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 forward the limits of technology to provide innovative research tools to the physics and engineering worldwide community. Within the cooling and ventilation (CV) group of the EN department, you will join the Injectors Section (INJ), which is in charge of the maintenance, operation, performance of minor works for cooling & ventilation installations in the injectors complex and for the water treatment plants in all complexes.

Are you a qualified and proactive technician specialized 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 INJ Section, you will take part in the operation, maintenance and modification works of cooling and ventilation plants, in particular of the ones related to the water treatment installations.

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 on the water treatment installations.
  • Perform operation and maintenance activities to ensure an appropriate run of the water treatment plants.
  • Regularly liaise with users for all matters related to the water treatment.
  • Propose and define the most appropriate solution for the water treatment in case of new system, 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 plants;
  • Write up technical reports and notes.
  • Ensuring that the technical documentation is kept up to date and compliant with the quality standards.

  • Experience in the use of CMMS tools.
  • Experience in low voltage electrical system.
  • Initial experience in compressed air plants.

Technical competencies

  • Operation and maintenance of cooling water systems: including design and construction for water treatment plants as well as for compressed air stations, HVAC plants 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.

Behavioural competencies

  • Achieving results: delivering high quality work on time and fulfilling expectations Having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.
