Mechanical Engineer

Job Posting Organization:
CERN, the European Organization for Nuclear Research, was established in 1954 and is one of the world's largest and most respected centers for scientific research. With over 2,500 employees and thousands of scientists from around the globe, CERN operates in 23 member states and collaborates with numerous other countries. The organization is dedicated to pushing the boundaries of knowledge in particle physics and technology, fostering an environment of innovation and collaboration among a diverse range of professionals.

Job Overview:
As a Mechanical Engineer at CERN, you will be an integral part of the multidisciplinary Future Projects team, focusing on research and development for the Future Circular Collider (FCC) components. This role requires you to develop mechanical and mechatronic adjustment and support systems that demand high vibration stability and micrometric precision. You will be responsible for designing and integrating component support structures, adjustment platforms, alignment sensors, and associated infrastructure, all of which contribute to the precise positioning and stability of accelerator components in the frequential domain. Your work will involve gathering design requirements, preparing functional specifications, and conducting vibration and stability analyses. You will also integrate your proposed solutions into accelerator models, ensuring they meet system-level constraints while estimating costs. Collaboration with other teams will be essential as you follow up on the manufacturing, assembly, and qualification of prototypes, and you will be expected to prepare and present technical reports and engineering notes. Additionally, this position includes team supervision responsibilities, making it crucial for you to have strong leadership and communication skills.

Duties and Responsibilities:

• Gather design requirements and prepare functional specifications for mechanical support and alignment solutions.
• Design mechanical support structures and adjustment solutions, including conducting vibration and stability analysis in the frequency domain.
• Integrate proposed solutions into accelerator integration models, ensuring alignment with system-level constraints and providing cost estimates.
• Collaborate closely with other teams during the manufacturing, assembly, and qualification of prototypes.
• Prepare and present detailed technical reports, calculations, and engineering notes.
• Supervise team members and ensure effective collaboration within a multidisciplinary environment.
• Maintain clear and detailed documentation of all engineering processes and decisions.

Required Qualifications:
Candidates must have a professional background in Mechanics, Mechatronics, or a related field. Eligibility criteria include being a national of a CERN Member or Associate Member State. Candidates 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. Additionally, candidates must not have previously held a CERN fellow or graduate contract.

Educational Background:
A Master's degree in Mechanical Engineering, Mechatronics, or a related field is required, with a preference for candidates who have a PhD. The educational background should include a strong foundation in mechanical design, manufacturing processes, and mechatronics systems.

Experience:
Candidates should have experience in mechanical engineering, mechanical design, and the creation of manufacturing drawings. Experience in the design, assembly, and testing of mechatronics systems is essential, as well as familiarity with structure modal analysis using Finite Element Methods. A strong team-oriented attitude and the ability to collaborate effectively within a multidisciplinary environment are also required.

Languages:
Fluency in spoken and written English is mandatory, and candidates should demonstrate a commitment to learning French as a good to have language.

Additional Notes:
The contract duration is 24 months, with a possible extension of up to 36 months. The position requires full-time onsite work, with working hours set at 40 hours per week. The target start date for this position is May 1, 202

• A valid driving license is also required. The job reference for this position is BE-GM-FP-2026-31-GRAP. Compensation includes a monthly stipend between 6372-7004 Swiss Francs (tax-free), 30 days of paid leave per year, comprehensive health insurance coverage, family allowances, a relocation package, and opportunities for on-the-job and formal training, including language classes.
