Responsibilities

Design and implement motor control algorithms (FOC, trapezoidal, sensorless/sensored BLDC control)

Develop embedded code (typically in C/C++) for motor controllers and ESCs

Select and validate motor drivers, MOSFETs, current sensors, and gate drivers for high-efficiency operation

Design and test ESCs tailored to drone propulsion systems with an emphasis on thermal performance, switching frequency optimization, and EMI reduction

Work with PCB designers to develop compact, thermally-managed layouts for power electronics boards

Integrate motors and controllers into UAV platforms, optimizing thrust-to-weight ratio and dynamic response

Tune PID and control loop parameters for flight stability and minimal latency

Analyze power draw, efficiency curves, and torque-speed characteristics across flight envelopes

Set up and run bench and flight tests to measure thrust, RPM, current draw, and heat dissipation

Use oscilloscopes, current probes, and data loggers to debug and refine system behavior

Perform root cause analysis of electrical or mechanical failures in motor systems and recommend design changes

Work closely with mechanical engineers on propeller sizing, vibration mitigation, and mount design

Coordinate with flight control and embedded systems teams to ensure compatibility between propulsion and control logic

Contribute to motor safety features, redundancy strategies, and startup/shutdown sequencing
