Mechanical Design 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:
As a Mechanical Design Engineer at CERN, you will play a crucial role in the dismantling of the CNGS (CERN Neutrinos to Gran Sasso) and Isolde Beam Dump projects. Your primary responsibilities will include coordinating the transport and handling aspects of these projects, participating in their development, and overseeing the design of installation tooling and machines. You will also be involved in the follow-up of the dismantling and installation phases, working closely with technicians in the field. This position requires a strong background in mechanical engineering, particularly in 3D modeling and mechanical calculations, as well as the ability to work collaboratively in a dynamic environment.

Duties and Responsibilities:
Your duties will include:

• Creating 3D models of the operational environment using Catia software.
• Defining and designing handling tools, and overseeing their construction and delivery.
• Managing project timelines, resources, and the implementation of proposed tooling and methods in collaboration with handling teams.
• Conducting mechanical calculations and preparing detailed calculation notes to be submitted to safety stakeholders.
• Ensuring compliance with safety regulations and standards during all phases of the project.
• Collaborating with multidisciplinary teams to achieve project goals and objectives.
• Participating in project meetings and providing updates on progress and challenges.
• Adapting to changing project requirements and timelines as necessary.

Required Qualifications:
To be eligible for this position, you must be a national of a CERN Member or Associate Member State. You should have a maximum of two years of professional experience since graduation in Mechanical Engineering or a related field. Your highest educational qualification must be either a Bachelor's or Master's degree. It is important to note that applicants without a university degree or those with a PhD are not eligible for this position. Additionally, you should have experience with 3D CAD software such as CATIA, SolidWorks, or Inventor, and be familiar with mechanical calculations using Ansys or other Finite Element Methods.

Educational Background:
Candidates must possess a Bachelor's or Master's degree in Mechanical Engineering or a closely related field. This educational background is essential to ensure that you have the necessary theoretical knowledge and practical skills required for the role. The degree should be from an accredited institution, and relevant coursework or projects related to mechanical design and engineering principles will be advantageous.

Experience:
The position requires candidates to have a maximum of two years of professional experience in the field of Mechanical Engineering or a related discipline. This experience should ideally involve hands-on work with 3D CAD software and mechanical calculations. Candidates who have recently graduated and have relevant internships or project experience may also be considered. It is important that applicants have not previously held a CERN fellow or graduate contract.

Languages:
Proficiency in spoken and written English or French is mandatory for this position. Candidates should demonstrate a commitment to learning the other language if they are not already proficient. This bilingual requirement is essential for effective communication within the diverse teams at CERN and for ensuring safety and compliance in project documentation.

Additional Notes:
The job closing date for applications is 01.03.2026 at 23:59 CET. The contract duration is initially set for 24 months, with the possibility of extension up to a maximum of 36 months. The position requires full-time commitment, with working hours set at 40 hours per week. Candidates should be prepared for the possibility of working in radiation areas, conducting interventions in underground installations, and may need to work during nights, Sundays, and official holidays as required by the organization's needs. A valid driving license is also necessary for this role. Due to the occupational health risks associated with this position, selected candidates must obtain medical clearance before a contract offer is confirmed. The compensation includes a monthly stipend ranging from 5266 to 5793 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.
