Staff Electrical Engineer - Low Voltage

*Note: This position requires presence in our San Francisco or San Jose office location 4 days per week; Lambda’s designated work from home day is currently Tuesday.

• Own electrical design standards and reference architectures for low-voltage systems supporting high-density AI infrastructure.
• Lead design from transformer secondary through switchgear, UPS systems, distribution equipment, busway, and rack-level power delivery.
• Develop architectures for 480V and 415V, AC systems serving GPU clusters and supporting infrastructure.
• Define requirements for low-voltage switchgear, switchboards, UPS systems, static transfer switches, PDUs, RPPs, busway, rack PDUs, grounding, metering, and monitoring.
• Model equipment loads, GPU power behavior, transient demand, harmonics, redundancy, capacity, and electrical failure domains.
• Develop and review single-line diagrams, panel schedules, equipment specifications, sequences of operation, and basis-of-design documents.
• Evaluate greenfield, retrofit, and partner-provided designs for reliability, efficiency, maintainability, constructability, cost, and schedule.
• Perform or oversee load-flow, short-circuit, selective-coordination, arc-flash, voltage-drop, and power-quality studies.
• Coordinate electrical requirements across data center facilities, mechanical systems, HPC architecture, hardware engineering, construction, and operations.
• Support equipment selection, factory testing, construction sequencing, commissioning, integrated systems testing, and root-cause investigations.
• Travel to project sites, manufacturers, and partner facilities as needed.
• Have experience designing low-voltage electrical systems for data centers, mission-critical facilities, or large industrial environments.
• Understand low-voltage distribution, UPS topologies, switchgear, busway, grounding, rack-level distribution, and electrical monitoring.
• Understand redundancy models such as N, N+1, 2N, distributed redundant, and catcher architectures.
• Can develop and review single-line diagrams, equipment specifications, coordination studies, and commissioning documentation.
• Have experience with ETAP, SKM, EasyPower, or comparable electrical analysis software.
• Understand applicable electrical and safety requirements, including NEC, NFPA 70E, IEEE, and NETA standards.
• Can translate IT equipment requirements into safe, scalable, and maintainable facility designs.
• Communicate clearly across engineering, construction, operations, vendors, and executive stakeholders.
• Hold a bachelor’s degree in electrical engineering or equivalent practical experience.
• Experience with hyperscale, colocation, HPC, or AI data centers.
• Experience delivering power to high-density GPU racks or liquid-cooled computing infrastructure.
• Familiarity with dynamic GPU loads, power transients, harmonics, rack-level monitoring, or power-capacity optimization.
• Experience supporting factory acceptance testing, commissioning, integrated systems testing, or failure investigations.
• Experience in Low Voltage (400, 800V DC) Converters, distribution and protection devices.
• Experience with PSCAD, other EMT simulation tools or System Stability Analysis
• Professional Engineer licensure or progress toward licensure.
