Integrated Photonics Device Engineer, Zürich (Kreis 11)

Design and simulate passive and active InP photonic integrated circuits at the frontier of electro‑optic performance. You will push the boundaries of high‑speed modulator design, bridge the gap between physics simulation and manufacturable hardware, and own the full loop from concept to tapeout to characterisation.Responsibilities&Qualifications

PhD or equivalent in photonics, electrical engineering, or applied physics with a focus on integrated photonics or optoelectronics Hands‑on photonic integrated circuit design (silicon photonics, InP) Experience designing electro‑optic modulators (EAM or MZM) in III‑V platforms Strong simulation skills: FDTD, EME, or equivalent photonic simulation tools (Lumerical, COMSOL, Tidy3D, or custom)Familiarity with foundry PDKs, DRC/LVS verification, and tapeout submission workflows AI‑assisted design and development workflows — LLM‑aided layout scripting, automated parameter sweeps, and agentic simulation pipelines that close the geometry‑to‑performance loop with minimal manual iterationExperimental characterisation of photonic devices— optical, electro‑optic, and RF Opto‑electronic co‑design pushing the limits of modulator bandwidth Knowledge of DWDM system requirements and datacenter optical interconnects InP foundry tapeout experience with major III‑V MPW platformsBackground in optical frequency combs and optical communication systems What we offer

Competitive salary with meaningful early‑stage equity participation (ESOP) Direct contribution to a world‑class InP photonic platform at an ETH Zürich deep‑tech spinoff Small team, zero bureaucracy — full ownership of your device domain from day one World‑class lab infrastructure and compute resources in ZurichOffice in central Zurich— Europe's deep‑tech capital
