You will own the end-to-end loop that takes a policy from simulation onto physical hardware and back again: integrating and maintaining physics simulators, building and operating teleoperation rigs for demonstration collection, bringing up and maintaining real robot platforms, and ensuring our software stack, drivers, calibration pipelines, and data recording infrastructure are reliable enough for both rapid iteration and reproducible experiments. Working knowledge of the ROS/ROS 2 stack, including writing and debugging nodes, working with TF, message types, launch files, and integrating sensors (RGB-D cameras, force/torque sensors, IMUs).
