About the role

Senior Robotics Engineer at 9 Mothers Defense, onsite in Austin, TX. Develops the physical control systems for autonomous counter-sUAS interceptor platforms, focusing on high-bandwidth control loops, embedded software, sensor fusion, and real-time hardware interaction.

Responsibilities

  • Design and implement high-bandwidth control loops and advanced control algorithms (e.g., PID control) for vehicle stability and high-speed maneuvers under dynamic load.
  • Write high-quality, efficient code (Rust, C, or C++) to control actuators, motor drivers (via CAN bus), and sensors on RTOS.
  • Integrate and fuse sensor data from cameras and IMUs (EKF/UKF) on embedded systems (e.g., NVIDIA Jetson) for reliable real-time state estimation.
  • Act as the final link in the autonomy chain, translating tracking output from computer vision into reliable motor commands.
  • Define, build, and maintain Python tools for calibration, logging, and CI/CD.

Qualifications

  • Control theory & embedded systems: strong grasp of PID control, motor drivers, CAN bus, and RTOS fundamentals; experience designing control for robotics applications.
  • Programming/frameworks: hands-on experience with embedded robotics systems; proficiency in Rust, C, or C++.
  • Hardware: experience with embedded platforms such as NVIDIA Jetson and camera pipelines; skilled in using scopes, logic/CAN analyzers, and basic rework.
  • U.S. Citizenship and the ability to pass a background check
