Job description

Mechanical Engineer for Vacuum (TE-VSC-DLM-2026-173-GRAP)

• Full-time


• Compensation: CHF 6,372 - CHF 7,004 - monthly

As a Mechanical Engineer for Vacuum you will join the team working on the vacuum systems for a future accelerator at CERN (FCC-ee) and contribute to the selection, characterisation and validation of materials and processes for ultra-high vacuum components. In this role, you will be involved in defining samples and prototypes, their production and procurement, as well as their testing and validation.

Your responsibilities

• Actively participate in the development of the FCC-ee vacuum systems, particularly in materials and process selection, characterisation and validation, as well as prototyping.


• Contribute to the internalisation and in-house development of key manufacturing technologies for large component production.


• Collaborate with a dynamic team dedicated to the FCC-ee study.


• Communicate regularly with CERN-wide services and external companies or institutes.

Your profile

• Experience with metallic, in particular copper alloys, and ceramic materials for UHV applications.


• Experience with metallic and ceramic additive manufacturing processes, including plasma spray, cold gas dynamic spray and 3D SLM printing.


• Experience with metals hot and cold work processing and welding technologies. Experience with Laser and/or Friction Stir Welding is an advantage.


• Fabrication of mechanical parts with CNC machine, in particular with CAM software.


• Production of samples for materials characterisation including microscopic observations.


• Prior knowledge or use of WorkNC is an advantage.


• Design of mechanical parts with CAD program. Use of CATIA is an advantage.


• Spoken and written English or French, with a commitment to learn the other language.


• You have a professional background in Mechanical/Materials & Process Engineering(or a related field) and 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.
  
  
  
  


• You have never had a CERN fellow or graduate contract before.

Contract duration: 24 months, with a possible extension up to 36 months maximum.

Working hours: 40 hours per week

Job flexibility: Fully Onsite

This position involves:

• Work in Radiation Areas.


• Interventions in underground installations.


• A valid driving licence.
