Electrical Engineer

Aurelius Systems•San Francisco, CA

About The Position

Aurelius Systems is a VC-backed defense tech startup building autonomous, edge-deployed robotics systems using directed energy for counter-UAS. We build laser weapons to shoot down drones. We're a small team of ~10 engineers, former US military operators, and subject matter experts scaling America's directed energy dominance. The first cost effective, reliable and robust laser weapon system. Our namesake isn't an accident. Marcus Aurelius wrote about doing the work in front of you, every day, without excuses. Henry Ford didn't wait for permission to reinvent manufacturing. That's how we operate; small team, unreasonable output, no hiding behind the unachievable. In addition to our San Francisco lab/office, we opened our Detroit manufacturing hub and we field test weekly on our own 400-acre private range. If you are the kind of engineer who'd rather see your work on a range than in a lab, read on. We need an Electrical Engineer who can own a wide surface area of electromechanical hardware. You won't specialize in one subsystem, you'll move across power, embedded control, wire harnesses, and integration work, wherever the team needs horsepower. That means you're soldering prototypes one day, pulling harnesses the next, and helping integrate subsystems on the range the week after. This isn't a narrow role. It's a force multiplier position on a small team building a weapon system from scratch.

Requirements

2–5+ years working across electrical hardware from power, embedded, to systems integration
Hands-on experience with 48V+ systems. You've built and tested high-voltage circuits, not just reviewed drawings
Comfortable with embedded control electronics like microcontrollers, sensing, telemetry, and fault handling
You've designed and fabricated wire harnesses for real systems
Proficient in Altium Designer, SPICE, and MATLAB/Simulink
Broad curiosity. You're as comfortable debugging a harness as reading a power schematic
Where you probably come from: Robotics labs, EV companies, aerospace hardware teams, defense programs, or Formula SAE Electric. You don't have to be a power specialist, but you need to have built real things at voltage.
Not a fit if: Your experience is exclusively low-voltage microcontroller or PCB work, or you've never physically built and tested hardware above 48V.

Nice To Haves

Experience with laser diode driving or directed energy power systems
Background in EMI/EMC design and shielding
Familiarity with MIL-STD standards and ITAR compliance
Experience with long-duration system deployment in harsh environments
Active security clearance or ability to obtain one

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 you build
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
