Mechanical Engineer (TE-CRG-ME-2025-148-LD)

It's big, it's loud, it's cold, and it's one of the most challenging and exciting environments you can work in! Join the mechanical engineeering team of the Cryogenic Group for a unique opportunity to work on machines that constitute nearly half of the world's large helium liquefiers. CERN, Take Part!

At CERN, helium needs to flow like water from a tap. CERN is the world's largest particle physics laboratory and its flagship accelerator, the Large Hadron Collider, depends on having an unrivalled set of cryogenic systems on hand to guarantee reliable operation. To sustain and extend its discovery potential, the LHC in undertaking a major upgrade, known as High Luminosity LHC (HL-LHC). New large-scale cryogenic infrastructure interfacing with existing machines and cryogenic distribution lines will be required.

The Cryogenics Group (CRG) in the Technology Department (TE) is responsible for the design, construction, commissioning, operation, and maintenance of cryogenic systems for accelerators and detectors, as well as for cryogenic test facilities. The group also supports low-temperature developments and tests at the Central Cryogenic Laboratory, which provides expertise in cryogenic design and instrumentation.

Functions:

As Mechanical Engineer in the Technology Department (TE), Cryogenics Group (CRG), Mechanical and Engineering support section (ME), and as a member of the Project Team for the Cryogenic Distribution System of the HL-LHC project your functions will include:

• Designing cryogenic equipment and overseeing its construction in close collaboration with external suppliers and internal partners. Managing the associated technical documentation;
• Organising the installation of complex cryogenic equipment. Preparing and managing the corresponding quality controls and documentation;
• Contributing to project management activities and quality assurance;
• Managing components procurement and production follow-up;
• Collaborating with people and services inside and outside the Organization.
