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

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.

- 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.  

- 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. Eligibility criteria: - You are a national of a CERN Member or Associate Member State . - 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.
