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

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization.

Job Description

Are you an enthusiastic technician looking for a challenging professional experience to further your career?  If so, joining CERN’s TTE programme may very well give you that challenge.  

Come and join the team of cryogenics operation of the SM18 test facility in the Technology Department. The group is responsible of the design, construction, operation & maintenance of cryogenic systems for accelerators and detectors. It is a unique opportunity to work and contribute to test the new generation of magnets and radiofrequency cavities for High Luminosity LHC project (upgraded LHC).

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. The SM18 is one of the most important infrastructure to test sets of superconducting components able to operate in the CERN accelerators.

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.

From start-up and routine operation to maintenance support and emergency operation interventions, key point stands in maintaining the highest availability for the cryogenics equipment and reaches the SM18 target: allowing efficient tests for all the requested magnets and radiofrequency cavities within the allocated time while respecting safety, quality, priorities and procedures.

The experience you will gain as a member of the SM18 cryogenics operation team could not be acquired anywhere else, teaching you to work autonomously and to respond to all manner of situations around complex processes.


As member of the Cryogenics team, you will:

  • Be part of a team which runs the cryogenics testing facilities supporting the tests of cables, magnets and RF cavities developed and qualified by CERN at the SM18 testing facility for future upgrade of the LHC machine in the Hi Lumi project;
  • Participate to the ramp-up of a brand new helium liquefier commissioned and started in 2020;
  • Contribute to the continuous optimization of the cryogenics process and communicate about possible operation upgrades;
  • Integrate a multinational team with a range of skills and expertise;
  • Get the chance to broaden your knowledge into new areas;
  • Receive specific training and support for your professional development.

After a period of training, you will take on responsibility, on the ground and remotely, for operating the cryogenic system e.g.: trouble-shooting, emergency operation interventions, maintenance support, follow-up of contractor operation team depending on requirements and situations, updating the operating procedures, in particular with respect to the safety rules; and managing technical documentation.


In order to qualify for a place on the programme you will need to meet the following requirements:

  • You are a national of a CERN Member State or Associate Member State (;
  • You have a Technical Diploma or equivalent in industrial instrumentation, physical measurements, process engineering, and no more than 4 years' relevant experience after finishing your diploma;
  • If you are currently studying, you are still eligible to apply, although you are expected to have obtained your qualification by the start of your appointment at CERN;
  • If you hold a BSc or MSc, you are not eligible. However you may be eligible for the Fellowship Programme.
  • You should have at least a working knowledge of English or French.

Specific skills required for this job:

First experience in the monitoring of industrial processes and/or experience in the field of commissioning and operation of complex electromechanical plant (e.g. petrochemicals, large-scale facilities for renewable energies or equivalent).

Specific experience with complex industrial processes, automatism or cryogenics or vacuum technologies would be a major asset, as would be basic knowledge of thermodynamics.

Technical competencies:

  • Practical knowledge on office software packages;
  • Cooling process and regulation: understanding of basic process cycles and regulation (P.I.D);
  • Practical knowledge in mechanics (basics);
  • Use data acquisition and treatment software.

Behavioural competencies:

  • Solving Problems: identifying, defining and assessing problems, taking action to address them;
  • Managing Self: working well autonomously, taking on activities and tasks without prompting;
  • Communicating Effectively: ensuring that information, procedures and decisions are appropriately documented;
  • Learning and Sharing Knowledge: taking steps to expand knowledge in other areas of expertise beyond own field;
  • Working in Teams: building and maintaining constructive and effective work relationships.

Additional Information

CERN would very much like to benefit from your expertise, commitment and passion.  In return, CERN will provide you with:

  • An employment contract of one year, renewable for a second year; 
  • On-the-job and formal training (in the design and implementation of electrical systems) at CERN as well as in-house language courses for English and/or French;
  • A monthly stipend of 4585 Swiss Francs per month (net of tax);
  • Coverage by CERN’s comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund;
  • Depending on your individual circumstances: an installation grant, family, child and infant allowances as well as travel expenses to and from Geneva;
  • 2,5 days of paid leave per month.
