Develop highly efficient, fault-tolerant propulsion architectures, advanced BLDC and PMSM motor control, power management strategies, and flight-critical propulsion systems that improve endurance, reliability, and autonomous mission performance.
What You'll Do
Motor Control Development
Develop and optimize motor control algorithms for UAV propulsion systems
Design, implement, and tune Field Oriented Control (FOC) and sensorless control strategies
Improve propulsion efficiency, thermal performance, and aircraft endurance
Support development of power management and energy optimization systems
Controls & Software Integration
Collaborate with GNC, Embedded Software, Avionics, and Systems Engineering teams
Integrate propulsion controls with flight controllers and autonomous mission systems
Support development of flight-critical and mission-critical control software
Interface with ESCs, power electronics, batteries, and aircraft power systems
Verification & Flight Testing
Develop Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) test environments
Perform motor characterization, system identification, and control validation
Support bench, ground, and flight testing activities
Analyze flight test data and implement performance improvements
Troubleshoot and resolve propulsion system issues in development and flight environments
Technical Leadership
Lead root-cause investigations for propulsion and power system challenges
