Job description

Digital Power Electronics Firmware Engineer

Location: Austin, Tx (On-site)

Position: Full Time

You’ll be joining a growing autonomous systems company building the next generation of defense platforms.

This role sits right at the intersection of firmware and power electronics, you’ll be the person turning control theory into code that keeps power systems running reliably in tough, real-world field conditions. If you love getting hands‑on with converters, control loops, and hardware bring‑up, this is a great next step.

What You’ll Do

• Design and write embedded firmware (C/C++) for digital control of power electronics like DC-DC converters, voltage regulation, and power distribution.
• Model and validate control systems in SPICE and MATLAB/Simulink before they ever touch real hardware.
• Work side‑by‑side with electrical engineers on hardware bring‑up, lab debugging, and validation across different load conditions.
• Continuously tune and improve firmware for better efficiency, stability, and thermal performance.

Qualifications and Skills

• 3+ years building embedded firmware for power electronics systems.
• Hands‑on experience with digital control of DC-DC converters, inverters, or power management systems.
• Strong C/C++ skills, with experience on microcontrollers like STM32, TI C2000, or similar.
• Comfortable implementing control algorithms such as PID loops (with anti‑windup), PWM, and phase‑shift control.
• Familiarity with SPICE, MATLAB, and Simulink for simulation and validation.

Nice to Have

• Experience with digital power control loops and compensation techniques.
• Knowledge of high‑efficiency power design and EMI considerations.
• Background working with battery systems or energy management.
• Prior experience in defense, aerospace, or robotics.
