Company Description
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

Job Description
Do you have several years of experience in mechanical work coordination? If you think that worksite coordination in particles accelerators environment is a challenge and a real opportunity, you should definitely seize this opportunity! CERN, take part!
