We are looking for a Mechanical Test & Prototyping Engineer to build the physical evidence behind every design decision we make. You own the test benches and the prototypes that tell us whether a new mechanism, gripper, or robotic cell is ready to leave the workshop. You will join the engineering and design team at the point where ideas become hardware.

You build test rigs from scratch, instrument them, and run them until they give you real numbers. You also build the prototypes themselves, working hands‐on from CAD and from conversations with the designers who drew them. The first deployments are the most experimental ones, the proof‐of‐concept installations where the design is still being proven in a real plant.

Engineering degree or Higher Vocational Training in Mechanical, Mechatronics, Industrial, or a related field. Hands‐on experience building and assembling mechanical prototypes or test rigs, with real workshop skills: machining, fitting, fastening, alignment. You can put sensors on a rig, log data, and read what the data is telling you.

Ability to work from technical drawings and CAD models (Fusion 360, SolidWorks, or similar)



and to produce your own when needed. Structured troubleshooting and root cause analysis applied to mechanical failures. Familiarity with data analysis tools for handling test results.

Experience supporting on‐site commissioning or proof‐of‐concept deployments. Design test benches for THEKER's mechanisms, end‐effectors, and robotic cells. Build, assemble, and instrument those benches, and keep them running through long test campaigns.

Run endurance, cycle, and performance tests, then capture and manage the resulting data. Build prototypes from CAD models and the design team's specifications. Prepare and set up the first proof‐of‐concept deployments at client facilities.

Diagnose mechanical failures through structured root cause analysis. Turn test results into structured feedback for the design and engineering teams. Hands‐on technical challenge at our offices, built around a real prototyping and test problem.

Conversation with the engineering and design team.
