Validation & Testing Intern (m/f/d)

About the role

We’re looking for a motivated Validation & Testing Intern (ideally 6 months, mandatory internship) to join our Validation & Testing team in Schönaich (close to Stuttgart), with a flexible start date. If you want to see how real motion control systems perform outside of simulation — from encoder accuracy to model-based control algorithms on rapid prototyping hardware — this internship puts you right at the heart of our development process. • Perform performance validation and quality control of integrated encoder systems — the measurements that tell us whether a product delivers the precision it promises • Design, build, and operate testbenches for hardware and control algorithm validation, creating the setups that turn open questions into reliable data • Validate model-based control algorithms in simulation and on hardware using rapid control prototyping systems (e.g., Speedgoat), closing the gap between model and real-world behaviour • Support motion control feature development and system-level product validation — making sure new functions work as intended before they reach customers • Analyse test data and document results clearly, providing the basis for development decisions across hardware, firmware, and control teams • Enrolled BSc/MSc student in Mechatronics, Electrical Engineering, Control Engineering, or a related field • Good mechanical intuition and hands-on machining experience — you’re comfortable building and adjusting your own test setups • Basic understanding of control systems, sensors, and embedded systems, and genuine interest in how they perform under real conditions • Experience with MATLAB/Simulink, Python, or similar simulation tools is a plus • You work in a structured, detail-oriented way and enjoy spending time in the lab • 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 • Monthly culinary cultural events • 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 companies WG (upon availablity)
