Mechanical Engineer

Job Posting Organization:
CERN, the European Organisation for Nuclear Research, is a leading scientific research organization 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 a mission to advance knowledge and understanding of the universe, and it operates in multiple countries, primarily in Europe, with a workforce that includes thousands of employees from diverse backgrounds.

Job Overview:
The Mechanical Engineer position is integral to the Safety Office team within the CERN Research sector and Physics department. The successful candidate will specialize in addressing safety challenges associated with the Neutrino Platform project, both at CERN and in the United States. This role requires a strong focus on mechanical safety, where the engineer will assist in safety risk assessments, ensure compliance with CERN's safety requirements, and implement necessary safety measures. The position also involves regular safety inspections, incident analysis, and collaboration with various teams to support safety during installation and commissioning activities related to the LBNF/DUNE experiment. The engineer will play a crucial role in the logistics and transport of DUNE equipment and will participate in the qualification campaign for the cryostat in the U.S., which includes responsibilities for strain gauge testing and the development of instrumentation plans.

Duties and Responsibilities:
The duties and responsibilities of the Mechanical Engineer include: conducting safety risk assessments for all Neutrino Platform activities at CERN; evaluating compliance with CERN's safety standards; proposing and assisting in the implementation of compensatory safety measures; performing regular safety inspections and ensuring follow-up on recommended actions; coordinating the creation and maintenance of the Neutrino Platform Safety File; conducting incident analyses and following up on recommendations; assisting CERN personnel with safety matters during installation and commissioning activities; interacting with the LBNF DUNE safety organization; reviewing working procedures and performing risk assessments; verifying the implementation of safety measures; providing support for mechanical safety aspects related to logistics and transport; participating in the LBNF DUNE cryostat qualification campaign; developing instrumentation plans; conducting mechanical data processing and analysis; performing finite element analysis (FEA); preparing qualification documentation; and drafting quality assurance and safety justification materials.

Required Qualifications:
Candidates must possess a Master's degree or PhD in mechanical engineering or a related field, or equivalent relevant experience. Extensive experience in mechanical Finite Element static and dynamic analysis is required, with proficiency in ANSYS software being a plus. Proven experience in safety engineering, particularly in risk assessments and equipment conformity in mechanical, cryogenics, and work site fields is essential. Candidates should also have technical competencies in the design and analysis of mechanical structures, occupational safety, and risk management, as well as knowledge of European or US safety standards in mechanical, cryogenics, and occupational safety fields.

Educational Background:
The educational background required for this position includes a Master's degree or PhD in mechanical engineering or a closely related field. Candidates with equivalent relevant experience may also be considered. A strong foundation in mechanical engineering principles, safety engineering, and risk management is crucial for success in this role.

Experience:
Candidates should have extensive experience in mechanical engineering, particularly in the areas of Finite Element analysis and safety engineering. Experience with risk assessments and ensuring equipment conformity in various fields, including mechanical and cryogenics, is necessary. The role demands a solid understanding of safety standards and practices, as well as hands-on experience in conducting safety inspections and incident analyses.

Languages:
Fluency in spoken and written English is mandatory, with a commitment to learn French being a requirement. Proficiency in additional languages may be considered an asset but is not mandatory for this position.

Additional Notes:
This position is a limited duration contract for 5 years, with the possibility of applying for an indefinite position subject to certain conditions. The working hours are set at 40 hours per week, and the role involves working in radiation areas, interventions in underground installations, and may require a valid driving license. The position may also involve shift work, stand-by duty, and work during nights, Sundays, and official holidays as needed. Candidates must be aware of the occupational health risks associated with this position and must obtain medical clearance before a contract offer is confirmed. The job grade for this position is 6-7, and the job reference is EP-DI-SO-2025-124-LD.
