Electrical Engineer (Medium Voltage)

Electrical Engineer (Medium Voltage) Boom Supersonic is building the breakthrough Overture supersonic airliner and the Superpower industrial gas turbine — machines designed to push the limits of physics, engineering, and industrial ambition. The Superpower platform generates tens of megawatts of electrical power. Turning that power into a reliable, fault-tolerant system requires world-class electrical engineering. That's where you come in. Electrical Engineer — Medium Voltage Systems 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 medium-voltage system that turns shaft power into dependable 13.8kV electrical power, carrying it from generator terminals to islanded load while ensuring the system can protect itself, stay online, and deliver power when it matters. This is medium-voltage electrical engineering at industrial scale. The Superpower platform is designed to operate in arrays that scale to gigawatt-class islanded power. There is no grid to lean on for frequency reference, fault current, or voltage stability. You're not designing a system that parallels an infinite bus and lets the grid handle the hard problems. You're defining from first principles how a standalone 13.8kV machine starts, regulates voltage and frequency, rides through transients, protects itself under fault conditions, and delivers reliable power to critical loads. Grid interconnect is an option for certain applications — but off-grid is the primary design condition, and the harder one. There's no existing system to reference, no senior vendor to defer to, and no legacy protection scheme to copy. The person who thrives in this environment reasons from first-principles physics, owns the outcome, and is energized, not deterred, by the parts of the job nobody has done before. The Challenge You will be responsible for the end-to-end electrical design of the 13.8kV medium-voltage system on the Superpower platform, from architecture through first energization, endurance testing, and field commissioning. No handoffs. No deferring to vendors on hard calls. You own the outcome. In practice, that means: Defining the MV architecture, single-line diagrams, protection philosophy, and concept of operations during preliminary design, including long-lead switchgear and generator circuit breaker specification and sourcing Producing protection coordination studies, relay settings, and MV electrical drawings through detailed design Owning first energization, relay commissioning, synchronization, load acceptance, and step-load testing You own the 13.8kV electrical system end-to-end: Generation, distribution, and protection of all medium-voltage power, from 13.8kV 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, including generator circuit breakers, feeder breakers, and bus-tie configurations Protection relay selection, settings, and coordination, including 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 Compensation P3 Level
