About the Role

We are building in-house UAV gimbal systems and are looking for a Motor Control Firmware Engineer to develop the motor-control firmware stack for compact UAV gimbals.

You will work closely with electronics, mechanical, and controls engineers and own the motor-control firmware throughout the product development cycle from initial hardware bring-up and motor calibration to diagnostics, validation, and product qualification.

The role focuses on low-speed, high-precision BLDC motor control for gimbal applications, where smooth and stable motion, accurate rotor-position feedback, low torque ripple, and reliable real-time performance are critical.

Key Responsibilities
● Develop real-time embedded firmware for UAV gimbal motor-control systems
● Design and implement BLDC motor-control algorithms, including commutation strategies, Field-Oriented Control (FOC), and cascaded current, velocity and position control loops
● Implement PWM generation and closed-loop motor control using Hall sensors or magnetic encoders for precise low-speed motion




● Bring up and validate motor controller hardware and firmware, including power stages, gate drivers, current sensing, sensor feedback and motor integration
● Develop firmware features for motor calibration, characterisation and parameter identification, control-loop tuning, telemetry, diagnostics and protection
● Implement communication interfaces between the gimbal, UAV flight-control systems, payload interfaces and ground-control systems
● Support firmware testing, system integration, qualification and UAV flight testing, while maintaining version-controlled firmware and relevant documentation

Required Skills

● Solid proficiency in embedded C/C++ for STM32 or ARM Cortex-M real-time systems, including peripherals such as interrupts, timers, PWM, ADC and DMA.
● Experience with BLDC motor control, including commutation, FOC, current sensing and rotor-position feedback using Hall sensors or magnetic encoders
● Underst
