About The Position

Mainstream Engineering Corporation is seeking a Motor Controls Engineer to lead simulation, software design, prototyping, and validation for next-generation motor control systems. The role involves developing advanced motor control software for thermal systems, combining knowledge of motor control, power electronics, embedded firmware, and model-based design with practical experience developing and testing control algorithms.

Requirements

Bachelor of Science in Computer Engineering, Electrical Engineering, or Computer Science, with a minimum GPA of 3.3.
At least 3 years of experience simulating motor and/or power electronics controls and developing embedded software.
Strong proficiency in embedded C/C++.
Fundamental understanding of electric machine types, including PMSM, BLDC, and IM, and commutation strategies, including FOC, DTC, SVPWM, and six-step.
Understanding of MCUs, switching devices such as MOSFETs, IGBTs, SiC, and GaN, gate drivers, current and voltage sensing, and ADC synchronization.
Proficiency in software debugging and use of standard hardware debugging tools, such as oscilloscopes, logic analyzers, and dynamometers.
U.S. citizenship required due to U.S. Government ITAR program restrictions.

Nice To Haves

Master's or Ph.D. degree.
Familiarity with thermal/HVAC systems.
Experience developing and following DO-178 documentation and processes.
Experience with TI C2000 or STM32 microcontroller families.
Experience with additional programming languages such as C#, Python, or assembly, and GUI design.
Understanding of hardware components, hardware and PCB debugging, sensors and actuators, and common communication protocols.

Responsibilities

Design, build, and optimize high-fidelity three-phase inverter and electric motor models in PLECS or MATLAB/Simulink to validate motor controls, electrical parameters, device behavior, and thermal performance.
Evaluate and select commutation topologies, including FOC, DTC, SVPWM, and six-step, for motors and systems.
Implement multivariable control loops for speed, torque, and position tracking, and verify safe operation of electric machines and components in simulation.
Develop sensorless and/or sensored control algorithms, state estimators, and observers to track rotor position and velocity.
Translate simulated controls into embedded C/C++ software and validate the software.
Develop software requirements and maintain bidirectional traceability among system requirements, code, and test cases.
Maintain version control and configuration management baselines in alignment with appropriate standards.
Design and execute functional and/or automated testing to demonstrate compliance with software requirements.
Assist with hardware bring-up, hardware/software debugging, analysis of steady-state and transient test results, and dynamometer testing.
Work with electric machine designers to support optimized motor parameters.
Partner with hardware and power electronics engineers to design, test, and optimize motor drive hardware and thermal performance.
Collaborate with software engineers to integrate core motor control algorithms into the main embedded software framework.
