The opportunity
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.
What you'll do
Own rack power architecture and requirements for high-power AI supercomputing: systems, including power budgets, AC input interfaces, DC distribution, redundancy, efficiency, serviceability, and integration with data center infrastructure.
Drive the design and supplier development of power shelves, rectifiers, PSUs,: PMCs, busbars, connectors, and protection circuits. Review electrical designs and control behavior, and evaluate performance, cost, reliability, and availability trade-offs.
Define and execute component, shelf, and rack qualification plans covering: load transients, current sharing, hot-swap, startup and shutdown, redundancy failover, fault protection and recovery, thermal limits, and AC disturbances and ride-through.
Partner with firmware and software teams to define and validate PMC: functionality, telemetry, alarms, power sequencing, power capping, and fault handling. Verify communication interfaces, firmware updates, interoperability, and regression coverage.
Characterize rack power under representative AI workloads. Translate: steady-state demand and fast power excursions into design margins, protection settings, energy-storage needs, and deployment requirements with system and data center teams.
Establish fleet rack power health metrics with operations teams. Analyze: telemetry, event logs, and failure trends to detect degraded power capacity, redundancy loss, current imbalance, and recurring power faults.
What they're looking for
- Lead lab and fleet debugging across power hardware, firmware, and system: interfaces. Reproduce failures, identify root causes with suppliers, validate corrective actions, and feed lessons into designs, qualification tests, and fleet remediation.
- Work with electrical, mechanical, thermal, firmware, manufacturing,: reliability, and data center teams to take rack power systems through prototype builds, qualification, production, and deployment. Drive supplier test reviews, manufacturing test coverage, and closure of power-related issues.
- Evaluate emerging rack power technologies, including higher-voltage DC: distribution and battery or supercapacitor energy storage. Partner with suppliers to qualify viable solutions and with safety and compliance teams to address applicable product requirements.
- 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.
