Refrigeration Technician (EN-CV-INJ-2018-75-LD)

Geneva (Switzerland)

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


Are you a proactive, collaborative, multi-tasking and flexible technician? Are you attracted by working in a technical environment with complex and large-scale installations? This is a unique opportunity to support maintenance activities. CERN, take part!

You will join:

  • The Engineering Department (EN) that provides engineering competencies, infrastructure systems and technical coordination for the world's largest particle accelerator complex and its experimental facilities.
  • The Cooling and Ventilation Group (EN-CV), responsible for designing, constructing, maintaining, and operating cooling, ventilation and air conditioning systems and large scale fluid distribution systems for the whole Laboratory, particularly in the underground areas of the accelerators and experiments.
  • The Injector Section (INJ) in charge of the operation, maintenance and installation activities on the cooling and ventilation plants under the responsibility of the CV Group in the injectors complex.

 You will benefit from:

  • The opportunity to broaden your knowledge and experience in maintenance management, database and in cooling and ventilation industrial plants and work in a working environment where excellence is the key driving factor.
  • Specific training and support for professional development to foster your skills and develop your talents.


As a Refrigeration Technician in the CV Group, you will participate in installation projects as well as operation and maintenance activities of the existing CV plants. You will be expected to follow activities of varying degrees of complexity through to completion, reporting to a responsible engineer and interacting with various Groups and services. Your expertise in refrigeration systems and equipment will allow you to provide high-level support to the other members of the Group in different domains (design, troubleshooting, operation). Similarly, you will receive support from project engineers and various other technicians who are all experts in their own fields, where needed.

You will:

  • Follow up operation and maintenance activities on refrigerating equipment and optimize performance;
  • Provide support on refrigeration issues to other members of the Group;
  • Monitor and operate Cooling and Ventilation installations (cooling plants, air-conditioning systems, water pumping stations, units and networks), perform problem analysis and optimize performance with respect to operational needs;
  • Follow-up on and coordinate construction work on cooling and ventilation installations (water pumping, compressed air, chilled water production, and ventilation systems) to ensure they comply with safety rules, technical standards, and contractual documents and are within the established schedule and budget;
  • Propose priorities, plan and validate from the technical point of view repair or maintenance interventions to be performed on equipment under your responsibility;
  • Perform overall analysis of data and information (via CMMS software or by inspections on site) in order to define the maintenance and operation plan;
  • Monitor and follow up external contractors' activities to ensure compliance with contractual agreements and good practice on technical standards;
  • Propose adequate technical solutions to users' requests, take responsibility for all consequent actions to perform works;
  • Ensure conformity of the CMMS recordings with the work performed in situ;
  • Take part in stand by service; perform rounds on site.


Technical certificate or general secondary education in the field of refrigeration or a related field.

A nationally recognised accreditation as a Refrigerant Handler (F-Gas and Ozone depleting substances (ODS)) would be an advantage.


  • Demonstrated experience in air conditioning systems, industrial chillers, heat pumps, chilled water production plants and their processes;
  • Experience with cooling towers, demineralised water cooling circuits, ventilation, compressed air production, low voltage electrical systems, controls and process automation;
  • Initial experience in the use of CMMS software (INFOR EAM) and office (Microsoft Office);
  • Good knowledge of any of the following systems would be an asset: ventilation, compressed-air production or low-voltage electrical equipment.

Technical competencies:

  • Operation and maintenance of HVAC plants and networks: and ventilation installations including installation work on HVAC and compressed air systems;
  • Operation and maintenance of cooling water systems;
  • Maintenance management: use of maintenance management systems;
  • Operation and maintenance of electrical circuits and networks: controls and process automation;
  • HVAC process and regulation and cooling process and regulation;
  • Subcontracting, industrial support (contract supervision);
  • Use of Supervisory Control And Data Acquisition (SCADA) systems;
  • PLC programming knowledge would be an asset.

Behavioural competencies:

  • Demonstrating flexibility: readily accepting new tasks or work/projects; readily absorbing new techniques and working practices; proposing new or improved ways of working; demonstrating openness to new ideas and situations.
  • Managing self: working well autonomously; taking on activities and tasks without prompting; taking initiative beyond regular tasks and making things happen.
  • Achieving results: objectively assessing and monitoring own work; regularly reporting on progress and advising of any changes in schedule or priorities; having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.
  • Working in teams: building and maintaining constructive and effective work relationships; gaining trust and collaboration from others; seeking to help other team members when own work is done; supporting others.
  • Demonstrating accountability: working conscientiously and reliably; delivering on promises; maintaining confidentiality.

Language skills:

  • Spoken and written French: ability to understand and speak in professional contexts as well as the ability to prepare/draft accurate texts.
  • Knowledge of English or an undertaking to acquire it rapidly.
