Mechanical Design Intern – Humanoid Robotics (m/f/d)

We're looking for a motivated Mechanical Design Intern (ideally 6 months, mandatory internship) to join our Hardware team in Schönaich (close to Stuttgart), with a flexible start date. If you're excited about precision mechanical design and want to see your drawings go on real prototype hardware delivered to customers — this internship puts you right at the heart of humanoid robot development.

• Create and update detailed joint assembly drawings for robot prototypes — documentation that feeds directly into the build process and goes out with customer deliverables

• Maintain and improve BOMs for actuator assemblies and robot structures, keeping the material record accurate and useful as designs evolve through prototype iterations

• Design actuator brackets, mounting interfaces, and structural elements in SolidWorks — the parts that determine how forces are transferred and how assemblies actually come together

• Run tolerance stack-up analyses for joint fit and assembly, ensuring designs that work in CAD also work in real-world manufacturing and assembly

• Support modular actuator kit design, and collaborate with electrical and software teams to make sure mechanical interfaces make sense across disciplines

• Enrolled BSc/MSc student in Mechanical Engineering or Mechatronics — with an eye for detail and a feel for how things are actually built, not just modelled

• Proficient in SolidWorks or an equivalent parametric CAD tool; comfortable with STEP/IGES file exchange in multi-disciplinary environments where not everyone uses the same software

• Solid grounding in GD&T, DFM principles, and assembly drawing release — you understand that a drawing is a communication tool as much as a geometry record

• You've done tolerance analysis — RSS or worst-case — and understand why it matters for fit, function, and avoiding rework on a prototype build

• A genuine interest in precision robotics; any exposure to gearbox, bearing, or motor integration is a real bonus

• 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)
