Particle Accelerator Operator (BE-OP-SPS-2022-34-LD)

  • Geneva, Switzerland
  • Contract

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


Are you passionate about science, physics, engineering, computing or a related domain?

We invite you to take your career to an exciting new level by joining the team of operators who run the CERN accelerator complex in the CERN Control Centre (CCC). Join Team CCC! CERN, take part!

The Operations Group is responsible for the exploitation of the entire CERN accelerator complex and its technical infrastructure, including the Large Hadron Collider (LHC), running a rich proton, antiproton and heavy ion experimental programme. You will be at the heart of the preparation of particle beams for the different physics programs at CERN.
