Propulsion Controls Engineer, Motor / Power Electronics

Key Responsibilities

• Architect, implement, and verify advanced control algorithms for electric propulsion systems focusing on one of the following domains:
• Motor control track: deployment of motor/generator control logic, including sophisticated sensorless and observer-based architectures.
• Power electronics track: engineering of resonant converter controls and high-performance DC-DC converter topologies.
• Engineer seamless interfaces between flight control computers, power inverters, propulsion controllers, and battery management units.
• Develop and troubleshoot safety-critical embedded C/C++ code for real-time aerospace applications.
• Execute rigorous simulations, HIL testing, and iron-bird validation to ensure compliance with strict aerospace performance requirements.
• Design redundant fault detection, isolation, and recovery logic to maintain uncompromising flight safety standards.
• Build and manage complex control architectures, plant models, and HIL environments for motor drives and power conversion hardware.
• Partner with cross-functional teams across airframe, aerodynamics, and structures to optimize the total propulsion system envelope.
• Facilitate flight test programs and prototype vehicle integration through detailed data analysis and system-level debugging.
• Produce comprehensive technical documentation for designs and software iterations following DO-178C and DO-254 development standards.
• Uphold meticulous configuration management protocols for all flight-critical software and control assets.

Required Qualifications

• Bachelor’s degree in Electrical Engineering, Aerospace Engineering, Computer Engineering, or related field (Master’s preferred).
• 2+ years of experience in control systems engineering – electric propulsion, power electronics, motor control, flight controls, EV powertrains, or energy storage systems.
• Proficiency in embedded C/C++ for real-time, safety-critical applications.
• Strong background in at least one of the following:
• Power electronics track: resonant converter control design, DC-DC converter design and implementation.
• Motor control track: advanced motor/generator control algorithms (e.g., FOC, DTC, observers, sensorless control), multi-motor control architectures.
• Experience with simulation and validation tools (MATLAB/Simulink) and HIL testing.
• Familiarity with microcontrollers and communication protocols (I2C, SPI, CAN).
• Detail-oriented with strong analytical and problem-solving skills; comfortable in a fast-paced, collaborative startup environment.

Bonus Qualifications

• Experience with electric propulsion systems for aerospace or EV applications.
• Knowledge of battery management systems, high-voltage power electronics, and high-voltage safety.
• Experience with flight-critical or safety-critical system development, and state machine design.
• Familiarity with aerospace standards (DO-178C, DO-254).
• Experience with system hardware bring-up and integration of motor/generator drive systems.
