Simulation Engineer

Simulation Software Engineer — Humanoid Robotics (Digital Twin)Munich · Full-time · Competitive salary + bonus + VSOPWe're looking for a Simulation Software Engineer to own the digital twin of our partners humanoid platform. This is a software-first role: you'll be building and maintaining the simulation infrastructure that our controls, RL, and hardware teams depend on daily — not just running experiments in someone else's sim.What you'll doOwn and extend our simulation stack (Isaac Sim/Isaac Lab) — build tooling, extensions, and pipelines, not just use them out of the boxBuild and maintain a high-fidelity digital twin of the robot — physics, contact dynamics, actuator behaviour — that our team can trust as a proxy for the real hardwareDevelop software-in-the-loop (SIL) and hardware-in-the-loop (HIL) workflows to validate control software before it ever touches the physical robotOwn system identification: tuning and calibrating simulation models so they track real robot behaviour, closing the sim-to-real gapBuild the software bridge connecting simulation, orchestration, and data pipelines — this is a founding-level infrastructure role, not a downstream user of tools someone else builtWork directly with our controls and robot learning teams to make sure policies trained in sim actually transfer to hardwareWhat we needStrong software engineering fundamentals — C++ and/or Python, comfortable building and maintaining infrastructure, not just scriptsHands-on experience with robotics simulation platforms (Isaac Sim/Isaac Lab, MuJoCo, Gazebo, or similar)Robotics or humanoid robotics experience is required — this is not a role for someone coming purely from game engines, VFX, or non-robotics simulation backgroundsUnderstanding of rigid-body dynamics, contact physics, or controls — enough to reason about why a sim model is or isn't tracking realityComfortable working in a small, fast-moving, early-stage team where you're building the function, not joining an established oneNice to haveExperience with ROS/ROS2 integration into simulation environmentsPrior work on SIL/HIL validation for robotics or safety-critical systemsExposure to RL training pipelines and sim-to-real transfer
