Mechanical Engineer for FCC (EP-FCC-2026-51-GRAE)
You will join a team of physicists and engineers working on the development of novel detector concepts for the FCC-ee physics program. You will be the main developer of an electromagnetic calorimeter design based on an innovative technology developed by collaborating institutes.
Your responsibilities
- Interact with physicists at CERN and at collaborating institutes to understand the key figures of merit of a calorimeter design based on the proposed technology.
- Work with CERN engineers and with the FCC Machine-Detector Interface (MDI) group to understand integration constraints related to the experimental cavern and to the collider elements.
- Develop and optimise the detector geometry, producing sufficiently detailed CAD models, in collaboration with the physicist in charge of the detector performance simulations.
- Evaluate construction techniques for the calorimeter mechanical elements, ensuring that both physics performance and structural requirements are met.
- Develop a concept for the overall supporting structure of the calorimeter and its integration within the overall detector mechanics, and validate the concept through structural analysis.
- Oversee the realisation of a demonstrator to validate the design and the selected technical solutions.
Your profile
- Experience with CAD software for mechanical design.
Skills
- Creativity and problem solving skills.
- Ability to work effectively in a multidisciplinary team.
- Spoken and written English, with a commitment to learn French.
Eligibility criteria:
- By the application deadline, you have a maximum of two years of professional experience since graduation in Mechanical Engineering (or a related field) and your highest educational qualification is either a Bachelor's or Master's degree.
- You have never had a CERN fellow or graduate contract before.
- Applicants without University degree are not eligible.
- Applicants with a PhD are not eligible.
