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.

Qualifications

• 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.

We offer an interesting and diversified opportunity in an internationally minded engineering team of a market-leading high-tech company in the field of high-speed optoelectronic components. You will find a creative and productive work atmosphere in a flexible work environment that shares the desire to succeed and a fascination for technical challenges and technological progress. We provide the following additional benefits:

• Flexible working hours
• 30 vacation days (overtime on top)
• Health benefits package including additional health insurance or fitness program
• Financial support for public transport or parking spot
• Bike lease program
• Bonus and private pension scheme
