About the Role

We need an Electrical Engineer to own a wide surface area of electromechanical hardware, moving across power, embedded control, wire harnesses, and integration work wherever the team needs horsepower. This is a force multiplier position on a small team building a weapon system from scratch.

Responsibilities

  • Design and build high-voltage DC/DC converters, rectifiers, inverters, and diode driver electronics (48V+ systems)
  • Architect and validate battery management systems from safe charge/discharge, thermal management, to fault protection for high-voltage battery packs
  • Build ruggedized wire harnesses for high-power laser and motor systems (connector selection, routing, environmental protection)
  • Drive hands-on prototyping, assembly, and field testing of power electronic systems on our range
  • Design embedded control electronics like microcontrollers, FPGAs, sensing, telemetry, and fault handling
  • Perform electrical simulations (SPICE, MATLAB/Simulink) to optimize performance before building
  • Conduct DFM reviews and work directly with fabricators to get designs into production
  • Integrate electronics with mechanical, optical, and robotics subsystems
  • Generate schematics, BOMs, wiring diagrams, and documentation meeting MIL-STD and ITAR requirements

Requirements

  • 2–5+ years working across electrical hardware from power, embedded, to systems integration
  • Hands-on experience with 48V+ systems, including building and testing high-voltage circuits
  • Comfortable with embedded control electronics like microcontrollers, sensing, telemetry, and fault handling
  • Experience designing and fabricating wire harnesses for real systems
  • Experience with multi-layer PCB design, IC selection, and on-board thermal management
  • Proficient in Altium Designer, SPICE, and MATLAB/Simulink
  • Broad curiosity and ability to debug hardware and read schematics
  • Experience likely from Robotics labs, EV companies, aerospace hardware teams, defense programs, or Formula SAE Electric
  • Must have physically built and tested hardware above 48V
