Develop embedded firmware for the advanced power conversion systems at the heart of our autonomous defense platforms. You will work at the intersection of firmware and power electronics, developing control systems for DC-DC converters, power distribution, and energy management that enable efficient, reliable operation in demanding field environments.

What You’ll Do:

- Design and implement embedded firmware in C/C++ for digital control of power electronics systems, including DC-DC converters, voltage regulation, and power distribution.

- Use simulation tools such as SPICE and MATLAB/Simulink to model, validate, and optimize control systems prior to hardware implementation.

- Partner with electrical engineers to bring up and validate power electronics hardware; perform lab debugging and validation under various load conditions.

- Improve efficiency, stability, and thermal performance of power systems through firmware optimization and continuous iteration.

Must Haves:

- 3+ years embedded firmware development with power electronics systems

- Digital control of DC-DC converters, inverters, or power management systems

- C/C++ for embedded; STM32, TI C2000, or similar microcontrollers

- Control algorithms — PID loops including anti-windup, PWM, phase-shift control

- Simulation tools — SPICE, MATLAB, Simulink

- Partnering with EEs on power electronics bring-up and lab debug under load

Preferred Experience:

- Experience with digital power control loops and compensation techniques.

- Familiarity with high-efficiency power design and EMI considerations.

- Experience with battery systems or energy management systems.

- Background in defense, aerospace, or robotics systems.
