Senior Robotics Software Engineer responsible for building motion and trajectory planning systems for robotic manipulators, including kinematics, inverse kinematics, and collision-free path planning. You will develop the driver layer connecting to robot hardware, implement learning-based methods and simulation (reinforcement learning, sim-to-real), and contribute to the full robotics software stack (behaviors, motion planning, world modeling, device control).… You'll write validation suites, collaborate with hardware teams, and mentor engineers while maintaining strong coding and safety practices in a fast-paced startup environment.
