The opportunity
OpenAI’s Hardware organization develops silicon and system-level solutions designed for the unique demands of advanced AI workloads. The team is responsible for building the next generation of AI-native silicon while working closely with software and research partners to…
What you'll do
Define reliability requirements and targets for PCBAs, trays, systems, and: racks using mission profiles, expected service life, operating environments, duty cycles, and availability goals.
Drive design-for-reliability reviews with electrical, mechanical, and thermal: engineers. Use failure modes and effects analysis (DFMEA or FMEA) and physics of failure to prioritize risks and recommend design improvements. Own component de-rating guidelines and guidance.
Own reliability qualification plans from new product introduction through: production, defining test coverage, representative configurations, sample sizes, stress conditions, duration, pass/fail criteria, and exit evidence at each assembly level.
Develop and execute accelerated life and environmental tests, including: temperature cycling, humidity exposure, power cycling, shock, vibration, and transport testing. Exercise hardware under representative workloads and monitor function and degradation during stress.
Analyze life-test and field data using Weibull and other reliability models,: acceleration models, and confidence intervals. State assumptions, exposure, and uncertainty when estimating failure rates, useful life, or reliability against targets.
Lead failure investigations from symptom reproduction through physical root: cause. Maintain failure reporting, analysis, and corrective-action records, and verify fixes through targeted testing and recurrence monitoring.
What they're looking for
- Review supplier reliability plans and evidence for PCBs, PCBa: components/assemblies, cables, connectors, and cooling components. Identify gaps between component qualification and the stresses encountered in the integrated system or rack.
- Work hands-on with internal and partner labs to develop fixtures,: instrumentation, and test methods. Review sample traceability, test configurations, calibration, raw data, and failure capture, including on-site support at manufacturing partners.
- Partner with manufacturing and quality engineers to establish and validate: reliability screens, burn-in where justified, and ongoing reliability testing. Confirm screening detects relevant defects without consuming unacceptable product life.
- Evaluate reliability risks introduced by assembly and integration: board strain and solder-joint damage, connector mating and retention, cable routing, fastener preload, power connections, and thermal interfaces. Partner with cooling specialists on leak integrity, material compatibility, corrosion, and cooling performance over life.
