Job summary

Fractile is seeking a hardware test engineer to develop and maintain system-level defect detection tests for servers and rack-based systems, with a focus on PCIe data paths, power delivery and cooling.

You will collaborate with hardware, software, silicon and manufacturing teams to implement fast, deterministic tests, analyze failures, and ensure test coverage aligns with known defect modes and operational needs.

Qualifications

• 3–7 years in system/server hardware test engineering
• Understanding server hardware architectures, PCIe fabrics, power delivery and cooling
• Experience developing or executing hardware defect tests

Responsibilities

• Develop and maintain system-level hardware defect detection tests for servers and rack-based systems
• Implement tests to detect assembly defects, marginal components, damaged hardware, cabling or interconnect issues, 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 and actionable failure output
• 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
• 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
