Work on large-scale silicon photonics optical circuit switches using Lumerical FDTD, inverse design, and Python-based layout tools.
About the role
This role involves designing and simulating silicon photonic circuits within the Photonics Department, primarily on-site in Valencia with remote flexibility. Work focuses on large-scale silicon photonics optical circuit switches.
What you'll do
- Design and simulate photonic components using Lumerical FDTD, MODE, and other photonic simulation tools.
- Implement advanced design methods, including inverse design and adjoint optimization.
- Optimize photonic components and conduct reliability analyses under fabrication process variations.
- Develop parametric, Python-based layouts of passive and active photonic building blocks using tools such as GDSfactory or KLayout.
- Translate system requirements into photonic IC designs and deliver detailed reports.
- Collaborate with cross-functional design groups to ensure measurability and system integration.
What you'll need
- BSc or MSc degree (or PhD) in Telecommunication Engineering, Physics, or a related discipline, with a focus on Integrated Photonics.
- 2–3+ years of experience using photonics FDTD simulation tools such as Lumerical, Tidy3D, or Comsol.
- Experience with Python-based layout tools for designing photonic building blocks.
- Professional fluency 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 such as optiSLang, or cloud and high-performance computing for running simulations.
