Job summary

Joby Aviation seeks a Software Systems Engineer to design and implement motor control systems for electric aircraft. You will work with hardware, mechanical, integration and flight-testing teams to develop, test and improve system-level behaviors in a fast-paced environment.

The role emphasizes sensor/sensorless motor control, inverter PWM, fault detection, and MATLAB Simulink integration with C/C++ interfaces, with on-site work in San Carlos, CA.

Qualifications

• B.S. in Mechanical Engineering or relevant field and 2+ years of related technical experience (including mechanical, electrical, computer and robotics / mechatronics engineering)
• Experience with actuation systems and/or servo control on safety critical applications
• Experience developing embedded applications in C/C++, MATLAB Simulink model-based design for controls development
• Experience with basic electronics debugging tools: oscilloscope, logic analyzer, power analyzer
• Basic understanding of version control technologies
• Ability to be onsite regularly in San Carlos, CA

Responsibilities

• Sensored and sensorless control of permanent magnet synchronous motors
• Advanced inverter pulse-width modulation, position and velocity estimation, current control and efficiency optimization
• Develop fault detection, isolation, and reconfiguration logic for safety critical systems
• Closed loop position control of simplex and duplex redundant servo actuation systems with redundant position sensors and multi-phase motors controlled from separate inverters
• Optimization of motor controls using MATLAB Simulink
• Develop wrappers and interfaces for the MATLAB Simulink code in C/C++
• Ensure inverter and motor systems meet performance requirements via controls algorithm development, implementation, Simulink simulation and hardware 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, processor/hardware in the loop testing
• Decompose system level requirements to software requirements
• Develop system level actuator models and integrate with inverters and servo controls for holistic system level understanding of performance
