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 a technician looking for a challenging professional experience to further your career?  If so, joining CERN’s TTE programme may very well give you that challenge.  This position as a Mechanical Technician is part of our prestigious TTE programme. 

The Sources, Targets and Interactions section (STI), in the Engineering Department, oversees the conceptual design, construction, operation and maintenance of all beam-intercepting devices across CERN’s accelerator complex, including particle-producing targets, beam absorbers/dumps, collimators, beam stoppers and slits. The Group is also responsible for the technical coordination of related facilities such as the Neutron-Time-of-Flight (n_TOF) and the Antiproton Target (ADT) areas.

Equipment under the responsibility of the Group need to safely absorb beams from extremely low energy (45 keV) up to extremely high energy (7 TeV), with kinetic energies up to 350 MJ and with average power reaching up to 400 kW.

You will join the team in charge of the conception, technical design, assembly, installation and maintenance of the beam intercepting devices (BIDs) managed by the TCD section. Depending on the particular project you will be joining, you will:

  • Participate in the conception, technical design and assembly activities for new and upgraded components, such as spallation targets, stoppers, slits, internal and external beam dumps and experimental devices;
  • Be involved in the routine maintenance and consolidation activities of equipment for the LHC accelerator complex, for the injector complex and/or for other facilities at CERN;
  • Provide mechanical and logistics support to the n_TOF and AD-target facilities in collaboration with the respective Technical Coordinators; tasks are associated to the daily operation, technical problem-solving, preparation of upgrades for the facility and for different experimental activities executed in the respective installation.

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 Technical Diploma ( in the field of mechanics or equivalent, and no more than 4 years’ relevant experience after finishing your diploma;
  • If you are currently studying, you are still eligible to apply, although you are expected to have obtained your qualification by the start of your appointment at CERN;
  • 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.

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;
  • A monthly stipend of 4565 Swiss Francs per month (net of tax);
  • Coverage by CERN’s comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund;
  • Depending on your individual circumstances: an installation grant, family, child and infant allowances as well as travel expenses to and from Geneva;
  • 2.5 days of paid leave per month.

Specific skills required for this job

  • Experience in using CAD systems such as CATIA
  • Experience in machining, assembling and testing of precision mechanics
  • Experience in reading mechanical design drawings and specifications in terms of tolerance (ISO tolerancing system).

This is how you can apply. Here are few tips to start you off:

  • Be as specific as possible in the application fields “Education” and “Experience”.
  • We recommend you prepare your answers in Word or Notepad in advance, as once you start completing the application on Smartrecruiters, you have a limited time to submit it.
  • If you apply to more than one job, you will need to upload the documents for each application you submit.

Required documentation:

You will need the following documents, clearly labelled (e.g. “CV”, “Motivation letter”, “Academic transcript”, etc.) and in PDF format to complete your application:

  • A CV;
  • A scanned copy of your latest relevant qualification;
  • One reference letter (from a professor or previous employer) giving an overview of your academic and/or professional achievements. This should be as broad as possible.

Make sure you have all the documents needed to hand as you start your application, as once it is submitted, you will not be able to upload any documents or edit your application further. 

You may upload the reference letter yourself, whilst submitting your application, or through your referee via the link you will receive shortly after submitting your application.

All applications should normally reach us no later than 29.09.2020.
