Job description

Position: Full Time

Most firmware engineers write code for boards that never leave the bench. This isn't that.

You’ll work at the intersection of firmware and power electronics, developing embedded control systems for the DC-DC converters, power distribution, and energy management at the heart of an autonomous defense platform, systems that have to run efficiently and reliably under field conditions, not just on the bench.

You won’t be handed a spec and a black-boxed board you'll model the control loops in simulation, bring up the hardware yourself, and own the firmware from silicon to system, on a small team where your design decisions ship.

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.

Qualifications and Skills

• 3+ years of experience in embedded firmware development with power electronics systems.
• Experience with digital control of DC-DC converters, inverters, or power management systems; strong understanding of analog and digital power systems.
• Proficiency in C/C++ for embedded systems and experience with microcontrollers such as STM32, TI C2000, or similar.
• Familiarity with implementing control algorithms such as PID loops (including anti-windup), as well as PWM and phase-shift control for power topologies.
• Familiarity with simulation tools including SPICE, MATLAB, and Simulink.

Good to Have

• 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.
• Experience implementing advanced digital control techniques, including PID tuning, anti-windup strategies, and PWM/phase-shift modulation for power systems.
