Job Description
--------------------------------------

We are looking for a Process Engineer to support the development and optimization of optical coupling processes for advanced optical communication products. A key part of this role is working with automated alignment and assembly equipment (e.g., Ficontec platforms). Therefore, the ideal candidate brings not only process engineering expertise, but also a solid conceptual understanding of programming structured, multi-step automated process flows.


You will work on high-precision coupling steps connecting lasers, modulators, fibers, lenses, and other optical components, while collaborating closely with design, production, and quality teams.

- Develop, optimize, and maintain optical coupling processes for optical communication modules (fiber attach, active/passive alignment, lens/waveguide coupling, etc.).
- Design and refine automated process sequences on alignment equipment (e.g., Ficontec)
- Analyze process data, perform structured experiments, and improve yield, stability, and throughput.
- Support process qualifications, documentation, and smooth transfer into manufacturing.
- Troubleshoot alignment and assembly issues and implement corrective actions.
- Create and maintain technical drawings, process documentation, and work instructions.
- Provide hands-on support during pilot builds, production ramp-up, and continuous improvement activities.




Profil
--------------------------------------
- Degree in Physics, Photonics, Electrical Engineering, Microsystems Engineering, Semiconductor Technology, or similar.
- Several years of experience in optoelectronics, photonics assembly, semiconductor processing, or precision optical assemblies.
- Good understanding of optical coupling and alignment principles.
- Conceptual programming/automation understanding (workflow logic, sequence control, multi-step processes) 
- Basic skills in Python, LabVIEW, PLC, or similar languages/environments used for automation. 
- Good English skills. German is a plus.
- Familiar with working in cross-functional teams.
