Optics-Electronics Engineer (BE-GM-FP-2025-64-GRAP)

Job Description

Your responsibilities

As an Optics-Electronics Engineer, you will be a vital member of the Geodetic Metrology Group within the Beams Department (BE) at CERN. This group is responsible for providing metrology and alignment services for components installed across the CERN complex, including accelerators, beam transfer lines, and physics experiments.

In this role, you will contribute to the Future Circular Collider (FCC) project, focusing on the development of new large-scale metrology and high-precision alignment solutions.

Specifically, you will: 

• work with Frequency Scanning Interferometry (FSI) interferometer and sensors, focusing on developing a low-cost, Fourier-based Frequency Scanning Interferometer (FSI). 
• Explore and develop solutions that enable multi-distance measurements of approximately 20 meters with an accuracy of 1 micron.
• Contribute to R&D projects for the Future Circular Collider (FCC), focusing on integrating the vibration-resistant FSI technology into new sensor systems.
• Design and test prototypes to enhance the measurement accuracy, efficiency, and overall capabilities of FSI systems.

Your profile

Skills

• Strong knowledge of electronics, optoelectronics, and optical engineering
• Experience in the design, assembly, and testing of optical and optoelectronic systems with a solid understanding of control systems.
• Proficiency in Python programming.
• Ability to perform precise measurements and conduct inspections using a variety of electronic measurement equipment (e.g., oscilloscopes, spectroscopes, network analyzers) and basic metrology tools (e.g., calipers, micrometers).
• Familiarity with digital signal processing (DSP) algorithms, including FFT, Hilbert transform, and digital filters
• Strong analytical and problem-solving skills
• Experience with additional programming languages such as MATLAB, LabVIEW, and C++ is highly advantageous.
• Spoken and written English, with a commitment to learn French.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in engineer Diploma in Optics, Electronics (or a related field) and have 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.
• You have never had a CERN fellow or graduate contract before.

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.
