Mechanical Engineer for Vacuum

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 centres for scientific research. With a mission to push the frontiers of science and technology, CERN employs over 2,500 staff members and collaborates with thousands of scientists from around the globe. The organization operates in multiple countries and is known for its groundbreaking work in particle physics, contributing to our understanding of the universe. Diversity and inclusion are core values at CERN, fostering an environment where innovation thrives and every contribution is valued.

Job Overview:
As a Mechanical Engineer for Vacuum at CERN, you will play a crucial role in the development of vacuum systems for the future accelerator, FCC-ee. This position involves selecting, characterizing, and validating materials and processes for ultra-high vacuum components. You will be responsible for defining samples and prototypes, overseeing their production and procurement, and conducting testing and validation. The role requires collaboration with a dynamic team dedicated to the FCC-ee study and regular communication with CERN-wide services and external partners. Your expertise will directly contribute to the advancement of vacuum technologies in a cutting-edge research environment.

Duties and Responsibilities:

• Actively participate in the development of FCC-ee vacuum systems, focusing on materials and process selection, characterization, and validation.
• Contribute to the internalization and in-house development of key manufacturing technologies for large component production.
• Collaborate with a dynamic team dedicated to the FCC-ee study, ensuring effective communication and teamwork.
• Regularly communicate with CERN-wide services and external companies or institutes to facilitate project progress.
• Define and oversee the production of samples and prototypes for vacuum components.
• Conduct testing and validation of materials and processes to ensure compliance with ultra-high vacuum standards.
• Engage in the fabrication of mechanical parts using CNC machines and CAM software.
• Produce samples for materials characterization, including microscopic observations.
• Design mechanical parts using CAD programs, with a preference for CATIA. 1
• Maintain a commitment to learning and improving language skills in English and French.

Required Qualifications:
Candidates must be nationals of a CERN Member or Associate Member State and possess a professional background in Mechanical/Materials & Process Engineering or a related field. The ideal candidate will have either a Master's degree with 2 to 6 years of post-graduation professional experience or a PhD with no more than 3 years of post-graduation professional experience. Additionally, candidates must not have previously held a CERN fellow or graduate contract.

Educational Background:
A Master's degree in Mechanical Engineering, Materials Engineering, or a related field is required, with a preference for candidates who have a PhD. The educational background should include a strong foundation in mechanical and materials engineering principles, particularly as they relate to vacuum systems and materials characterization.

Experience:
Candidates should have relevant experience in working with metallic materials, particularly copper alloys, and ceramic materials for ultra-high vacuum applications. Experience with additive manufacturing processes, including plasma spray, cold gas dynamic spray, and 3D SLM printing, is essential. Familiarity with metals hot and cold work processing and welding technologies, including Laser and/or Friction Stir Welding, is advantageous. Practical experience in CNC machining and CAD design is also required.

Languages:
Proficiency in spoken and written English is mandatory, and knowledge of French is highly desirable. Candidates should demonstrate a commitment to learning the other language to enhance communication within the team and organization.

Additional Notes:
The position is fully onsite and involves working in radiation areas and 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 40 hours per week, and the target start date is February 1, 202

• The compensation includes a monthly net stipend of either 6372 or 7004 Swiss Francs, depending on the candidate's degree, along with 30 days of paid leave per year, comprehensive health insurance coverage, and a relocation package based on individual circumstances.
