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

About the Company
- Aurelius Systems is a VC backed defense tech startup building autonomous, edge deployed directed energy systems for counter-UAS.
- We build laser weapons to shoot down drones.
- We're a small team of engineers, former US military operators, and subject matter experts scaling America's directed energy dominance.
- We build the first cost effective, reliable and robust laser weapon system.
- We operate with a small team, unreasonable output, and no hiding behind the unachievable.
- We have a San Francisco lab, a Detroit manufacturing hub, and field test weekly on our own 400-acre private range.
Equal Opportunity
- This role requires access to export-controlled information or items that require "U.S. Person" status. As defined by U.S. law, individuals who are any one of the following are considered to be a "U.S. Person": (1) U.S. citizens, (2) legal permanent residents (a.k.a. green card holders), and (3) certain protected classes of asylees and refugees, as defined in 8 U.S.C. 1324b(a)(3).
