Job Description

Your responsibilities

Are you a mechanical engineer looking for a challenging professional experience to further your career? If so, joining CERN's graduate program may very well give you that challenge.

The mandate of the MME group is to provide to the CERN community specific engineering solutions combining mechanical design, fabrication and material sciences. Historically the group maintains and develops the know-how on the mechanical construction of beam accelerator components and physics detectors. MME involves a large spectrum of highly specialized activities, including on-site facilities and sub-contracting: CAD design, advanced calculations, high precision CNC machining, sheet metal forming, welding and vacuum brazing, dynamic and static measurements, micrometric 3D metrology, metallurgical analysis, destructive and non-destructive material testing.

The Design Office is in charge of mechanical design of components required for CERN's accelerator and detectors, comprising many high tech. equipment such as superconducting magnets and cavities, vacuum systems and instrumentation. This involves studies and developments of new products from conceptual ideas to fully detailed engineered solutions using parametric 3D modelling and 2D drafting, structural, thermal, fluid-dynamic, shock and vibration analyses. These activities are carried out relying on a large range of CAD and CAE tools, mainly Dassault Systems, CATIA v5, SmarTeam, Ansys Multiphysics and Workbench.


  • You will use the CATIA V5 to produce 3D models and 2D construction drawings of components for accelerators and detectors.
  • Carry out mechanical dimensioning of components using analytical or numerical methods.
  • Design components and propose solutions for different mechanical problems.
  • Prepare 3D models and 2D drawings. Use the ISO GPS norms for dimensioning and tolerancing.
  • Procure components and follow the construction of the elements you have designed.

Your profile

Skills and/or knowledge

  • Design in Mechanical engineering field CAD 3D and 2D ISO GPS norms for dimensioning and tolerancing Team work
  • Fluent in English, the ability to work in French would be an advantage.

Eligibility criteria:

  • You are a national of a CERN Member or Associate Member State.
  • By the application deadline, you have a maximum of two years of professional experience since graduation in Mechanical Engineering (or a related field) and your highest educational qualification is either a Bachelor's or Master's degree.
  • You have never had a CERN fellow or graduate contract before.
  • Applicants without University degree are not eligible.
  • Applicants with a PhD are not eligible.

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


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.
