At THEKER, we're taking on one of the greatest challenges of the 21st century: redefining how physical work gets done in the world.

Your role
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. Nothing reaches a client until it has been built, instrumented, and proven on your benches.

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. Much of your work happens at the bench and in the workshop, not on a screen.

As we scale, you move with the hardware into the field.



The first deployments are the most experimental ones, the proof‑of‑concept installations where the design is still being proven in a real plant. You prepare and set up those first systems, validate that they behave the way the bench said they would, and bring back what you learn.

What We’re Looking For

-
- 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.
- Comfort with mechanical measurement and instrumentation. 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 failur
