Silicon Photonics Characterisation and Design Engineer (EP-ESE-BE-2026-109-GRAP)
$84,110–$92,453 year
On-site · Genève, Geneva, Switzerland
Job Summary
Silicon Photonics Characterisation and Design Engineer to contribute to electro-optical characterisation of custom-designed photonic integrated circuits (PICs) and their integration with particle readout chips. Responsibilities include validating PIC measurement results against optical simulations, prototyping CWDM data-transmission systems, benchmarking data-link architectures, simulating and designing new PICs from measurement results, and documenting methods. Requirements include a Master's degree in Electronic Engineering or Physics (or related field) with 2–6 years of post-graduation experience (PhD with up to 3 years also acceptable), proven design/simulation experience with photonic components and PICs, hands-on lab work with OSAs, tunable lasers, power meters, high-speed electro-optical measurements (pattern generators, oscilloscopes, VNAs, spectrum analyzers), automation of measurement setups, and strong data analysis. Proficiency in photonic simulation tools (e.g., Ansys Lumerical, Synopsys RSoft), programming in C/Python, experience with Linux, and fluent English (French willingness). CERN-specific eligibility requires nationality of a CERN Member/Associate Member State and no prior CERN fellowship/graduate contract. The role is fully onsite in Geneva, Switzerland, with a 24-month contract (extendable to 36 months), and includes relocation support and a competitive stipend.
