Staff Electrical Engineer - Medium Voltage

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers. Our customers range from AI researchers to enterprises and hyperscalers. Lambda's mission is to make compute as ubiquitous as electricity and give everyone the power of superintelligence. One person, one GPU. If you'd like to build the world's best AI cloud, join us. *Note: This position requires presence in our San Francisco office location 4 days per week; Lambda’s designated work from home day is currently Tuesday. What You’ll Do

• Own electrical design standards and reference architectures for medium-voltage systems supporting large-scale AI data centers.
• Lead design from utility interconnection through campus distribution and medium-voltage-to-low-voltage transformation.
• Develop and review single-line diagrams, equipment specifications, protection schemes, sequences of operation, and basis-of-design documents.
• Evaluate greenfield, retrofit, and partner-provided designs for capacity, reliability, maintainability, cost, and schedule.
• Perform or oversee load-flow, short-circuit, protective-device coordination, grounding, arc-flash, and power-quality studies.
• Define requirements for substations, transformers, medium-voltage switchgear, protective relays, generators, and associated control systems.
• Work with utilities, engineering partners, equipment manufacturers, construction teams, commissioning agents, and data center operators.
• Support equipment selection, long-lead procurement, factory testing, construction sequencing, commissioning, and integrated systems testing.
• Investigate electrical failures and operational risks, driving corrective actions back into Lambda’s standards and future designs.
• Travel to project sites, manufacturers, and partner facilities as needed. You
• Have experience designing medium-voltage electrical systems for data centers, mission-critical facilities, utilities, or large industrial campuses.
• Understand medium-voltage distribution, transformers, switchgear, generators, grounding, protection, and control systems.
• Can develop and review single-line diagrams, technical specifications, relay philosophies, and electrical study reports.
• Have experience with ETAP, SKM, EasyPower, or comparable electrical analysis software.
• Understand applicable electrical and safety requirements, including NEC, NFPA 70E, IEEE, NETA, and utility standards.
• Can balance reliability, capacity, maintainability, constructability, cost, and delivery schedule.
• Communicate clearly across engineering, construction, operations, vendors, and executive stakeholders.
• Hold a bachelor’s degree in electrical engineering or equivalent practical experience. Nice to Have
• Experience designing hyperscale, colocation, HPC, or AI data center campuses.
• Experience with utility interconnection, large campus substations, or behind-the-meter generation.
• Experience with protective-relay settings, generator paralleling, microgrids, or medium-voltage automation.
• Experience supporting factory acceptance testing, commissioning, integrated systems testing, or failure investigations.
• Experience with PSCAD, other EMT simulation tools or System Stability Analysis
• Professional Engineer licensure or progress toward licensure. Salary Range Information The annual salary range for this position has been set based on market data and other factors.
