Safety Engineer (HSE-OHS-IB-2025-85-GRAE)

Job Description

Your responsibilities

Are you knowledgeable in safety systems and risk assessment? Do you want to analyse and develop a safety concept in a unique and challenging research infrastructure? Then your Origin starts here. Deepen your knowledge and expertise faster than anywhere else on earth. Take Part!

CERN's Infrastructure and Building Safety section of the Occupational Health and Safety and Environmental Protection ( HSE ) Unit is looking for a Safety Engineer to join the team working on the Einstein Telescope project. You will be involved in risk analysis studies, including advanced modelling and development of safety concepts for a new underground research infrastructure. You will also participate in a wide range of other research projects, working within a multidisciplinary and diverse team of engineers, physicists and technicians.

About Einstein Telescope:
The Einstein Telescope (ET) is a proposed underground facility for a third-generation gravitational-wave observatory. Building on the success of Advanced Virgo and Advanced LIGO, which detected merging black holes and neutron stars, ET will have a much higher sensitivity. This will be achieved with 10km interferometer arms (up from Virgo's 3km), a depth of 150-300 meters underground, and new technologies like cryogenic cooling of optics around 15K, quantum techniques to reduce light fluctuations, and advanced noise-reduction systems. ET will enable exploration of the Universe's gravitational waves back to the cosmological dark ages, offering insights into fundamental physics and cosmology.

Your profile

Skills

Required:

• Background in risk assessment methodologies such as qualitative, semi-quantitative, quantitative or probabilistic (e.g. HAZOP, FMEA, ETA, FTA, Monte Carlo);
• Knowledge in industrial safety and emergency safety systems;
• Knowledge in the regulatory framework for occupational health and safety, namely in Europe;
• Knowledge in mathematical modelling, particularly by running models in commercial or tailored-made software tools;
• Experience in drafting and editing safety-related reports, assessments and specifications to present to decision makers and/or to the authorities;
• Capability to work in an international and multidisciplinary team.

Valuable:

• Experience in Python programming language;
• Experience in computational fluid dynamics or any other advanced multi-physics models;
• National or International accreditation in the field;
• Spoken and written English, with a commitment to learn French.

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.
