Mechanical Engineer

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

• It is known for its groundbreaking work in particle physics, utilizing the world's largest and most complex scientific instruments to explore the fundamental structure of the universe. CERN employs thousands of scientists, engineers, and support staff from over 100 countries, making it a hub for international collaboration in scientific research. The organization operates in multiple countries, primarily in Europe, and is dedicated to advancing our understanding of matter and the laws of nature through innovative research and technology.

Job Overview:
The Mechanical Engineer position at CERN involves integrating into the Safety Office team within the Research sector and Physics department, focusing on the Neutrino Platform project. The role is critical in addressing safety challenges associated with the Neutrino Platform activities both at CERN and in the United States. The successful candidate will be responsible for conducting safety risk assessments, ensuring compliance with CERN's safety standards, and implementing necessary safety measures. This position requires a proactive approach to safety management, including regular inspections and incident analysis, as well as collaboration with various teams to support safety during installation and commissioning activities related to the LBNF/DUNE experiment. The role also includes significant responsibilities in mechanical safety aspects concerning logistics and transport of DUNE equipment, and participation in the qualification campaign for the LBNF DUNE cryostat in the U.S.

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

• Conducting safety risk assessments for all Neutrino Platform activities at CERN, ensuring compliance with safety requirements and proposing compensatory safety measures as necessary.
• Performing regular safety inspections and following up on recommended actions to ensure safety standards are met.
• Coordinating the creation and maintenance of the Neutrino Platform Safety File.
• Analyzing incidents and ensuring the implementation of recommendations.
• Assisting CERN personnel with safety matters during installation and commissioning activities related to the LBNF/DUNE experiment, including reviewing procedures and performing risk assessments.
• Supporting mechanical safety aspects related to the logistics and transport of DUNE equipment.
• Participating in the LBNF DUNE cryostat qualification campaign, focusing on strain gauge testing and developing instrumentation plans, mechanical data processing, finite element analysis, and preparing qualification documentation.

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 analysis, particularly using ANSYS software, is required. Proven experience in safety engineering, including risk assessments and equipment conformity in mechanical and cryogenic fields, is essential. Candidates should also have a strong understanding of occupational safety and risk management, as well as knowledge of European and US safety standards related to mechanical and cryogenic systems.

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 design and analysis, as well as safety engineering principles, 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 mechanical and cryogenic environments is highly valued. Familiarity with safety standards and regulations in both European and US contexts is also important.

Languages:
Fluency in spoken and written English is mandatory, with a commitment to learn French being a significant advantage. This bilingual capability will facilitate effective communication within the diverse international environment at CERN.

Additional Notes:
This position is a limited duration contract for 5 years, with the possibility of applying for an indefinite position under certain conditions. The role requires a commitment to a 40-hour work week, with potential for shift work, stand-by duty, and work during nights, Sundays, and official holidays as needed. The selected candidate must also be prepared for work in radiation areas and underground installations, and must obtain medical clearance due to the occupational health risks associated with the position. The job grade for this position is 6-7, and the job reference is EP-DI-SO-2025-124-LD.
