Mechanical Design Engineer (m/f/d)

In this role, you advance high-precision opto-mechanical design to support laser-sustained-plasma light sources for semiconductor tooling. You will work within a cross-functional team to deliver robust assemblies, manufacturable drawings, and reliable prototypes, contributing to improved optical performance and reliability. You’ll engage with suppliers to optimize materials, processes, and lead times, while validating designs through simulations and testing. This is a hands-on role with meaningful impact on precision metrology systems used in cutting-edge electronics.
