Boom Supersonic is building Superpower, a 42 MW gas turbine designed to power AI data centers with electrical load profiles and operating conditions unlike anything the grid was designed to handle. This role owns the complete electrical architecture and systems that make the engine possible. You will be the principal electrical engineer responsible for the full scope of the engine's electrical system, including power distribution, protection systems, instrumentation, and controls interfaces. This is not a narrow or handoff role—you own the system end-to-end, from architecture and design through schematic capture, hardware bring-up, field validation, and real-time debugging during testing. Key responsibilities include: - Own electrical architecture for major portions of Superpower, spanning from first concept through finalized and validated running hardware - Design and build systems that monitor, protect, and sense the engine under real operating conditions - Partner directly with propulsion, mechanical, controls, and test engineering to integrate electrical systems into a gas turbine platform built from scratch - Manage vendor relationships for critical outsourced hardware components - Lead root-cause investigation when hardware doesn't behave as modeled, in real time during tests - Set technical direction for other engineers working within your electrical system scope This role is for someone who has owned electrical systems end-to-end rather than handing off designs and waiting for test data. You think in systems, moving fluidly between power electronics, protection, instrumentation, and controls because you understand how they interact. You prefer debugging at the test cell to writing white papers. You want to set architecture and defend tradeoffs yourself, not execute someone else's spec. You're energized by ambiguity and write specs when none exist. Requirements: - 7+ years designing and proving electrical systems for power-dense, safety-critical, or first-of-its-kind hardware (grid-scale battery systems like Megapack/Powerpack, motorsport power units such as F1/Formula E/IndyCar/LMDh/LMH, aerospace/satellite power and avionics, or comparable high-performance electrical platforms) - Real depth in at least two of: power distribution, protection systems, instrumentation, high-power electronics, or controls hardware; working fluency across all of them - Track record of taking a system from blank page to tested hardware and owning what happens when it doesn't work the first time - Comfort making difficult decisions with incomplete information and ability to quickly respond when new information invalidates those decisions - Hands-on lab and test experience where you debug with a probe in your hand, not just a datasheet - ITAR requirement: Must be a U.S. citizen, lawful permanent resident, protected individual as defined by 8 U.S.C 1324b(a)(3), or eligible to obtain required authorizations from the U.S. Department of State
