Job Description

Your responsibilities

Are you knowledgeable in fire safety? Do you want analyse and develop fire protection measures in a unique and challenging infrastructure? Then this is your Quest. 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 Fire Safety Engineer to join the Fire Safety Engineering Team. You will be involved in fire risk analysis studies (including advanced fire dynamics) and fire safety concepts development for the Einstein Telescope. You will be in charge of the fire safety concept and contribute to the global safety concept. You will work in a multi-disciplinary and diverse team of engineers, physicists and fire officers.

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 fire risk assessment, fire prevention, as well as fire scenarios and human behaviour in fire;
• Knowledge in industrial safety and emergency safety systems as well as fire resistance and reaction of materials;
• Knowledge on fire dynamics, fire modelling (CFD, as per example FDS). Performance-base design experience will be an asset;
• Capability to work in an international and multidisciplinary team;
• Original thinker and problem solver.

Valuable:

• Experience in fire safety engineering methods and quantitative fire risk analysis;
• Knowledge in prescriptive fire safety and regulatory frameworks (i. e. EU, CH, FR, etc);
• Knowledge of passive and active fire protection solutions (compartmentalization, fire detection, fixed and mobile extinguishing systems, etc);
• Pro-activity and capacity to work autonomously and effectively on parallel tasks;
• Spoken and written English, with a commitment to learn French.

Eligibility criteria:

• You are a national of a CERN Member or Associate Member State.
• You have a professional background in Fire Safety / Safety Engineering (or a related field) and have either:
  • a Master's degree with 2 to 6 years of post-graduation professional experience;
  • or a PhD with no more than 3 years of post-graduation professional experience.
• You have never had a CERN fellow or graduate contract before.

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.
