Electronics Engineer

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading research institution established in 195

• It is known for its groundbreaking work in the field of particle physics and is home to the world's largest particle accelerator, the Large Hadron Collider. CERN employs over 2,500 staff members and collaborates with thousands of scientists from around the globe, representing more than 100 nationalities. The organization operates in multiple countries, primarily in Europe, and is dedicated to pushing the frontiers of science and technology through innovative research and collaboration.

Job Overview:
The position involves joining CERN's detector R&D program, focusing on advanced optical communication technologies for next-generation particle detectors. The successful candidate will contribute to the development of radiation-tolerant Silicon Photonics components aimed at high-speed data transmission in challenging environments. This role requires hands-on laboratory characterization of Silicon Photonics circuits and the design of innovative photonic devices. The position offers a unique opportunity to work at the intersection of photonics, electronics, and particle detection technologies, contributing to cutting-edge research that shapes our understanding of the universe.

Duties and Responsibilities:
The responsibilities of the Electronics Engineer include contributing to the electro-optical characterization of custom-designed photonic integrated circuits (PICs), validating PIC measurement results against optical simulations, and supporting the integration and evaluation of PICs with particle readout chips (ROCs). The engineer will prototype and demonstrate coarse wavelength-division multiplexing (CWDM) data-transmission systems, characterize and benchmark different data-link architectures, and simulate and design a new generation of test PICs based on measurement results from existing PICs. Additionally, the engineer will present progress at project meetings and conferences and document measurement and simulation results and methods.

Required Qualifications:
Candidates must have proven experience in the design and simulation of photonic components and integrated photonic circuits. Experience in laboratory characterization of optical and photonic components using optical spectrum analyzers (OSAs), tunable lasers, and power meters is essential. The candidate should also have proven experience in high-speed electro-optical measurements utilizing pattern generators, oscilloscopes, error detectors, vector network analyzers (VNAs), and spectrum analyzers. Hands-on experience in the automation of measurement setups for opto-electronic devices and extended experience in the analysis and interpretation of experimental and measurement data are also required.

Educational Background:
The ideal candidate should have a professional background in Electronic Engineering or Physics (or a related field). They should possess either a Master's degree with 2 to 6 years of post-graduation professional experience or a PhD with no more than 3 years of post-graduation professional experience. It is important that candidates have never held a CERN fellow or graduate contract before.

Experience:
Candidates should have a solid level of experience in the relevant fields, with a Master's degree requiring 2 to 6 years of professional experience or a PhD with a maximum of 3 years of experience. This experience should be directly related to the design, simulation, and characterization of photonic components and integrated circuits, as well as high-speed electro-optical measurements.

Languages:
Fluency in spoken and written English is mandatory, and candidates should demonstrate a commitment to learning French, which is considered a valuable asset for the position.

Additional Notes:
The contract duration for this position is 24 months, with the possibility of extension up to a maximum of 36 months. The working hours are set at 40 hours per week, and the position is fully onsite. The target start date is September 1, 202

• The role may involve working during nights, Sundays, and official holidays as required by the needs of the organization. The job reference is EP-ESE-BE-2026-109-GRAP, and the field of work is Electrical or Electronics Engineering. The compensation includes a monthly stipend between 6372-7004 Swiss Francs per month (tax-free), 30 days of paid leave per year plus 2 weeks of annual closure, comprehensive health insurance coverage, family allowances, a relocation package, and opportunities for on-the-job and formal training, including language classes.
