Company Description

At CERN, the European Organisation 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.

Are you passionate about ensuring safety in highly complex environments? At CERN, you won’t just be managing safety - you’ll be shaping it at the very frontier of science. Step into a pivotal role supporting the world’s most advanced accelerator complex, including the Large Hadron Collider, and contribute to the protection and performance of the technologies pushing the boundaries of human knowledge.
