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


The Engineering Department (EN) pushes back the limits of technology so that physicists can carry out their research. Within the cooling and ventilation (CV) group of the EN department, you will join the LHC Section (LHC), which is in charge of the maintenance, operation, performance of minor works for cooling & ventilation installations in the LHC complex, in particular for the cooling of detectors.

Are you a qualified and proactive technician specialised in cooling and ventilation systems, willing to contribute to a unique working environment at the heart of one of the world's most complex and exciting scientific experiments? Then, this opportunity is for you – join the largest particle physics research laboratory in the world. CERN, take part!


As Technician in the LHC Section, you will take part in the operation, maintenance and modification works of cooling and ventilation systems, in particular of the ones related to the cooling of detectors.

You will:

  • Plan (by using the CMMS system), coordinate, supervise, check and perform preventive and corrective maintenance activities on cooling and ventilation plant and, in particular the detector cooling systems for the LHC Experiments.
  • Perform operation activities to ensure appropriate running of the cooling systems.
  • Ensure regular liaison with Experiments’ users for all matters related to the cooling systems.
  • Propose and define the most appropriate solution to meet user needs in case of modification or renovation works.
  • Technically coordinate contractors’ maintenance and installation work in compliance with contractual clauses and technical standards;
  • Contribute to projects from the design phase until test and commissioning of the systems.
  • Write technical reports and notes;
  • Ensuring that the technical documentation is kept up-to-date and compliant with the quality standards.
  • Ensure the respect of safety rules for all interventions.
  • Participate to the stand-by service


Higher technical diploma in the field of mechanics or electro-mechanics or a related field.


  • Demonstrated experience in maintenance, operation and installation work on cooling and ventilation systems.
  • Experience in the technical coordination of external contractors.
  • Experience in the use of CMMS tools.
  • Experience in low voltage electrical system
  • Initial experience in compressed air systems

Technical competencies:

  • Operation and maintenance of cooling water systems: including construction work as well as compressed air production stations, water distribution systems and HVAC systems and networks;
  • Contract management: in particular technical supervision of contracts;
  • Organisation, planning and control: coordination of activities involving different technical fields (electricity, civil engineering, heavy handling etc.).
  • Operation and maintenance of electromechanical equipment and systems: lV network and switchboards.
  • Construction, operation and maintenance of detector cooling systems.


Behavioural competencies:

  • Achieving Results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind
  • Managing Self: working well autonomously; taking on activities and tasks without prompting
  • Working in Teams: working well in groups and readily fitting into a team; participating fully and taking an active role in team activities
  • Demonstrating Flexibility: readily accepting new tasks or work/projects Adapting quickly and resourcefully to shifting priorities and requirements
  • Solving Problems: identifying, defining and assessing problems, taking action to address them Adopting a pragmatic approach; understanding the value of adopting generic rather than
