Job Details

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 so that physicists can carry out their research. Within the cooling and ventilation (CV) group of the EN department, you will join the PJ Section (Projects), which is in charge of coordination and management of cooling and ventilation projects for installation of new systems, upgrade of existing systems and consolidation of old systems both for CERN accelerators and experiments.

Are you a qualified mechanical engineer, specialised in industrial cooling and ventilation installations? Contribute your skill and experience to the design and construction of highly complex large cooling and ventilation plants in a unique environment hosting some of the world’s most complex technical installations. Join CERN’s Cooling and Ventilation Project team. Take part!


As a Mechanical Engineer, you will take a leading role in the design and construction of HVAC and cooling systems within the context of PJ Section projects.

You will:

  • Compile and analyse user requirements from main stakeholders;
  • Perform feasibility studies or detailed designs of HVAC and/or cooling systems including sizing and cost estimates for the proposed solutions;
  • Produce technical reports and notes;
  • Draw up technical specifications and all relevant documents that will be used to adjudicate the work to external contractors;
  • Manage the contract tendering and adjudication process;
  • Follow up and regularly report on project's progress issues;
  • Ensure technical coordination and supervision of contractors and keep under control cost and schedule up to the commissioning and formal acceptance of the systems;
  • Provide engineering support to the colleagues in charge of the operation in the troubleshooting and process improvement of existing plants.
  • Actively contribute to the development and improvement of the internal procedures, internal technical prescriptions, and standardisation of the technical solutions.


Master's degree or equivalent relevant experience in the field of Mechanical Engineering or a related field.


  • Demonstrated experience in the design, construction and test of large-size ventilation installations and their related hydraulic components and/or large size industrial cooling including experience in selecting related equipment and instrumentation;
  • Proven experience in contract management;
  • Demonstrated experience in project management.

The following competencies would be an asset:

  • Experience in design, construction and test of ventilation systems for chemical plants and/or nuclear installations;
  • Experience of quality management;
  • Experience of low voltage network and switchboards.

Technical competencies:

  • Design and construction of cooling water systems: (raw, demineralised and chilled water) including test of plants and their associated equipment);
  • Design and construction of HVAC plants and networks: including test of plant and associated equipment;
  • Design, construction, operation and maintenance of compressed air systems
  • Water cooling process design and analysis: as well as HVAC process;
  • Project management
  • Contract management

Behavioural competencies:

  • Communicating Effectively: ensuring that information, procedures and decisions are appropriately documented
  • Working in Teams: building and maintaining constructive and effective work relationships
  • Managing Self: working well autonomously; taking on activities and tasks without prompting
