We are looking for an engineer who can maintain and extend simulation systems, improve code quality and fidelity, debug simulator-to-robot gaps, and help turn real-world robot behavior into reproducible simulation scenarios.\nYou will work closely with autonomy, infrastructure, and field teams to make simulation a practical part of the development loop: reproduce field issues, improve autonomy, and validate robot behavior before returning to the field.\nWhat You'll Get To Do\nMaintain, refactor, and improve internal robotics simulation tools and infrastructure.\n\nImprove simulation fidelity for autonomy evaluation, including robot behavior, sensor modeling, timing, terrain interaction, and environment representation.\n\nBuild workflows for scenario execution, log replay, regression testing, metrics, and visualization.\n\nDevelop real-to-sim workflows that turn field logs, reconstructed environments, and failure cases into reproducible simulation scenarios.\n\nWork with autonomy and field teams to identify and debug gaps between simulated and real robot behavior.\n\nImprove developer workflows around simulation performance, reproducibility, debugging, and test automation.\n\nContribute to the long-term simulation strategy for legged robots and humanoids operating in complex real-world environments.\n\nWhat You Have\n3+ years of experience developing robotics simulation tools, simulation infrastructure, autonomy evaluation systems, or related robotics software.\n\nStrong software engineering skills in C++ and/or Python.\n\nExperience with simulation platforms such as Isaac Sim, Gazebo, MuJoCo, Unity, Unreal, or custom robotics simulators.\n\nFamiliarity with ROS2 or similar robotics middleware, including sensors, transforms, logs, and timing.\n\nExperience with robot or simulation assets such as URDF, SDF, meshes, dynamics, or sensor models.\n\nAbility to debug simulator-to-robot gaps across sensing, timing, dynamics, and autonomy behavior.\n\nComfortable working across research code, production robotics software, simulation infrastructure, and real-world robot deployment workflows.\n\nWhat Will Set You Apart\nExperience developing simulator plugins, custom sensor models, physics extensions, terrain/contact models, or environment authoring tools.\n\nExperience with large-scale batch simulation, CI-based regression testing, deterministic replay, or scenario evaluation infrastructure.\n\nExperience using real-world robot data to validate, tune, or improve simulation models.\n\nExperience with software-in-the-loop, hardware-in-the-loop, log replay, or simulation correlation.\n\nExperience with legged robots, humanoids, field robotics, or robots operating in unstructured environments.\n\nExperience with Isaac Sim, Omniverse, USD, PhysX, ROS2, Docker, CMake, Bazel, or GitHub Actions.","description_format":"text","description_chars":3043,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics
