At LIGENTEC, we aren’t just following the roadmap of the Industrial Revolution 4.0; we are writing it. Based in the vibrant EPFL Innovation Park, we specialize in ultra-low loss Photonic Integrated Circuits (PICs) that power the world’s most advanced Quantum, LiDAR, and Space technologies.
Process Engineer Integrated Photonics
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
* 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.
