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 highly motivated and versatile mechanical engineer dreaming to take up a challenge at the frontiers of science? If that is you, seize this opportunity to join the central project team in the Experimental Physics Department on the Search for Hidden Particles experiment where you will have a key role in the design and realisation of the experimental infrastructure and critical components of the detector, as well as responsibility for control and integration of the SHiP subdetectors developed by the collaborating institutes.

The SHiP experiment is a recently approved experiment aiming at searching for signatures of feebly interacting particles that could for instance be at the origin of neutrino mass, dark matter and associated portal interactions. SHiP will be located on the CERN SPS accelerator at a new beam dump facility. The detector will be a sophisticated instrument composed of magnets and multiple detector components, stretching over 100m in an underground experimental hall. Its operation requires complex infrastructure in terms of large-scale support structures, electrical systems, cooling systems including cryogenics.


As a member of experiment central project team, you will collaborate closely with physicists, engineers, technicians, and designers, both from CERN and from collaborating institutes. You will have a central role in ensuring the successful design and implementation of the SHiP detector. In your role, you will coordinate the work of CERN personnel, collaborate closely with SHiP detector groups from collaborating institutes and provide guidance on integration of their components.

Specifically, you will:

  • Use CATIA V5 to prepare 3D models and 2D construction drawings;
  • Perform integration studies and specify requirements on the experimental infrastructure to the experimental facility team in the CERN accelerator and technical sector;
  • Take active role in detector assembly studies and later oversee detector production and construction;
  • Use ANSYS where needed for structural and mechanical dimensioning analysis, perform or lead thermal and fluid analysis for detector cooling;
  • Record and follow evolution of PLM (Product Lifecycle Management).


Master's degree or equivalent relevant experience in the field of design, engineering, physics or a related field.


The candidate should have: 

  • Demonstrated experience in working with 3D models and PLM;
  • Proven experience with managing CAD assemblies;
  • Working experience in multi-disciplinary teams;
  • Basic ANSYS structural and mechanical analysis.

Experience with thermal analysis and working in a multi-team environment would be additional assets.

Technical competencies:

  • Design and analysis of mechanical structures;
  • Production of 2D drawings and 3D models;
  • Integration of mechanical systems;
  • Assembly of mechanical structures and equipment;
  • Knowledge and application of numerical modelling in solid mechanics.

Behavioural competencies:

  • Working in teams: building and maintaining constructive and effective work relationships
  • Managing self: working well autonomously; taking on activities and tasks without prompting
  • Demonstrating flexibility: being willing to work on different projects simultaneously
  • Learning and sharing knowledge: sharing knowledge and expertise freely and willingly with others; coaching others to ensure knowledge transfer

Language skills:

Spoken and written English or French: ability to draw up technical texts in English, as well as ability to speak French in professional contexts.
