About the role

Actuator Firmware Engineer role at Weave Robotics focused on developing robust, real-time firmware for robot actuators, integrating with hardware, and building low-level control systems for safe and precise motion.

Responsibilities

  • Design, develop, and maintain motor control firmware for early prototypes through production deployment.
  • Develop, implement, and tune hierarchical control systems, including nested feedback control loops.
  • Architect reliable, high-performance firmware that meets the timing, safety, and robustness requirements of production robotic systems.
  • Validate and debug custom motor controllers, sensors, and embedded systems while partnering closely with electrical engineers during board development.
  • Build robust pipelines for encoder calibration, current and voltage sensing, filtering, synchronization, and system characterization.

Qualifications

  • 2+ years developing control software for real-time systems, including firmware architecture, microcontrollers, drivers, and hardware abstraction layers.
  • Deep understanding of embedded systems, firmware engineering, and working with prototype hardware.
  • Proficiency developing embedded software with a deep understanding of real-time constraints and low-level peripherals.
  • Strong understanding of motor control theory with hands-on implementation working with rotary encoders, current sensing, calibration, filtering, and synchronization techniques used for robust feedback control.
  • Experience with embedded communication interfaces such as SPI, I2C, RS-485, CAN/CAN FD and/or EtherCAT.
  • Knowledge of embedded safety mechanisms—including brownout detection, overcurrent protection, watchdogs, and thermal monitoring.
  • Experience with Rust is a plus.
