About the Role:

We are seeking a highly skilled Mechatronics or Controls Engineer with deep expertise in actuation systems, low-level motor control, sensor integration and system characterization to help design, prototype, and refine high degree-of-freedom robotic systems. You will be a core contributor in the hardware–software integration loop, ensuring that our systems meet strict performance, safety, and research requirements. This role demands a blend of rigorous engineering skill, hands-on prototyping ability, and close collaboration with AI researchers and software engineers.

Beyond day-to-day hardware and software development, this role also provides exciting avenues to contribute to innovative research projects. Whether you’re passionate about low-level control, state estimation, sensor fusion, or innovative actuation techniques, this role offers opportunities to explore research directions while shaping the core control stack that drives high–degree-of-freedom humanoid robots.

• Key job responsibilities
• Implement and test motor & actuator integration into electromechanical subsystems according to specifications
• Support the development and tuning of control systems, including position, velocity, and torque control loops
• Assist with interfacing control systems with higher-level platforms
• Help maintain motor control board hardware and firmware
• Execute established SysID routines for electromechanical subsystems; implement calibration procedures for sensors and actuators
• Ensure actuator and control systems adhere to safety and robustness requirements
• Collaborate with mechanical, electrical, and AI teams to prototype hardware solutions

About the team
Frontier AI & Robotics (FAR) is the team at Amazon building the next generation of embodied intelligence.

Preferred Qualifications

• Experience with distributed systems at scale
• Experience with high-DOF robotic systems.
• Experience developing inverse kinematics (IK) solvers, kinematic calibration, and running motion simulations (e.g. Mu JoCo, Isaac Sim, MATLAB/Simulink).
• Experience producing models and simulations of complex, high degree-of-freedom dynamic electromechanical systems and actuators
• Ability to spec or design force/torque sensors, or develop algorithms for estimating forces from motor currents for compliance and collision handling.
• Ability to implement and tune inverse kinematics and dynamics algorithms; build and run simulations for system performance validation and motion planning
• Specify, source, or design force–torque sensing capabilities, including developing algorithms for estimating forces from motor currents. Integrate sensing into system-level control strategies for collision response, compliance, and back-drivability
• Proficiency in embedded firmware development for real-time control
• Knowledge of estimating and improving actuator back-drivability
• Knowledge of ROS/ROS 2 or similar robotic middleware.
• Experience with programming languages like C++, Python, MATLAB
• Experience with high-performance, safety-critical mechatronic systems.
