# Embedded Engineer - Motor Control Firmware

- **Company:** Microsoft
- **Location:** Shanghai, VA, United States
- **Experience:** Expert
- **Contract:** Permanent contract
- **Skills:** Application Programming Interfaces (APIs), Computing Platforms, ARM Architecture, Automation of Tests, Computer Programming, Computer Engineering, Datasheets, Software Debugging, Embedded Software, EtherCAT, Firmware, Hardware-In-The-Loop Simulation, Python (Programming Language), MISRA C (C Programming Language), Real Time Systems, Bare Metal
- **Published:** June 25, 2026

## About the Role

* A bare-metal firmware engineer who thinks in microseconds and interrupt priorities
 * Obsessive about determinism, correctness, and clean fault behavior
 * At home on the bench with a logic analyzer and an oscilloscope, * B.Sc. in Electrical Engineering, Computer Engineering, or a related field
 * 8+ years of embedded firmware development in bare-metal, hard real-time systems
 * Strong proficiency in C and STM32 (or equivalent ARM Cortex-M) programming
 * Hands-on experience with motor control firmware (FOC, current/velocity/position loops, encoder interfaces) and/or industrial protocols (EtherCAT, CAN)
 * Excellent debugging skills in both code and hardware environments
 * Comfortable with schematics, datasheets, and bench instrumentation

Advantages:

 * Deep EtherCAT knowledge, including slave stack integration and real-time tuning
 * Experience with servo drives, drone ESCs, or robot joint controllers
 * Exposure to Python for test automation
 * Familiarity with MISRA C or structured safety-oriented code practices
 * Comfortable communicating technical topics in English with international teams

## Description

* Design and develop real-time firmware in C for the STM32-class MCU on the Motor Controller PCB - bare metal, no OS
 * Implement and optimize the control algorithms defined by the Motion Control Engineer: FOC commutation and current/velocity/position loops, with guaranteed loop timing
 * Own calibration routines (encoder offset, current sensing), protections, and fault handling (over-current, over-temperature, encoder loss)
 * Implement the EtherCAT/CAN slave stack and the joint-level communication API exposed to the robot's compute platform
 * Own bootloader, flashing, and fleet firmware-update flow across all joints
 * Work with high-speed peripherals: ADCs, DMA, timers/PWM, interrupts
 * Bring up new board revisions with the electrical engineer; debug with logic analyzers, oscilloscopes, and HIL setups
 * Take full ownership of your code - from bring-up to deployment on the walking robot
