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 a Safety Engineer or equivalent with experience and knowledge in Health, Safety and Environment matters? Do you have strong skills in improving safety at the workplace in an efficient and collaborative approach? Would you like to contribute to upgrading, developing, maintaining and operating one of the largest particle-physics experiments in the world? Then take part!

You will join:

  • Experimental Physics Department (EP), which carries out basic research in the field of experimental physics. It aims to provide 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 and engineers.
  • The ATLAS Detector Operation Group (ADO) and in particular the technical coordination team, which has the responsibility to ensure the operation and maintenance of the ATLAS detector and its infrastructure. In particular, the safety of the experiment is one of the team’s core responsibilities.


As Safety Engineer in the ATLAS technical coordination team, you will:

  • Assume the role of the Deputy Large Experiment Group Leader in Matter of Safety (DLEXGLIMOS) and Radiation Safety Officer (RSO).
  • Be co-responsible for defining and updating the safety procedures to be applied at the experiment.
  • Perform risk assessments.
  • Coordinate the operation and maintenance of the ATLAS safety systems.
  • Participate to the day-to-day management of safety aspects at the experiment.

  • Experience in health, safety and environment regulations including radiation protection.

Technical competencies:

  • Occupational safety and risk management.
  • Maintenance and operation of safety systems.
  • Safety conformity assessment.
  • Management of emergency calls.
  • Accident analysis.
  • Knowledge of regulatory framework and best practice in radiation protection.

Behavioural competencies:

  • Working in teams: building and maintaining constructive and effective work relationships; gaining trust and collaboration from others.
  • Achieving results: defining clear objectives, milestones and deliverables before initiating work/ project ; objectively assessing and monitoring own work; regularly reporting on progress and advising of any changes in schedule or priorities ; having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.
  • Communicating effectively: successfully changing other people's opinions by persuasive arguments ; checking to ensure that the message has been well understood ; ensuring that information, procedures and decisions are appropriately documented.
  • Solving problems: recognizing what is essential; discriminating between important and peripheral information and being able to see the whole picture ; seeking and integrating other points of view when tackling an issue ; consulting experts in the field and undertaking benchmarking.
  • Demonstrating flexibility: demonstrating willingness to alter views when presented with new information ; adapting quickly and resourcefully to shifting priorities and requirements ; readily absorbing new techniques and working practices; proposing new or improved ways of working.

Language skills:

Spoken and written English, with the ability to draw-up technical specifications and scientific reports and to make oral presentations. The ability to understand and speak French in professional contexts would be an advantage.
