Water treatment technician for industrial cooling systems (EN-CV-WMC-2025-5-LD)

Water treatment technician for industrial cooling systems (EN-CV-WMC-2025-5-LD)

• Contract

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.
