Motor Control Software Engineer at Joby Aviation
San Carlos, CA, US

This engineer will play a key role in a small, fast-moving team and participate in architecture, design, and implementation of motor control systems within our electric-powered, fly-by-wire aircraft. This engineer will work closely with the hardware, mechanical, integration, and flight testing teams to design, develop, test and improve system-level behaviors.

Responsibilities

  • Sensorless control of permanent magnet torque motors; including inverter advanced modulation, position and velocity estimation, current control, fault detection, and efficiency optimization.
  • Closed loop position control of permanent magnet servo systems; including redundant position sensors and multi-phase motors controlled from separate servo drives.
  • Optimization of motor controls using MATLAB Simulink with hand coding capability
  • Assure inverter and motor systems meet performance requirements via controls algorithm development, implementation and testing
  • Oversee dynamometer testing and interpretation of data for controls development, validation and improvement
  • Tuning and calibration of complete systems on dynamometers, on test stands, and on the aircraft.
  • Unit-tests for build environment, sub-system validation testing, integration testing, flight testing, software in the loop testing
