HVAC Engineer (EN-CV-PJ-2023-109-GRAP)

  • Full-time

Job Description

The Engineering Department (EN) provides CERN with the engineering competences, infrastructure systems and technical coordination required for the design, installation, operation, maintenance and dismantling phases of the CERN accelerator complex and its experimental facilities. The mandate of the Cooling and Ventilation (CV) group is to carry out the engineering studies, operation and maintenance of the cooling systems, pumping stations, air conditioning installations and fluid distribution systems for the accelerator complex including their experimental areas and special cooling systems of the particle detectors. It also provides service to the CERN Control Centre and Computer Centre among other installations.

The Project Section (PJ) within the CV Group is in charge of the design, tendering and work phases of CV installations as well as feasibility studies for new plants: the size of these plants can range from small systems up to large-scale structures of several MW. The CV Group is looking for a HVAC Engineer in the Project Section to be in charge of the study and design of HVAC systems and cooling systems within the context of the HI-ECN3 project, whose aim is to full exploit the intensity reach of the SPS for Fixed Target physics and site a new High Intensity experimental facility in the existing ECN3 underground cavern of the North Area of CERN.

You will benefit from:

  • The opportunity to broaden your knowledge and experience into new areas like gas purification processes, fluid dynamics, nuclear ventilation, cooling and system installation and commissioning
  • Specific training and support for professional development to foster your skills and develop your talents

Your responsibilities

You will:

  • Design ventilation and cooling systems for a target complex
  • Design industrial cooling and ventilation systems for the experimental facility
  • Write up technical reports and notes
  • Draw up technical specifications and all relevant documents that will be used to adjudicate the work to external contractors
  • Be in charge of the test plan definition, execution and report

Your profile

Skills and/or knowledge


  • Communicating effectively, team working, managing self, flexibility.

About us

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 http://home.cern.
