Archer Technologies is an aerospace company building all-electric vertical takeoff and landing (eVTOL) aircraft designed to carry four passengers with minimal noise. As a Propulsion Controls Engineer, you will architect and implement advanced control algorithms for electric propulsion systems, choosing between two specialization tracks: motor control (sensorless and observer-based architectures for motor/generator control logic) or power electronics (resonant converter controls and high-performance DC-DC converter topologies).
Key responsibilities include engineering seamless interfaces between flight control computers, power inverters, propulsion controllers, and battery management units. You will develop and troubleshoot safety-critical embedded C/C++ code for real-time aerospace applications, execute rigorous simulations, HIL (hardware-in-the-loop) 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.
You will 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 following DO-178C and DO-254 development standards and uphold meticulous configuration management protocols for all flight-critical software and control assets.
Required: Bachelor's in Electrical, Aerospace, or Computer Engineering (Master's preferred); 2+ years in control systems engineering (electric propulsion, power electronics, motor control, flight controls, EV powertrains, or energy storage); proficiency in embedded C/C++ for real-time safety-critical applications; strong background in either power electronics track (resonant converter control, DC-DC design) or motor control track (FOC, DTC, observers, sensorless control, multi-motor architectures); experience with MATLAB/Simulink and HIL testing; familiarity with microcontrollers and communication protocols (I2C, SPI, CAN).
Bonus qualifications include experience with electric propulsion for aerospace or EVs, battery management systems, high-voltage power electronics, flight-critical system development, aerospace standards, and motor/generator drive system integration.
