Senior Motor Control Engineer
San Carlos, CA$180k - $230kFull-timePosted today
About the role
Senior motor control engineer responsible for designing, simulating, tuning, and validating motor control for REVO2 PMSM/BLDC motors across the robot, collaborating with electrical, firmware, and design teams to deliver safe, compliant, high-performance actuation for the NEO humanoid home robot.
Responsibilities
- Own how NEO’s motors turn current into torque. Design, simulate, tune and validate the motor control for the REVO2 family of in-house permanent magnet synchronous motors and for new motors joining the family, in quasi-direct-drive and geared joints across the whole body.
Qualifications
- Bachelor’s degree in Electrical Engineering, Controls, Mechatronics, Robotics or a related field
- 3+ years of industry experience designing and tuning motor control on real hardware
- Shipped motor control: field-oriented control with cascaded current, velocity and position loops for PMSM or BLDC motors that you designed or tuned on hardware that reached production
- Strong command of PMSM modelling in the dq frame, space-vector PWM, inverter non-idealities and voltage limits
- Hands-on motor parameter identification and position sensor calibration (encoder, Hall or resolver, including commutation offset)
- Dynamometer experience measuring torque constant, efficiency, torque ripple and loop response, and turning the data into control changes
- Controller modelling and simulation in MATLAB/Simulink or Python
- Ability to read embedded C/C++ well enough to trace control behavior back to the code
