Data Center Infrastructure Electrical Engineer

OpenAI

About the Team OpenAI is building the infrastructure foundation for the next generation of AI. The Data Center Engineering team defines the strategy, reference architectures, technical requirements, and delivery standards for the large-scale data centers that support OpenAI research, products, and infrastructure partners. As a Data Center Infrastructure Electrical Engineer, you will help define, validate, and scale the electrical power systems that support high-density AI compute. You will translate evolving compute requirements into practical facility and rack-power architectures, evaluate new technologies and vendor solutions, and drive technical decisions across design, manufacturing validation, construction, commissioning, deployment, and operations. This role is best suited for a senior hands-on engineer with deep experience in mission-critical power systems, strong judgment under ambiguity, and the ability to connect facility infrastructure, hardware requirements, controls, telemetry, reliability, and operations. About the Role We are seeking a senior electrical infrastructure engineer to lead the development of reliable, scalable, and efficient power architectures for high-density, liquid-cooled AI data centers. The ideal candidate has strong practical experience with critical electrical systems at data centers or comparable industrial scale, including medium-voltage and low-voltage distribution, utility interfaces, backup power, UPS and battery systems, rack power delivery, grounding, protection, controls, and monitoring systems. You should be comfortable moving between long-range architecture, detailed engineering review, lab validation, vendor qualification, field deployment, and operational troubleshooting. Key Responsibilities - Design and optimize electrical topologies and equipment strategies that reduce cost, accelerate schedules, improve efficiency, increase scalability, and maintain high reliability and maintainability. - Review and develop basis-of-design documents, single-line diagrams, equipment specifications, commissioning plans, and power system studies including load flow, short circuit, protection coordination, arc flash, and grid transient compliance. - Lead technical evaluation of equipment vendors, manufacturers, design consultants, commissioning agents, contractors, and test labs. Review submittals, schematics, certifications, quality records, and test reports. - Evaluate AC and DC power distribution options for high-density compute, including rectifier architectures, busway, rack power shelves, power supplies, cable management, redundancy strategies, serviceability, and fault isolation. - Partner with mechanical, cooling, controls, hardware, networking, construction, and operations teams to ensure electrical systems support liquid-cooled GPU rack deployments and reliable facility operation. - Drive FAT, SAT, witness testing, burn-in, reliability testing, interoperability testing, and integrated systems testing for critical infrastructure and rack deployments. - Help guide and operate an R&D program to validate new equipment, rack designs, telemetry, operating envelopes, failure scenarios, and facility-to-hardware interactions. - Define telemetry and controls requirements including metering, waveform capture, breaker and relay status, UPS and battery health, generator status, rack power, CDU status, coolant conditions, alarms, and control states. - Analyze lab data, operational incidents, power quality events, nuisance trips, thermal excursions, controls alarms, and rack-level failures to improve designs, procedures, vendor quality, and reliability models. - Create engineering standards, test procedures, commissioning scripts, operating procedures, decision records, risk registers, and concise executive summaries. - Provide senior technical escalation support during design reviews, construction, manufacturing validation, commissioning, energization, deployment, and operational events. - Raise the technical bar across partner teams in electrical design, safety, testing discipline, documentation quality, reliability, and operational rigors Qualifications - 10+ years of electrical engineering experience in mission-critical facilities such as data centers or comparable critical infrastructure. - Bachelor’s degree in electrical engineering, power systems, or a related discipline. - Strong hands-on experience with MV/LV distribution, transformers, switchgear, switchboards, generators, UPS systems, batteries, PDUs, RPPs, busway, PSUs, grounding, bonding, and protection systems. - Experience producing and reviewing electrical designs, studies, equipment specifications, commissioning plans, test procedures, and acceptance criteria. - Experience leading FWTs, FATs, SATs, integrated systems testing, failure-mode testing, and root-cause investigations. - Strong understanding of codes, standards, utility coordination, safety requirements, and AHJ processes. - Ability to evaluate conflicting technical tradeoffs involving reliability, cost, schedule, constructability, maintainability, and scalability. - Strong written and verbal communication skills with the ability to explain complex issues clearly to technical and non-technical stakeholders. - Comfortable operating in fast-moving environments with incomplete information and changing priorities. Preferred Skills - 15+ years of relevant experience. - Advanced degree in electrical engineering, power systems, or a related discipline. - Professional Engineer license, Chartered Engineer status, or comparable professional certification. - Direct experience with hyperscale data centers, GPU clusters, high-density rack deployments, or liquid-cooled compute environments. - Experience qualifying new electrical products from prototype through certification, manufacturing ramp, deployment, and lifecycle support. - Experience with BMS, EPMS, DCIM, SCADA, PLCs, protective relays, waveform capture, data historians, or reliability analytics platforms. - Experience with modular power systems, rack-level conversion, BESS, HVDC/LVDC, or other advanced power architectures. - Experience managing global, multi-site deployment programs or manufacturing quality programs. - Familiarity with grid constraints, demand response, renewable integration, or low-carbon infrastructure strategies. Work Environment and Travel - This role requires periodic travel to data center campuses, manufacturing partners, equipment suppliers, laboratories, construction sites, and commissioning activities. - The person in this role should be comfortable working in office, lab, manufacturing, construction, and operating data center environments, including environments that require PPE, safety briefings, lockout/tagout discipline, and coordination with site operations. - Work may include time-sensitive technical escalations during commissioning, energization, production deployment, vendor testing, or operational incidents.
