Mechanical Technician (TE-CRG-ME-2025-84-GRAE)

Job Description

Your responsibilities

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 equipment and to contribute to the design, construction, installation and commissioning of cryogenic systems for accelerators, detectors and test facilities.

As a Mechanical Technician, you will support the operation and maintenance of CERN's cryogenic systems, playing a hands-on role in some of the world's most advanced scientific infrastructure.

Your main responsibilities will include:

• Contributing to the design, procurement, manufacturing, assembly, installation and commissioning of cryogenic equipment used in CERN's accelerator, detector, and test facilities.
• Supporting field activities across CERN sites as part of a team responsible for the installation, assembly, and maintenance of cryogenic systems and mechanical infrastructure.
• Participating in the management of technical documentation, from detailed equipment specifications to Quality Assurance Plans.

Your profile

Skills:

• Basic knowledge in:
  • Design, installation and testing of industrial systems or components;
  • Cryogenics and/or vacuum technology (theoretical exposure is sufficient);
  • Fluid dynamics and heat transfer phenomena;
  • Application of manufacturing methods and assembly of mechanical equipment and structures.
• It would be an asset to have experience or familiarity with:
  • Production monitoring in an industrial or technical context;
  • Mechanical welding techniques, particularly for stainless-steel assemblies;
  • Commissioning and maintenance of mechanical equipment and systems;
  • Writing procedures and updating technical data in a maintenance management system.

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

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State .
• By the application deadline, you have a maximum of two years of professional experience since graduation in Technical diploma in mechanics (or a related field) and your highest educational qualification is a general secondary education diploma.
• You have never had a CERN fellow or graduate contract before.

About us

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 http://home.cern.

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
