Technician for Water Treatment Systems (EN-CV-WMC-2025-211-LD)

Introduction

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 Water Management and Consolidation Section, which is in charge of the operation and maintenance of the water treatment systems of CERN’s accelerator complex and experimental areas. The activity includes the work site supervision for installation work and commissioning of new systems, upgrade of existing systems and consolidation of old systems.  

Are you a qualified technician, specialised in water treatment systems such as reverse osmosis, ultrafiltration or softener? Contribute your skill and experience to the operation and maintenance of complex cooling plants in a unique environment hosting some of the world’s most complex technical installations. Join CERN’s Cooling and Ventilation operation team. Take part!
