Process Engineer Integrated Photonics

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.

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.

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, 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.

• A Process Enthusiast:
  Genuine passion for the processing environment and the "magic" of fabrication.
• A Critical Thinker:
  Open‑minded but analytical, always questioning “how can we make this more stable?”
• Solution‑Oriented:
  When a fabrication run hits a snag, focus on the fix, not the fault.
• A Global Communicator:
  Collaborate in an international environment, proficiency in English (French is a plus).
• Independent yet Integrated:
  Drive own projects while contributing to multidisciplinary R&D and Process team.
