Job Details

Job Posting Organization:
CERN, the European Organization for Nuclear Research, was established in 1954 and is one of the world's largest and most respected centers for scientific research. With a mission to probe the fundamental structure of the universe, CERN employs thousands of scientists, engineers, and support staff from over 100 countries. The organization operates in multiple countries and is known for its groundbreaking work in particle physics, utilizing the world's largest and most complex scientific instruments to study fundamental particles and their interactions.

Job Overview:
The Numerical Modelling Engineer position at CERN's Infrastructure and Building Safety section is a unique opportunity for individuals with expertise in modelling physical processes. The role involves analyzing and developing complex thermodynamic and fluid dynamic systems as part of the Future Circular Collider (FCC) study. The engineer will engage in risk analysis studies, focusing on advanced multi-physics modelling and computational fluid dynamics, including evacuation modelling, fire and smoke propagation, and cryogenic gas release. This position offers a chance to work within a multidisciplinary team of engineers, physicists, and technicians, contributing to a wide range of research projects and pushing the boundaries of scientific knowledge.

Duties and Responsibilities:
As a Numerical Modelling Engineer, your responsibilities will include conducting risk analysis studies related to the FCC, developing and implementing numerical models for multi-physics applications, and performing computational fluid dynamics simulations. You will be expected to analyze fire and smoke propagation scenarios, model evacuation processes, and assess cryogenic gas release impacts. Collaboration with a diverse team will be essential, as you will share insights and findings with engineers and physicists. Additionally, you will be involved in benchmarking models, utilizing simulation software, and ensuring the accuracy and reliability of your simulations through continuous integration tests.

Required Qualifications:
Candidates must possess a strong background in modelling natural processes, particularly in dynamical systems and numerical integration, with a focus on thermodynamics and fluid dynamics. Experience in fire and smoke propagation is considered an asset. Proficiency in developing numerical models and solving differential equations for multi-physics purposes is required, along with knowledge of Python programming. The ability to work effectively in an international and multidisciplinary team is crucial, and fluency in English is mandatory. Experience with commercial and open-source simulation software such as Ansys, OpenFoam, FDS, and MATLAB is valuable, as is familiarity with model benchmarking and version control systems like git.

Educational Background:
The ideal candidate will have a professional background in Mechanical Engineering, Applied Physics, Computer Science, or a related field. A Master's degree accompanied by 2 to 6 years of post-graduation professional experience is required, or alternatively, a PhD with no more than 3 years of post-graduation experience. It is important that candidates have not previously held a CERN fellow or graduate contract.

Experience:
Candidates should have a minimum of 2 years of relevant professional experience post-graduation if holding a Master's degree, or up to 3 years if holding a PhD. Experience in numerical modelling, computational fluid dynamics, and risk analysis in a scientific or engineering context is essential for this role.

Languages:
Fluency in English is mandatory for this position. Knowledge of French is considered an asset but is not required.

Additional Notes:
The contract duration for this position is 24 months, with the possibility of extension up to a maximum of 36 months. The target start date is May 1, 202

• The role involves working in radiation areas and conducting interventions in underground installations. The position offers a competitive monthly stipend ranging from 6287 to 6911 Swiss Francs (net of tax), comprehensive health coverage for the employee and their family, and membership in the CERN Pension Fund. Additional benefits may include installation grants, family allowances, and travel expense reimbursements. Employees are entitled to 30 days of paid leave per year, along with opportunities for on-the-job training and formal language courses.
