Software Engineer, Hardware Health

OpenAI is seeking a Software Engineer, Hardware Health to build critical infrastructure that keeps OpenAI’s largest compute clusters healthy and operational at scale. You’ll define and maintain health signals across GPUs, CPUs, networking, and platform infrastructure; build and evolve health checks to detect, remediate, and verify failures at scale; ensure health checks run with minimal latency to maximize uptime; investigate hardware failures across large-scale compute environments; manage node lifecycle workflows (drain, quarantine, repair, RMA, return-to-service); and develop automation and tooling for global cluster management, partnering with workload, reliability, and provider teams to integrate health signals into training and inference systems.
