Technical Engineer for Water Treatment Systems (EN-CV-CES-2026-124-LD)

ph3Company Description /h3 pAt 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. /p h3Job Description /h3 pThe Engineering Department (EN) pushes forward the limits of technology so that physicists can carry out their research. Within the EN department, the Cooling and Ventilation (EN‑CV) group is responsible for the design, construction, operation and maintenance of the cooling and ventilation plants for large energy physics accelerators, experiments and technical facilities. The EN‑CV group pursues sustainable cooling and ventilation systems enhancing energy savings and recovery. /p pYou will join the Methods, Store and Electrical Section (CES), which oversees the operation and maintenance of water treatment systems, as well as the development of maintenance procedures, implementation of computerised maintenance management (CMMS), documentation management, spare parts store management and electrical works. /p pIn this role, you will contribute to the analysis, optimisation and development of water treatment systems used for cooling and ventilation installations.
