About the Role

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers, ranging from AI researchers to enterprises and hyperscalers. Our mission is to make compute as ubiquitous as electricity and give everyone the power of superintelligence.

Responsibilities

  • 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.

Requirements

  • 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.
  • 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.

Skills

  • Hyperscale, colocation, HPC, or AI data centers
  • High-density GPU racks or liquid-cooled computing infrastructure
  • Dynamic GPU loads, power transients, harmonics, rack-level monitoring, or power-capacity optimization
  • Factory acceptance testing, commissioning, integrated systems testing, or failure investigations
  • Low Voltage (400, 800V DC) Converters, distribution and protection devices
  • PSCAD, other EMT simulation tools or System Stability Analysis
  • Professional Engineer licensure or progress toward licensure
