Tasks

About the Job

We are entering a breakthrough phase in high-speed modulation. By integrating electro-optic materials like thin-film lithium niobate onto our SiN platform, we’ve achieved record-breaking results. As our new Process Engineer, you will be the bridge between R&D innovation and production-ready reality. You will:

• Innovate: Lead the development of processes for active material integration on our proprietary SiN platform.
• Execute: Own the Design of Experiments (DoE) within world-class clean-room facilities.
• Scale: Transform prototype fabrication runs into stabilized, high-maturity manufacturing processes.
• Analyze: Use statistical data and physical model fitting to correlate optical and electrical device properties.

Requirements

What You Know

You are a specialist who thrives in the microscopic world, blending a deep understanding of physics with the precision of semiconductor manufacturing.

• Education: A technical degree (MSc or PhD) in Electrical, Chemical, Physical, or Nano Engineering.
• Clean Room Mastery: Several years of hands-on experience with Lithography, Dry Etching, PVD, or CVD.
• Bonding Expertise: Strong, proven experience in wafer or die bonding technologies, this is critical for our active integration goals.
• Data Driven: In-depth knowledge of manufacturing processes with the ability to define and execute complex DoEs and statistical data analysis.
• Maturity Mindset: Experience in increasing process maturity (moving from R&D to Pilot Line/Production) is a significant advantage.

Who You Are

Technology moves fast, but you move faster. We are looking for a teammate who brings more than just a certificate to the table.

• A Process Enthusiast: You don't just work in a clean room; you have a genuine passion for the processing environment and the "magic" of fabrication.
• A Critical Thinker: You are open-minded but analytical, always questioning "how can we make this more stable?"
• Solution-Oriented: When a fabrication run hits a snag, you focus on the fix, not the fault.
• A Global Communicator: You enjoy a collaborative, international environment and possess working proficiency in English (French is a plus).
• Independent yet Integrated: You can drive your own projects while seamlessly contributing to a multidisciplinary R&D and Process team.
