Power Systems Engineer

Boom Supersonic•Centennial, CO

5h•$107,000 - $187,050

About The Position

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 and no legacy protection scheme to copy. This is the kind of role where that's the point — and we're looking for an engineer who finds genuine energy in the parts of the job nobody has done before.

Requirements

Deep hands-on experience with medium-voltage systems — switchgear, breakers, protective relaying, grounding, and generator integration in industrial or power-generation environments.
Solid understanding of rotating machinery: generator behavior, excitation, AVR systems, synchronization, and transient response under load, faults, and trips.
Experience with protection coordination — relay selection, settings, differential and overcurrent schemes — and the ability to own that work from study through commissioning.
Ability to read and produce clean MV electrical drawings (one-lines, wire diagrams, panel layouts) that can be built and commissioned without ambiguity.
Comfort working across mechanical, controls, and instrumentation teams and translating between them when needed.
U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.

Nice To Haves

A clear point of view on how medium-voltage systems should be built, and you'd rather voice it early than quietly inherit someone else's assumptions.
Enjoys first energization day and is eager to trace issues when something doesn't work.
Comfortable working on a switchgear lineup and at a desk producing coordination studies.
Desire to be the primary driver of system success.

Responsibilities

Lead the end-to-end electrical design of the 13.8kV medium-voltage system on Superpower — from architecture through first energization, endurance testing, and field commissioning.
Define 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.
Produce protection coordination studies, relay settings, and MV electrical drawings through detailed design.
Lead first energization, relay commissioning, synchronization, load acceptance, and step-load testing.
Manage the generation, distribution, and protection of all medium-voltage power, from 13.8kV generator terminals through switchgear to downstream loads and optional grid interconnect.
Oversee generator excitation, voltage regulation, and interface requirements with the turbine control system.
Manage switchgear and breaker systems, including generator circuit breakers, feeder breakers, and bus-tie configurations.
Handle protection relay selection, settings, and coordination — differential, overcurrent, ground fault, voltage, and frequency protection.
Perform fault-current management, interrupting-duty analysis, and equipment rating coordination.
Manage frequency control, synchronization, and load acceptance for islanded operation.
Oversee CT/PT selection, metering, and sensing infrastructure for protection, control, and monitoring.
Manage MV load bank integration, transient response, and step-load testing.
Define the neutral grounding strategy and ground fault detection.
Perform arc-flash hazard analysis, design electrical safety systems, and interlock design.
