Coherent Corp. Zurich is a key research and production hub specializing in advanced photonics, engineered materials, and high-power semiconductor laser technologies. Our teams develop and manufacture opto-electronic components and laser diodes for industrial, optical data transmission, life science, and high-precision applications, combining strong in-house R&D with state-of-the-art semiconductor manufacturing in an engineering-led culture.

As a Production Engineer – MOCVD, you will play a key role in supporting the manufacturing of advanced III-V semiconductor laser structures used in cutting-edge photonics technologies.

This is a hands‑on engineering role focused on MOCVD production, process monitoring, semiconductor material characterization, and data‑driven process improvement. Working closely with operations, process engineering, and R&D teams, you will help plan and prepare epitaxial growth processes, analyze production and characterization data, troubleshoot manufacturing issues, and drive improvements in quality, productivity, and process performance across our semiconductor fabrication environment.

• Plan and prepare the growth of GaAs and InP based laser diode structures using MOCVD production equipment
• Coordinate semiconductor material characterization activities and analyze results to support production and process decisions
• Monitor production performance and maintain oversight of manufacturing data to ensure process stability, quality, and productivity
• Drive continuous improvements in production processes with a focus on yield, quality, and operational efficiency
• Support troubleshooting activities through process investigations, data analysis, and collaboration with engineering and service teams
• Participate in the implementation and qualification of new software and hardware solutions to improve fabrication processes

Support the operation and monitoring of MOCVD production tools

• Master’s degree or PhD in Physics, Electrical Engineering, Materials Science, or a comparable technical discipline
• For candidates with a Master’s degree, approximately 2–3 years of relevant industry experience; for candidates with a PhD, approximately 1–2 years of relevant industry experience
• Experience working within a semiconductor production environment is advantageous

• Experience in the characterization of III‑V semiconductor layers
• Basic understanding of semiconductor lasers, including their physics, manufacturing processes, and applications
• Experience with MOCVD, epitaxial growth processes, or related semiconductor manufacturing technologies
• Strong data collection, processing, and analysis skills
• Knowledge of Statistical Process Control (SPC) and process monitoring techniques is advantageous
• Programming experience (e.g. Python, LabVIEW, SQL) is considered a plus
• Results‑oriented personality with initiative and a proactive approach to problem solving
• Ability to work independently while collaborating effectively with production, engineering, and R&D teams
• Strong verbal and written communication skills in German and English

All candidates who wish to apply should submit a CV and cover letter outlining their interest in the position and how their skills and experience align with the requirements of the role.
