Hardware System Test Engineer

Responsibilities

• Develop and maintain system-level hardware defect detection tests for individual servers and rack-based systems
• Implement tests to detect assembly defects, marginal components, damaged hardware, cabling, or cooling faults
• Develop service and field diagnostic tests used for RMA triage, repair validation, and preventative maintenance
• Implement deterministic, fast-running tests with clear pass/fail criteria
• Develop PCIe defect detection tests to identify lane faults, link degradation, and connectivity failures
• Implement stress and soak tests to expose latent hardware issues
• Debug test failures and perform root-cause analysis
• Analyze factory and field failure data to identify coverage gaps
• Collaborate with software, hardware, manufacturing, and reliability teams

Requirements

• 3–7 years of experience in system, server, or hardware test engineering
• Solid understanding of server hardware architectures, PCIe fabrics, power delivery, and cooling systems
• Hands-on experience developing or executing hardware defect detection or diagnostic tests
• Experience working in Linux-based test environments
• Familiarity with BMC-based systems and OpenBMC or Redfish interfaces
• Strong debug skills and ability to write clear test code and documentation

Preferred Qualifications

• Experience with AI accelerator, GPU, or high-performance compute servers
• Exposure to PCIe Gen4/5/6 systems or high-speed serial interconnects
• Experience diagnosing intermittent or temperature-dependent hardware failures
• Experience working with liquid-cooled or thermally complex server platforms
