Hardware System Test Engineer

Fractile is building silicon, systems and software which will redefine the frontier of AI: running the world’s most advanced models at radically higher speed and lower cost. We have an exceptional team across hardware and software capable of bringing about this change, and we are growing fast to meet demand and deliver our product at scale. We’re looking for an engineer to develop and maintain system-level hardware defect detection tests for an AI accelerator server platform. The role is focused on implementing, executing, and improving tests used in factory assembly and service/repair environments to identify hardware defects quickly and reliably. Work closely with the System Test Engineering Lead to translate defect detection strategy into robust, repeatable test implementations rather than design validation. Key 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.
