Embedded Engineer - Motor Control Firmware

• 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

• 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
