Mechanical Engineer

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading scientific research institution established in 195

• It is located in Geneva, Switzerland, and is known for its groundbreaking work in particle physics. CERN employs over 2,500 staff members and collaborates with thousands of scientists from around the world, representing more than 100 nationalities. The organization operates in multiple countries and is dedicated to pushing the frontiers of science and technology, fostering an environment of innovation and collaboration.

Job Overview:
The Mechanical Engineer position at CERN is an exciting opportunity for individuals eager to contribute to the High-Luminosity LHC project, which focuses on the mechanical design and integration of new superconducting transfer lines. The role involves working within an international team to prepare complex cryogenic systems for installation in CERN's underground accelerator galleries. The successful candidate will be responsible for overseeing the project from its design phase through to installation and operation, ensuring that all mechanical aspects are meticulously planned and executed. This position requires a strong background in mechanical engineering, particularly in CAD modeling and mechanical integration, as well as the ability to produce comprehensive technical documentation and coordinate with various stakeholders.

Duties and Responsibilities:
The duties and responsibilities of the Mechanical Engineer include performing CAD modeling and mechanical integration of superconducting transfer lines throughout the project lifecycle, producing technical documentation such as manufacturing and inspection plans, installation procedures, and QA/QC reports. The engineer will also coordinate with stakeholders responsible for neighboring equipment to define assembly, welding, metrology, and leak-tightness procedures. Additionally, the role involves designing bespoke installation tooling in collaboration with technicians, conducting thermal and mechanical analytical and FEM calculations to validate support systems and interface connections, and supporting manufacturing and installation activities with detailed drawings and kinematic simulations.

Required Qualifications:
Candidates must have a professional background in Mechanical Engineering or a related field. They should possess experience in 3D design of complex mechanical assemblies using CATIA V5, familiarity with Product Lifecycle Management (PLM) systems, and the ability to produce 2D manufacturing drawings for metallic components in accordance with ISO standards. Experience in performing thermal and mechanical FEM analyses using ANSYS or similar tools is also required. Additional experience with industrial production of metallic components and knowledge of cryogenic and/or vacuum technologies will be considered an asset.

Educational Background:
The educational background required for this position includes either a Master's degree in Mechanical Engineering or a related field with 2 to 6 years of post-graduation professional experience, or a PhD with no more than 3 years of post-graduation professional experience. Candidates must also be nationals of a CERN Member or Associate Member State and should not have previously held a CERN fellow or graduate contract.

Experience:
The position requires candidates to have a solid level of experience in mechanical engineering, specifically in areas related to CAD modeling, mechanical integration, and FEM analysis. A minimum of 2 years of relevant professional experience is expected for those with a Master's degree, while PhD holders should have some practical experience in the field, ideally not exceeding 3 years post-graduation.

Languages:
Fluency in spoken and written English is mandatory for this position, as it is the working language at CERN. Candidates should also demonstrate a commitment to learning French, which is beneficial for communication within the organization and the local community.

Additional Notes:
This position is fully onsite and involves a contract duration of 24 months, with the possibility of extension up to a maximum of 36 months. The working hours are set at 40 hours per week, and the role may require interventions in underground installations, including work during nights, Sundays, and official holidays as needed. The job reference for this position is TE-MSC-CMI-2026-9-GRAP, and it falls under the field of Mechanical Engineering. The compensation includes a monthly stipend ranging from 6372 to 7004 Swiss Francs, which is tax-free, along with 30 days of paid leave per year, comprehensive health insurance coverage, and various allowances depending on individual circumstances.
