## About the role

Tonal is looking for a Senior Power Electronics Firmware Engineer to develop the firmware for our motor drive and power systems. That drive generates up to 250 pounds of digital weight, so its firmware defines how Tonal feels to every member. You’ll contribute at every stage, from concept, prototyping, and bring-up through validation and high-volume production. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- 5+ years of embedded firmware development, including 3+ years focused on motor control or power electronics
- Expert C development for real-time, resource-constrained systems, experience in C++ and Python is also valuable
- Experience developing multithreaded firmware on an RTOS, including scheduling, synchronization, and interrupt handling for timing-critical tasks
- Hands-on experience implementing FOC for PMSM/BLDC motors, including current-loop tuning and sensored or sensorless position estimation
- Solid power electronics fundamentals: inverters, DC-DC converters, PWM techniques such as SVPWM, gate drivers, current and voltage sensing, and thermal behavior
- Experience designing discrete-time control loops, filters, and observers, and modeling them in MATLAB/Simulink or Python
