Mechanical Designer for Radio Frequency Systems


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

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization.


Job Description

Are you an enthusiastic Mechanical Designer looking for a challenging professional experience to further your career?  If so, joining CERN’s TTE programme may very well give you that challenge.  


As a Mechanical Designer you will join the SY-RF-AC section, which is in charge of RF power devices over all CERN’s accelerator complex. 

You will reinforce the team and be involve at all stages of the design, construction, and tests of RF power devices. A senior technician will mentor you all along the projects.

After an initial training period, you will:

  • Produce out-of-the box designs using office-computing applications and liaise with CERN’s Main Workshop and with other relevant services at CERN and with external companies;
  • Participate in the operation and maintenance of existing systems;
  • Contribute to the development and prototyping of improved systems and their components for consolidation and upgrade of accelerators;
  • Participate in installation and commissioning of these systems;
  • Produce and manage the associated technical documentation and test reports.

Skills required for this project:

  •  Conception of mechanical objects
  •  Use of CAD (Catia, Ansys)
  • Machining
  • Metrology
  • Installation and tests of equipment 



In order to qualify for a place on the programme you will need to meet the following requirements:

  • You are a national of a CERN Member State or Associate Member State (;
  • You have a Mechanical Technical Diploma or equivalent in mechanics (, and no more than 4 years' relevant experience after finishing your diploma;

  • If you hold a BSc or MSc, you are not eligible. However you may be eligible for the Fellowship Programme.
  • You should have at least a working knowledge of English or French.

Training Value

This is a fantastic and unique chance to take part in the future of CERN! You will have the opportunity to become a skilled technician in various fields of expertise. This includes: CAD, conventional and modern machining, 3D fast prototyping, EBW, Laser welding, subcontracting follow-up, assembly, clean room tooling, vacuum technology, RF measurements etc.



Additional Information

CERN would very much like to benefit from your expertise, commitment and passion.  In return, CERN will provide you with:

  • An employment contract of one year, renewable for a second year; 
  • On-the-job and formal training at CERN as well as in-house language courses for English and/or French;
