About the role
Embedded Motor Controls Engineer We are looking for an Embedded Motor Controls Engineer to develop the real-time firmware that makes robot actuators precise, responsive and reliable. You will own motor-control implementation, encoder integration, servo tuning, communications and fault handling. This is a hands-on firmware and controls role with substantial time on the bench and on 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 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.
Minimum Qualifications:
Strong embedded C or C++ skills and experience developing real-time firmware on MCUs or DSPs.
Implemented field-oriented control and tuned 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.
Preferred Qualifications:
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
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
