Robotics Embedded Motor Controls Engineer

Dexmate Inc.; United States; On-site; USD 120,000 - 180,000; Full time

Job summary

Dexmate Inc. is seeking an Embedded Motor Controls Engineer to develop real-time firmware for precise, reliable robot actuators. You will own motor-control implementation, encoder integration, and fault handling, with substantial bench time on real hardware.

You will collaborate across firmware, power electronics and mechanics, implementing FOC for PMSM/BLDC, integrating sensors, and building deterministic interfaces (CAN/CAN FD or EtherCAT) for production calibration and testing.

Qualifications

• Strong embedded C/C++ skills and real-time firmware experience on MCUs or DSPs.
• Implemented field-oriented control and tuned motor or servo control loops on physical hardware with measurable results.
• Experience with encoder feedback, ADC and PWM timing, interrupts, and bare-metal or RTOS execution.
• Ability to read schematics and collaborate across firmware, power electronics and mechanics.

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.
