Mechanical Technician (TE-CRG-ME-2018-136-LD)

  • Geneva, Switzerland
  • Contract

Company Description

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on

Job Description


It's big, it's loud, it's cold, and it's a challenging and exciting place to work! Come and join the mechanical team supporting, consolidating, developing and maintaining CERN cryogenic facilities, a unique opportunity to work on large and complex cryogenic equipments and to participate to the design, construction, installation and commissioning of cryogenics systems for accelerators, detectors and test facilities. CERN, Take Part!


As mechanical technician in the Technology Department (TE), Cryogenics Group (CRG), Mechanical and Engineering support section (ME), you will participate in the development and consolidation of cryogenic equipment for CERN accelerators, detectors and test areas. The activity ranges from the design to the commissioning phase of equipment, including the definition and participation to maintenance programs. For more information:
