Senior MV Electrical Architect - Islanded Power Systems

boomsupersonic.com; Centennial, Northern (CO, KY); Hybrid; USD 139,000 - 205,000; Full time

Job summary

Boom Supersonic is building Superpower — a 42‑megawatt industrial gas turbine platform designed to scale for frontier AI data centers. This role owns the 13.8kV medium‑voltage system end to end, from architecture through energization and field commissioning, ensuring protection, stability, and reliable power to critical loads.

You will lead MV design, protection coordination, and interface with turbine control, mechanics, and instrumentation teams to deliver a robust standalone power solution

Qualifications

• 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.

Responsibilities

• 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.
• Leading first energization, relay commissioning, synchronization, load acceptance, and step-load testing.
• Generation, distribution, and protection of all medium‑voltage power from 13.8kV generator terminals through switchgear to loads and optional grid interconnect.
• Protection relay selection, settings, and coordination — differential, overcurrent, ground fault, voltage, and frequency protection.
