iPronics is looking for a

Photonic IC Designer

to join our Photonics Department and work on large-scale silicon photonics optical circuit switches. The role is mainly on-site at our Valencia office, with some flexibility to work remotely.

Main Responsibilities

Designing and simulating photonic components using Lumerical FDTD, MODE, and other photonic simulation tools.

Using advanced design methods such as inverse design and adjoint optimization.

Optimizing photonic components and conducting reliability analyses under fabrication process variations.

Developing parametric, Python-based layouts of passive and active photonic building blocks (e.g., GDSfactory or KLayout).

Driving research and development of innovative ideas and solutions in photonic component design.

Translating system requirements into photonic IC designs and delivering clear, detailed reports.

Collaborating with cross-functional design groups to ensure measurability and seamless system integration.

Desired Skills & Experience

BSc or MSc degree (PhD preferred) in Telecommunication Engineering, Physics, or a related discipline,



with a focus on Integrated Photonics.

2–3+ years of experience using photonics FDTD simulation tools (e.g., Lumerical, Tidy3D, Comsol).

Strong experience with Python-based layout tools for designing photonic building blocks.

Reliable, proactive, and self-motivated, with excellent communication skills.

Fluent in English (C1 level or higher).

Nice to have

Experience with tape-outs, including design rule checks (DRC) and working with foundry design kits (PDKs).

Experience comparing simulations with measured data from fabricated devices.

Familiarity with advanced optimization frameworks (e.g., optiSLang) or cloud and high-performance computing for running simulations.
