Staff Motor Control Software Engineer

Job Title

Staff Engineer

Overview

This staff 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

Position sensorless control of permanent magnet synchronous motors; including advanced inverter pulse-width modulation, position and velocity estimation, current control, fault detection, and efficiency optimization.

Closed loop position control of servo actuation 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

Required

University degree in computer science, computer engineering, or electrical engineering

8+ years of full-time industry experience

Expert knowledge of ac motor control design principles and applications including position sensorless field oriented control, PWM strategies, current control, velocity estimation.

Expert knowledge of MATLAB Simulink model-based design for controls development

Knowledge of real time bare-metal firmware development

Knowledge of object-oriented programming methodology and multi-layered system architectures

Knowledge of multi-threaded systems

Experience with basic electronics debugging tools: oscilloscope, logic analyzer, power analyzer

Experience with modern integrated development environments and debuggers

Basic understanding of version control technologies

Exposure to other languages such as: python, C#, C, SQL

Desired

Master of Science or Doctoral degree in electrical engineering or mechanical engineering focusing on power electronics and/or motor controls
