  • The Project Section (PJ) within the CV Group, 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.

You will benefit from:

  • The opportunity to broaden your knowledge and experience into new areas and discover a domain where excellence is the key driving factor.
  • Specific training and support for professional development to foster your skills and develop your talents.


As a Cooling and Ventilation Engineer, you will:

  • Take responsibility for complex project management, including supervision of staff assigned to the project.
  • Carry out feasibility studies or detailed design studies for ventilation or cooling and compressed air systems including sizing and cost estimates for the proposed solutions.
  • Follow up project progress and regularly report on issues, schedule and costs, throughout all phases from installation to commissioning and the formal reception of the works.
  • Draw up technical specifications and all the relevant documents needed for the adjudication of the works for external contractors.
  • After having managed the contract tendering and participated in the adjudication process, ensure technical contract management and supervision of contractors in charge of the works.
  • Write up technical reports and notes.
  • Participate in the commissioning of the system.
  • Support the other Group members in process improvement of existing plants and their operation.
