À propos
Hardware System Test Engineer Fractile is building silicon, systems and software that 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.
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.
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.
