Wohin dieser Kurs führt.
Der Job, um den dieser Kurs gebaut ist, und wie Menschen hineinkommen.
Mechanical Design Engineer
Entwirft mechanische Teile und Produkte und prüft, ob sie halten.
Alle ZukunftsberufeIm Job
- Ein Teil im CAD mit den richtigen Toleranzen modellieren
- Spannung und Wärme prüfen, bevor irgendetwas gebaut wird
- Mit der Werkstatt dafür sorgen, dass sich das Design fertigen lässt
So kommt man hinein
