As Health, Safety and Environment Officer, you will join the CERN Experimental Physics (EP) Department and ATLAS, one of the four large experiments exploiting the CERN Large Hadron Collider. The EP Department carries out basic research in the field of experimental and theoretical particle physics. It aims at providing a stimulating scientific atmosphere and remains an important reference centre for the European physics community. It contributes to the education and training of young scientists.

You will be part of the ATLAS technical coordination team, under the supervision of the Group Leader in Matters of Safety (LEXGLIMOS). The technical coordination team has the responsibility to ensure the operation and maintenance of the ATLAS detector and its infrastructure. The safety of the experiment is one of the team's core responsibilities.

• Update safety procedures and documentation.
• Analyse safety incidents and follow-up on action plans.
• Provide safety training for CERN collaborators.
• Ensure maintenance of safety equipment.
• Organise evacuation exercises and follow safety training courses (e.g., First-aid, Emergency Guide, Scaffolding controller).

During Long Shutdown 3, starting in July 2026, when ATLAS will host many upgrades and activities, you will:

• Lead safety tours: perform regular tours underground and at surface buildings, communicate with on-site workers, define and follow-up on actions.
• Attend work preparation and safety visits before the start of work.
• Perform shifts in the ATLAS control room.
• Accompany VIP and press visits underground.

About us

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.

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
