For our head office in Kriessern, we are offering two apprenticeships for metal construction trainees EBA from summer 2026
The apprenticeship lasts four years and offers an interesting field of work involving trailers, superstructures, semi-trailers and special vehicles. Vehicle fitters work with various materials. They shape profiles and tubes into the desired form and weld components together to form complex assemblies.
As a vehicle fitter, you will work with various materials, with a focus on metal. Using plans, you build the basic structure of a vehicle, assemble parts, install the loading areas and equip the vehicle with the necessary accessories. The hydraulics and electrics of a vehicle are also part of the job of a vehicle fitter. A completed apprenticeship offers many opportunities for development and further training in technical professions.
