Opportunities in Geneva, Switzerland

Full job description

Come and join the cryogenics maintenance team within the Technology Department (TE), specifically within the Maintenance Methods and Logistics section. We're offering a unique opportunity to work and contribute to the preparation of the next maintenance technical shutdown and integration of new major assets in the maintenance systems.

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.

Typical cryogenic systems comprise compressors, heat exchangers, valves, instrumentation, vacuum pumps, controls and various test benches for cables, magnets and RF cavities. Process gas purity is essential.

The experience you will gain as a member of the cryogenics maintenance team could not be acquired anywhere else, teaching you to work autonomously and address maintenance solution to large and complex systems. Be part of a team overseeing the organisation of Long Shutdown 3 for the cryogenics infrastructure and provide your input.

Your responsibilities:

• Collecting and consolidating maintenance data within the Computerised Maintenance Management System (CMMS) - Supporting the preparation and coordination of maintenance activities on-site.
• Rolling out new maintenance methodologies in collaboration with field technicians.
• Enhancing work instructions, checklists, and quality assurance procedures used by contractors.
• Contributing to the implementation of maintenance policies and best practices for new cryogenic assets as part of the HL-LHC (High-Luminosity Large Hadron Collider) project.

Take this opportunity to work on one of the most advanced cryogenic systems in the world and make your mark on a project of global scientific importance.
