Description

Electrical Engineer — Power Systems (LV & MV) 
Denver, CO Full-time

Boom Supersonic is building Superpower, a 42-megawatt industrial gas turbine derived from supersonic propulsion technology, purpose-built for frontier AI data centers where power demand is scaling faster than the grid can keep up. This role owns the full electrical system of the machine — from 28VDC control circuits through 480VAC skid distribution to 13.8kV generation and delivery — driving every valve, pump, actuator, sensor, and circuit that brings the machine to life and delivering dependable medium-voltage power to islanded critical loads.

There is no inherited architecture. You will reason from first principles, write the playbook, and make design decisions that shape this platform for years. When something doesn't work at first energization, you are on-site tracing signals, reading schematics, and finding the answer.

 
The Challenge

You own the end-to-end electrical design of Superpower — from LV architecture through MV commissioning. No handoffs. No deferring to vendors on hard decisions. You own the outcome.

In practice, that means three phases across both voltage domains:

• Preliminary Design — Define LV and MV architectures, single-line diagrams, interface requirements, protection philosophy, and concept of operations; specify and source long-lead switchgear and generator circuit breakers
• Detailed Design — Produce wiring diagrams, schematics, cable schedules, load lists, I/O lists, protection coordination studies, relay settings, and supporting analyses
• Build & Commission — Own first-article electrical checkout, first energization, relay commissioning, synchronization, load acceptance, step-load testing, and field commissioning
  
  

Requirements

Low Voltage Skills Required

The LV domain spans 480VAC skid-level distribution down to 12–28VDC electronics across every support system on the turbine. Required expertise includes:

• LV power distribution, conversion, control, and protection across 480VAC skid distribution, machine control and actuation, instrumentation, and 12–28VDC electronics
• Cable, harness, junction-box, connector, and control-panel architecture for skid-mounted industrial equipment
• Grounding, bonding, shielding, and EMI/EMC design across power, control, and instrumentation wiring
• Electrical interfaces with the turbine control system — I/O definition, signal types, device power, permissives, and fault feedback
• Motor control systems — VFDs, soft starters, contactors, overload protection, and control relays
• Fuel system electrical integration — valves, actuators, heaters, instrumentation, and gas-conditioning equipment
• Lube oil system electrical integration — pumps, heaters, coolers, level/temperature/pressure instrumentation, and local controls
• Starting system electrical architecture — starter motor interfaces, auxiliaries, permissives, and control circuits
• SCR and emissions system electrical integration — injection systems, heaters, controls, instrumentation, and safety interlocks
• Load bank auxiliary systems — fan power, controls, step-switching interfaces, feedback, and interlocks
• Cooling system electrical integration — radiator fans, cooling tower interfaces, pumps, VFDs, instrumentation, and controls
• Enclosure and balance-of-plant electrical systems — HVAC, lighting, fire detection, suppression interfaces, access control, and safety interlocks

 
Medium Voltage Skills Required

The MV domain is 13.8kV islanded operation at industrial scale — no grid to lean on for frequency reference, fault current, or voltage stability. Required expertise includes:

• Generation, distribution, and protection of all medium-voltage power from generator terminals through switchgear to downstream loads and optional grid interconnect
• Generator excitation, voltage regulation, and interface requirements with the turbine control system
• Switchgear and breaker systems — generator circuit breakers, feeder breakers, and bus-tie configurations
• Protection relay selection, settings, and coordination — differential, overcurrent, ground fault, voltage, and frequency protection
• Fault-current management, interrupting-duty analysis, and equipment rating coordination
• Frequency control, synchronization, and load acceptance for islanded operation
• CT/PT selection, metering, and sensing infrastructure for protection, control, and monitoring
• MV load bank integration, transient response, and step-load testing
• Neutral grounding strategy and ground fault detection
• Arc-flash hazard analysis, electrical safety systems, and interlock design
   

Role Responsibilities

• Own the full-stack electrical architecture of Superpower across both LV and MV domains, from concept through field commissioning
• Produce and maintain all electrical design documentation — single-line diagrams, schematics, wiring diagrams, cable schedules, load lists, I/O lists, protection coordination studies, and relay settings
• Drive design decisions that minimize complexity, reduce part count, and shorten the path from drawing to hardware
• Work directly with mechanical, controls, and systems engineers to define electrical interfaces across all turbine subsystems
• Specify, source, and manage long-lead electrical equipment including switchgear, generator circuit breakers, and MV protection relays
• Lead first-article electrical build, checkout, and troubleshooting on-site
• Own first energization, relay commissioning, synchronization, and step-load testing through endurance testing
• Support field deployment and commissioning at customer sites
• Raise the bar on electrical quality, safety, and reliability across the entire Superpower platform
