Photonic Design Engineer – Active Components (III-V)

Do you dream of designing the photonic engines at the heart of tomorrow’s communication and quantum systems? At Lightium, we’re developing cutting‑edge photonic integrated circuits (PICs) based on thin‑film lithium niobate (TFLN) — and now we are expanding our platform with integrated III‑V active devices. We are looking for a PIC Design Engineer with deep expertise in modelling and designing active photonic components to join us on this next milestone.

Position Summary

We seek a PIC Designer with a strong focus on III‑V‑based active components, including lasers, semiconductor optical amplifiers (SOAs), and photodetectors. You will lead the simulation, design, and optimisation of these devices, develop compact models for our process design kit (PDK), and support the integration of these elements into complete photonic circuits. Your work will directly shape the active device layer of our hybrid TFLN platform.
