About The Position

Dexmate is building a robotics platform combining robots with a universal Physical AI OS, with the goal of making robots easier to build and deploy. The Embedded Motor Controls Engineer will develop real-time firmware that makes robot actuators precise, responsive, and reliable. This hands-on firmware and controls role includes substantial bench work and testing on real actuators. The engineer will own motor-control implementation, encoder integration, servo tuning, communications, and fault handling.

Requirements

• Strong embedded C or C++ skills and experience developing real-time firmware on MCUs or DSPs.
• Experience implementing field-oriented control and tuning motor or servo control loops on physical hardware, with measurable performance results.
• Experience with encoder feedback, ADC and PWM timing, interrupts, and bare-metal or RTOS execution.
• Comfort reading schematics and debugging with oscilloscopes, logic analyzers, and hardware debuggers.
• Ability to collaborate across firmware, power electronics, and mechanics.

Nice To Haves

• Experience with TI C2000, STM32, ARM Cortex-M, or similar motor-control platforms.
• Experience with EtherCAT or CAN-based servo networks, torque control, system identification, or friction compensation.
• Experience with HIL, fault injection, production calibration, and Python-based test automation.

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 real hardware.
• Integrate encoders and other feedback sensors, including alignment, calibration, timing, and fault detection.
• Build deterministic command and telemetry interfaces using the selected actuator bus, 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.
