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 interconnect issues, cooling faults, etc.
- 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 and actionable failure output suitable for manufacturing and service technicians.
- Develop PCIe defect detection tests to identify lane faults, link degradation, polarity issues, retimer problems, and intermittent connectivity failures.
- Implement stress and soak tests designed to expose latent or marginal hardware issues.
- Debug test failures and hardware issues, performing root-cause analysis and escalating design or process issues as appropriate.
- Analyze factory and field failure data to identify coverage gaps and propose test improvements.
- Support deployment, versioning, and maintenance of test software across factory and service environments.
- Collaborate with software development teams to integrate tests into production system software.
- Collaborate with hardware, manufacturing, service, and reliability teams to ensure tests align with known defect modes and operational needs.
Required Qualifications
- BS or MS in Electronics and Electrical, Computer, or Systems Engineering.
- 3–7 years of experience in system, server, or hardware test engineering, preferably in manufacturing or service environments.
- Solid understanding of server hardware architectures, PCIe fabrics, power delivery, cooling systems, and common failure modes.
- 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 basic use of OpenBMC or Redfish interfaces.
- Strong debug skills and the ability to distinguish test issues from real hardware faults.
- Ability to write clear test code, logs, and documentation for operational use.
Preferred Qualifications
- Experience with AI accelerator, GPU, or high-performance compute servers.
- Exposure to PCIe Gen4/5/6 systems or other high-speed serial interconnects.
- Experience diagnosing intermittent, marginal, or temperature-dependent hardware failures.
- Experience working with liquid-cooled or thermally complex server platforms.
