing systems
• Firmware validation
• RAS (Reliability, Availability, Serviceability) technologies
• Validate across subsystems:
• High-speed I/O validation

Benefits

• Enjoy a flexible work-life balance, private medical insurance, a pension plan, and opportunities for career progression and development.
