Duties and Responsibilities- Develop and maintain firmware for humanoid robot controllers, joint actuators, and dexterous hands; contribute to firmware architecture.
- Develop embedded C/C++ firmware, peripheral drivers, and RTOS applications; support board bring-up and hardware validation.
- Implement CAN/CAN FD and Ethernet communication with deterministic timing and synchronized multi-joint actuation.
- Work with controls engineers to implement actuator control loops, sensor integration, and calibration.
- Collaborate with software and controls engineers on firmware interfaces, data models, and SDK integration.
- Implement fault protection, diagnostics, bootloaders, firmware updates, and configuration management.
- Debug hardware and firmware integration issues; develop Python test tools and support regression and hardware-in-the-loop testing.
- Participate in design and code reviews; maintain technical documentation and support firmware releases.
Required Qualifications- B.S., M.S., or Ph.D. in Electrical Engineering, Computer Engineering, Computer Science, or a related field, or equivalent professional experience.
- 1~3 years of professional embedded firmware development experience in industry, including hands-on work with physical hardware.
- Strong C proficiency and working knowledge of C++, real-time systems, interrupts, and concurrency.
