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 frontiers of science and technology, particularly in the field of particle physics, and fosters an environment of innovation and collaboration among a diverse range of professionals.

Job Overview:
The Mechanical Engineer position at CERN involves leading the design, procurement, and on-site implementation of a reinforced passage bridge in UXC55, which is crucial for the High Luminosity (HL) upgrades. The selected candidate will serve as the coordinator" style="border-bottom: 1px dotted #007bff !important;">technical coordinator for the bridge project, ensuring that the design allows for the safe passage of heavy Calorimeter structures. This role encompasses the entire lifecycle of the project, from initial concept and detailed design to procurement, manufacturing oversight, and site installation. Additionally, the engineer will support heavy lifting operations associated with the HL upgrades, which requires a thorough understanding of mechanical and structural engineering principles.

Duties and Responsibilities:
The Mechanical Engineer will be responsible for producing both concept and detailed mechanical/structural designs that ensure the safe passage of heavy Calorimeter structures. This includes conducting load calculations, preparing procurement packages with specifications and drawings, selecting suppliers, and monitoring manufacturing progress to ensure compliance with specifications and schedules. On-site, the engineer will oversee installation activities in UXC55, coordinating with CERN teams and external contractors to ensure that the installation meets all drawings, tolerances, and safety requirements. The engineer will also develop a comprehensive 3D scenario of the HL sequence for the area, perform clash detection, and validate operations and interfaces. Furthermore, the engineer will produce and maintain technical documentation, installation reports, and as-built drawings throughout the project lifecycle.

Required Qualifications:
Candidates must possess the ability to perform load calculations and structural checks, as well as produce design justifications for reinforced structures. Proficiency in 2D/3D CAD software such as AutoCAD, SolidWorks, or CATIA is essential, along with experience in finite-element analysis (FEA) tools for structural validation. The ability to create clear manufacturing drawings and as-built documentation is also required. Candidates should have demonstrated experience in mechanical design, including CAD drawings and FEA simulation, as well as experience in preparing technical specifications, monitoring supplier manufacturing, and conducting quality checks. Familiarity with heavy lifting operations, rigging studies, lifting plans, and vendor coordination is important, as is experience in coordinating meetings and documenting project progress.

Educational Background:
Applicants must have a Bachelor's or Master's degree in mechanical engineering or a related field. Those without a university degree are not eligible, and applicants with a PhD are also not eligible for this position. The educational background should be complemented by a strong foundation in mechanical design principles and practices.

Experience:
Candidates should have a maximum of two years of professional experience since graduation. This experience should be relevant to the field of mechanical engineering, particularly in areas related to structural design and heavy lifting operations. The role is designed for early-career professionals who are looking to develop their skills in a challenging and dynamic environment.

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

Additional Notes:
The position is fully onsite and involves interventions in underground installations. A valid driving license is required. The contract duration 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. The job closing date is January 26, 2026, at 23:59 CET. The compensation includes a monthly stipend ranging from 5196 to 5716 Swiss Francs, which is tax-free, along with 30 days of paid leave per year, comprehensive health insurance coverage, family allowances, a relocation package, and opportunities for on-the-job training and formal training, including language classes.
