We're looking for a motivated Robot Simulation Intern (ideally 6 months, mandatory internship) to join our Robotics team in Schönaich (close to Stuttgart), with a flexible start date. If you're excited about building physics-accurate robot models and closing the loop between simulation and real hardware — this is where your work makes a direct impact on humanoid robot development.

• Import and tune robot models for MuJoCo and Isaac Sim — making sure the simulated robot behaves as close to the physical one as possible

• Build ROS2 simulator bridges, including ros2_control sim backends and topic bridging, to connect simulation and real-world control stacks

• Calibrate contact and friction parameters against hardware measurements — the detail work that makes simulation physically meaningful rather than just visually convincing

• Set up RL training environments using Stable Baselines3 or similar frameworks, enabling motion policy evaluation before hardware is available

• Enrolled MSc student in Robotics, Computer Science, or Engineering — with a genuine interest in the intersection of simulation and physical systems

• Strong Python skills, with working knowledge of C++ for performance-critical parts

• You've worked with MuJoCo and/or Isaac Sim (Omniverse/USD) and know what it takes to get a model behaving realistically

• Comfortable with ROS2 basics; experience with simROS2 integration is a plus

• Familiar with RL fundamentals — enough to understand what a training environment needs to actually be useful

• Flexible working hours when life takes unexpected turns

• Company support for gym memberships through Wellpass

• Birthday vouchers

• Drinks and coffee (free of charge, of course)

• Snacks and fruit for all employees, as well as breakfast every Monday

• Regular global team-building events such as boot camps, skiing, and summer BBQs

• An international team with long-term prospects

• Highly competent colleagues who are experts in their field and happy to support you in your learning and growth

• Modern office space

• Our company's WG (upon availability)
