Staff Electrical Engineer - Medium Voltage

*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.

• 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.
• 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.
• 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.
