Senior Robotics SWE, System Identification & Modeling

Senior Robotics Software Engineer (System Identification & Modeling) at Nimble, focusing on building core software powering autonomous robots for production environments. Responsibilities include designing and executing system identification experiments for actuators and subsystems, leading kinematic calibration workflows (DH parameters, wheel radius estimation, tool-center-point calibration), building automated calibration and sys-id tooling for rapid re-characterization after mechanical changes, and leading the design and implementation of robot behaviors and end-to-end autonomy across perception, planning, and control. Collaboration with hardware, AI, controls, and infrastructure teams to integrate physics-based models with frontier AI, driving improvements in autonomy quality and arm accuracy. Qualifications emphasize advanced degree in robotics/mechanical/electrical/computer science, 5+ years of production robotics software experience, strong dynamics/controls/system identification skills, experience with motors/actuators/mechatronics, proficiency in Rust/Python/C++, and demonstrated ability to design reliable software, integrate with sensors/embedded systems, and participate in on-call production operations. Nice-to-have items include coursework or research in system identification, nonlinear estimation (EKF, particle filters), sim-to-real (MuJoCo/Drake/Isaac Sim), real-time embedded systems, ROS/ROS2, telemetry pipelines, and safety-critical systems. Compensation ranges from $190k to $250k per year with equity; Nimble offers extensive benefits and a culture focused on legendary impact.
