Rack Power Engineer

About the Team

OpenAI’s Hardware organization develops AI-native silicon and system-level solutions for the unique demands of advanced AI workloads. Building on efforts like Jalapeño, the team is developing future generations of AI-native silicon and tightly integrated systems to power the next generation of frontier models. By co-designing chips, systems, tools, and methodologies, the team helps deliver faster, more efficient, and production-ready hardware for OpenAI’s supercomputing platform.

You might thrive in this role if you:

• Have at least 10 years of industry experience in power electronics or power delivery systems, including hands-on design and qualification of high-power rack or data center power systems.
• Have a master’s degree in Electrical Engineering, Power Electronics, a related field, or equivalent practical experience.
• Have strong knowledge of AC/DC rectifiers, power shelves, PSUs, and DC distribution, including three-phase inputs, power conversion topologies, control-loop stability, current sharing, redundancy, protection coordination, and high-current busbars and connectors.
• Have experience defining and qualifying PMCs or related power controllers, including telemetry, fault management, hardware–firmware integration, and interfaces such as PMBus, I²C, CAN, or Ethernet. Understand how rack power controls interact with system power management.
• Have strong laboratory and debugging skills using oscilloscopes, power analyzers, programmable AC sources, electronic loads, and data acquisition systems. Can build automated tests, analyze fleet telemetry with tools such as Python, and drive root-cause investigations through verified corrective actions.
• Have taken power products from requirements through qualification and production with suppliers and cross-functional teams. Bring familiarity with safety, EMC, and reliability qualification; communicate technical trade-offs clearly; and work effectively through ambiguity. Experience with high-density AI racks, OCP power architectures, or energy-storage systems is a plus.

To comply with U.S. export control laws and regulations, candidates for this role may need to meet certain legal status requirements as provided in those laws and regulations.
