Senior Embedded Systems Engineer

About the Company

Dexmate is building the foundation for physical AI — a unified platform that combines high-quality robotic hardware with a universal Physical AI OS, making robots as easy to build and deploy as software.

Responsibilities

• Architect and develop production-grade firmware for actuator controllers, sensor interfaces, and communication subsystems
• Own hardware bring-up, including writing low-level peripheral drivers and validating new PCBs
• Implement and optimize motor control algorithms (torque, velocity, and position loops) on bare-metal and RTOS platforms
• Develop and maintain real-time communication stacks including EtherCAT, CAN, SPI, I2C, and UART
• Build and maintain CI/CD pipelines and hardware-in-the-loop (HIL) test infrastructure
• Contribute to firmware safety architecture, including fault detection and watchdog systems
• Participate in hardware design reviews and interpret schematics/datasheets
• Establish firmware standards and coding practices

Requirements

• 5+ years of embedded firmware development experience in robotics, automotive, or industrial/consumer electronics
• Strong C and C++ skills for bare-metal and RTOS environments (ARM Cortex-M, TI C2000, Nordic nRF)
• Hands-on experience with motor control or actuator firmware (FOC, torque control)
• Proficiency with communication protocols (EtherCAT, CAN, SPI, I2C, UART) at the driver level
• Hardware bring-up experience using JTAG, oscilloscopes, and logic analyzers
• Ability to read schematics and PCB layouts

Preferred Qualifications

• Experience scaling firmware from prototype to high-volume production
• Background in functional safety (ISO 26262, IEC 62443)
• Python scripting for test automation and HIL frameworks
• Familiarity with EtherCAT master/slave stack implementation
• Experience with power electronics firmware (BMS, DC-DC converters)
• Experience using AI coding agents to accelerate development
