Embedded Motor Controls Engineer, Robotics

About Dexmate

Dexmate is building the foundation for physical AI by combining a new generation of robots with a universal Physical AI OS making robots as easy to build and deploy as software. The company is focused on lowering the barrier to entry in robotics through a plug-and-play platform for developers researchers and enterprises.

The Role

Dexmate is looking for an Embedded Motor Controls Engineer to develop the real-time firmware that makes robot actuators precise responsive and reliable. This is a hands-on firmware and controls role with substantial time spent on the bench and working directly with real actuators.

Responsibilities

- Implement and validate field-oriented control for PMSM or BLDC motors including current-loop timing sensing PWM and parameter calibration.
- Develop torque speed and position control.
- Tune servo response and diagnose instability friction saturation and sensing issues on physical hardware.
- Integrate encoders and other feedback sensors including alignment calibration timing and fault detection.
- Build deterministic command and telemetry interfaces using actuator buses such as CAN CAN FD or EtherCAT.
- Implement current voltage and thermal limits derating and fault recovery in coordination with the drive engineer and actuator lead.
- Develop automated bench and HIL tests with validation engineers.
- Maintain reproducible firmware releases diagnostics and production calibration procedures.
