Power Electronics Engineer

- 3-8+ years in power electronics with direct hardware experience. You've owned designs from schematic to field deployment

- Deep BMS experience from pack architecture, cell balancing, thermal and fault management, to high-voltage integration

- You've designed and validated 48V+ conversion and regulation systems under real operating conditions

- Strong enough to set the technical direction for power systems without a senior engineer above you

- Hands-on wire harness design and fabrication for deployed systems

- Proficient in Altium Designer, SPICE, and MATLAB/Simulink

- Strong background in thermal management, EMI/EMC, and ruggedized system design

Where you probably come from: EV powertrain teams, eVTOL power systems , aerospace power electronics, or defense programs where you owned a power subsystem. If you cut your teeth on Formula SAE Electric and went pro in high-voltage, we definitely want to talk.

Not a fit if: You've only worked within a large power team where someone else set the architecture. We need someone who's been the decision-maker on power systems, not just an executor.

- Experience with laser diode driving or directed energy power systems

- Long-duration system deployment in harsh field environments

- Familiarity with MIL-STD standards and ITAR compliance

- Background in EMI/EMC design and shielding

- Active security clearance or ability to obtain one

BS or MS in Electrical Engineering, Power Electronics, or related field.

What you've built matters more than where you went to school.

- Extreme bias for action. You'd rather build a prototype tomorrow than model it for a month

- Rigorous testing mindset. You characterize your own systems before the field does

- Comfortable with ambiguity and fast, constantly iterating in a startup environment

- Your brain only releases dopamine when you're building

- You debug from first principles, not Stack Overflow

- Clear communicator across mechanical, electrical, optical, and software teams

- Self-directed. You identify what needs to happen next and do it without being told

Why Join Aurelius Systems?

- Build more in 1 month than most engineers build in 1 year. We field test weekly. Your work goes downrange, not into a filing cabinet.

- Career velocity is real. Erick Brito went from Founding Robotics Engineer to Lead in 12 months. At ~10 engineers, there are no layers between you and impact... or between you and your next title.

- Work on a problem that actually matters. Small, cheap drones are changing warfare. Our laser systems are the asymmetric answer.

Think infinite magazine, cost-per-shot near zero, scalable to every base, border, facility, truck and infrastructure.

- Join the densest defense startup ecosystem in the country. California is where the next generation of defense companies are being built. You'll be in the room with the people reshaping how America builds weapons.

How we work: Core hours are Monday-Friday, 9 to 6. When we're sprinting toward a demo or field test, the team ramps up... nights, weekends, whatever it takes to ship.

When the sprint lands, we ramp down. We don't manufacture intensity for show. We go hard when the mission demands it, and we recover when it doesn't.

- Competitive salary + equity

- United Health Care medical, dental, and vision coverage

- Flexible 18 days PTO + 5 sick days

- Travel to field test events and range days

- Covered daily lunches and office snacks + drinks

- E-bike / scooter stipend ( Up to $500)

- Direct access to leadership and real ownership over your work
