Job Description
Your responsibilities
The Mechanical and Materials Engineering (EN-MME) group within the Engineering Department (EN) is looking for a Mechanical Engineer to perform engineering studies calculations and support to the fabrication for the High Luminosity (HL)-LHC Collimators.
The collimators are critical elements of the LHC machine providing particle beam cleaning and protecting the superconducting magnets. A total of 36 new collimators and 15 masks are being produced for installation in the LHC tunnel during the Long Shutdown 3. The HL-LHC WP5 is the work package (WP) dedicated to the design production testing and installation of the collimators.
You will join the WP5 EN-MME engineering team with the main task of providing engineering support to the development and fabrication of the collimation systems as well as to the study of their configuration in the LHC under beam losses. Examples of the calculations required include structural thermal multiphysics (e.g. fluid-dynamic simulations coupled with thermo-structural FEM) fluid-dynamics vibration simulations as well as analytical computations.
You will participate to the regular project meetings presenting the results of your studies and actively contributing to the advancement of the project. You will work in strong collaboration with the groups involved in the WP5. You will also be required to prepare reports and technical notes to document the work done.
Your profile
Skills
Calculations & Simulations:
- Proven experience with finite element analysis software for thermal and structural simulations (e.g. ANSYS COMSOL);
- Ability to analyse and interpret simulation data to guide design decisions and understand operational failure mechanisms;
- Understanding of the behaviour and design principles of ductile and brittle materials at room and low temperatures;
- Initial experience with 3D CAD software (e.g. CATIA);
- Familiarity with International Standards dealing with the design and safety of structural and pressure equipment (e.g. Eurocode EN-13445) would be an asset.
Experimental Activities:
- Willingness and ability to engage in experimental activities including hardware assembly testing and procurement support;
- Ability to coordinate and manage weekly meetings and follow up of activities.
Soft Skills:
- Attitude to teamwork in a multidisciplinary environment;
- Excellent communication and documentation skills;
Language Skills:
- 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 worlds 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 .
Diversity has been an integral part of CERNs mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
