Principal Energy Systems Engineer - High Power Density for Floating & Airborne Sovereign AI Beyond SOF

Beyond SOF • Full-time • Remote • $230k / year • 3h ago

Remote (US preferred) | $230K+ base (equity/OTE avail.)

US Citizen (Preference is currently cleared or prior security clearance-must be clearable)

What You Will Own

Architect and lead end-to-end high-power-density power delivery systems (grid-side and load-side) for 100 kW to multi-MW AI compute platforms in marine and airborne environments.
Design modern solid-state power conversion architectures using latest SiC/GaN components, advanced transformers, rectifiers, and high-voltage medium-voltage distribution that meet or exceed MIL-STD-1399 (shipboard electrical power), MIL-STD-461 (EMC), National Electrical Code, and all relevant high-power engineering standards.
Drive extreme power density and energy storage solutions-ORv3-level packaging, next-gen battery/inverter integration, and custom hyperscale-inspired power delivery networks optimized for weight, thermal, and survivability.
Be the principal technical authority on power systems across floating and airborne platforms-owning requirements, architecture, simulation, validation, and integration from concept through deployment.
Leverage advanced simulation tools (Altair or equivalent) to model, optimize, and de-risk high-power designs under real-world naval/airborne conditions.
Collaborate directly with AI hardware, mechanical, thermal, and mission teams to deliver breakthrough energy density without compromising reliability or safety.

You will not be buried in bureaucracy. You will be the go-to expert shaping the future of sovereign AI power systems for the most demanding operational environments on (and above) the planet.

What We're Looking For

Must-have technical depth

Deep expertise in high-power (100 kW-MW), medium- and high-voltage power supply design using modern solid-state technologies.
Hands-on experience with MIL-STD-1399, MIL-STD-461, NEC, and related shipboard/aerospace power standards.
Proven track record delivering production or flight-qualified power systems in defense, aerospace, or high-performance energy storage environments.
Proficiency with industry-leading simulation tools (Altair preferred).
MS EE (or equivalent) strongly preferred; Professional Engineer (PE) license a significant plus.

Profile we target

Former power systems engineers (i.e. JPL, Philly, Charleston) who understand extreme-environment, high-reliability design.
Grid-side power experts from L3Harris, Raytheon, or similar primes who are creative problem-solvers, not "Mr. No."
Load-side / energy storage leaders from Tesla Energy (Powerwall), hyperscaler custom hardware teams, or top energy storage startups with deep knowledge of latest power density techniques and ORv3-style packaging.
Practical PhDs from programs such as Virginia Tech or Florida State who have real hardware in the field, not just papers.

Desired but not required (experience building this for airborne platforms)

Hands-on experience designing, integrating, or upgrading high-power-density electrical power systems for airborne platforms such as the C-130J Super Hercules (or equivalent military aircraft) with supplemental/additional onboard power generation of 25 kW or greater (e.g., enhanced 60/90 kVA generators and 400 A regulated transformer rectifier units that significantly increase mission electrical capacity).
Deep familiarity with MIL-STD-704 (Aircraft Electric Power Characteristics), including power quality requirements for AC (115/200 V, 400 Hz) and DC systems, voltage/frequency transients, normal/abnormal/emergency operations, and compatibility between aircraft power sources and utilization equipment.
Experience qualifying hardware to RTCA/DO-160 (especially Section 16 - Power Input) along with related aerospace environmental and power testing standards.
Practical knowledge of aircraft power architectures, including generator systems, transformer rectifier units (TRUs), power distribution buses, load analysis, and high-density power conversion optimized for weight, altitude, vibration, and thermal extremes in flight-qualified environments.

Critical intangibles

You thrive in ambiguous, high-stakes, fast-moving environments.
You are excited by the mission: delivering AI superiority when everything else has failed.
You combine first-principles engineering excellence with relentless practicality and creativity.

What We Offer

Compensation: $230,000+ base with significant equity in a well-funded defense-tech company executing at speed. Top-of-market total comp for the right person.
Location: Fully remote (US preferred) with occasional travel to partner sites and test facilities.
Impact: Your work will be deployed on U.S. Navy platforms-and soon airborne platforms. Period.
Team: Elite, mission-driven engineers who move at Beyond SOF speed. No layers, no politics.
Resources: Whatever you need-simulation tools, test hardware, fabrication partners-to deliver at the highest level.

If you are the engineer who can make MW-scale AI compute survive and thrive on a ship in contested waters-or in the air above denied airspace-then we want to talk to you immediately.
