Introduction to the job: In our high-tech small production runs, single part and prototype production, you will support us in the high-precision manufacture of optical components, assemblies and systems made of glass, glass ceramics and ceramics. Role and responsibilities: As a Process Engineer Cleaning & Etching, you ensure stable, efficient, and future-ready manufacturing processes. Your focus: Process ownership: Independently manage an assigned cleaning or etching process and support additional sub-processes. Monitoring & optimization: Apply Lean and Six Sigma methods (e.g. SPC) to improve yield, cost, and cycle time. Implementation of improvements: Execute simple optimizations independently and support more complex process changes (incl. TGP). Process stability & availability: Ensure process availability and define maintenance strategies. Documentation & training: Create and maintain manufacturing documentation (e.g. AAWs, REZ) and train production teams. NPI & technologies: Introduce new technologies, adapt existing processes, and contribute to NPI, PCCSIM, and ramp-up projects. Risk & collaboration: Contribute to FMEA/ECR, define requirements, and collaborate closely with manufacturing, engineering, and D&E. Education and experience: You hold a degree in a technical or natural science field, or bring a comparable qualification (e.g. Meister with a technical or chemical background). You gained relevant professional experience in a production and technical environment, ideally in cleaning, etching, or comparable surface/chemical processes. You have hands-on experience in cleaning and/or etching processes and understand process parameters, interactions, and tolerances. You apply methods such as Six Sigma, SPC, PDCA, and continuous improvement in practice to stabilize and optimize processes. You contribute to process optimization, manufacturing documentation, and the definition of manufacturing requirements (e.g. specifications). You are familiar with data-driven process control and analysis (e.g. SPC), ideally in interaction with production systems (e.g. MES). You navigate risk and escalation topics confidently (e.g. FMEA) and have a proven ability to collaborate effectively in cross-functional production and engineering environments. You have a strong command of both written and spoken German and English. Skills You structure complex topics clearly and maintain a strong overview. You approach challenges proactively and implement ideas independently. You remain flexible and confident in dynamic and changing environments. You communicate clearly, effectively, and confidently across all levels. You collaborate strongly and actively contribute to team success. You analyze precisely and develop practical, solution-oriented approaches. You take ownership and make decisions that create measurable impact.
