Mechanical Engineer

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading scientific research institution established to probe the fundamental structure of the universe. It employs physicists and engineers who utilize the world's largest and most complex scientific instruments to study the basic constituents of matter. CERN has been at the forefront of particle physics research since its inception, and diversity has been a core value of the organization since its foundation. The organization is committed to employing a diverse workforce, which is essential for its success in scientific endeavors.

Job Overview:
The Mechanical Engineer position at CERN focuses on beam instrumentation for particle accelerators, specifically within the Beam Instrumentation (BI) Group. The role involves studying and developing the next generation of beam instrumentation across the entire accelerator chain. The successful candidate will work in the SY-BI-ML Section, which is responsible for the electro-mechanical design, construction, installation, and maintenance of instrumentation. A significant aspect of this role will be the failure analysis of edge-welded bellows, which are critical components in various equipment. The engineer will be expected to analyze the origins of failures, develop a consolidation plan for future improvements, and establish best practices for designing new instruments. This position offers an opportunity to work in a multicultural and stimulating environment, enhancing skills in precision electro-mechanics design, simulation tools, and research.

Duties and Responsibilities:
The duties and responsibilities of the Mechanical Engineer include:

• Conducting thorough studies to identify the origins of failures in edge-welded bellows.
• Developing a comprehensive consolidation plan for the upcoming years to address identified issues.
• Establishing best practices for the design and implementation of new beam instrumentation.
• Collaborating with a diverse team of professionals in a dynamic research environment.
• Utilizing CAD software, preferably CATIA V5, to create mechanical designs and manufacturing drawings.
• Performing Finite Element Method (FEM) analysis, ideally using ANSYS, to evaluate designs and ensure reliability.
• Engaging in continuous learning and skill development in the field of mechanical engineering and beam instrumentation.

Required Qualifications:
Candidates must possess a Bachelor's or Master's degree in Mechanical Engineering or a related field. They should have a maximum of two years of professional experience since graduation and must be a national of a CERN Member or Associate Member State. Applicants must not have previously held a CERN fellow or graduate contract, and those without a university degree or with a PhD are not eligible for this position. Proficiency in spoken and written English is mandatory, and a commitment to learning French is expected.

Educational Background:
The educational background required for this position includes a Bachelor's or Master's degree in Mechanical Engineering or a closely related field. This educational qualification is essential for understanding the complexities of mechanical design and instrumentation in the context of particle accelerators.

Experience:
The position requires candidates to have a maximum of two years of professional experience in mechanical engineering or a related field. This experience should ideally involve mechanical design and the use of CAD software, as well as familiarity with FEM analysis techniques. Candidates should demonstrate a strong foundation in mechanical engineering principles and practices.

Languages:
Fluency in spoken and written English is mandatory for this position. Additionally, candidates should be committed to learning French, which is considered an asset for effective communication within the multicultural environment at CERN.

Additional Notes:
The contract duration for this position is 24 months, with the possibility of extension up to a maximum of 36 months. The target start date for the role is November 1, 202

• The position involves work in radiation areas and interventions in underground installations, necessitating a valid driving license. The job reference for this position is SY-BI-ML-2025-138-GRAE. The compensation includes a monthly stipend ranging from 5196 to 5716 Swiss Francs (net of tax), comprehensive health coverage for the employee and their family, and various allowances depending on individual circumstances. Employees are entitled to 30 days of paid leave per year and will receive on-the-job training as well as formal training opportunities at CERN, including in-house language courses for English and/or French.
