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

CERN's  Large Magnet Factory (TE-MSC-LMF) section is looking for a CNC Machine Programmer to work closely in the design office and the manufacturing workshop. As a CNC Machine Programmer, you will mainly support and optimize the manufacturing on the CNC machines by preparing optimized programs for these machines. In addition you will also carry out routine machine maintenance work and support monitoring and controlling maintenance costs e.g. research price of components with external vendors and ordering machinery parts.

CERN's LMF section, which sits within the Technology Department, is responsible for the manufacturing, assembling or the overhauling of big cryomagnets used in the LHC collider,  either the existing LHC cryomagnets or the new cryomagnet designs. For the new designs, we are running the production of small series.  These activities involves a broad range of equipment and especially CNC milling machines and lathes.

As a CNC Machine Programmer, you will:

  1. Assist with the preparation and production scheduling of the machines;
  2. Carry out preventive and corrective maintenance of machine equipment;
  3. Analyze and propose optimization of the machine programs;
  4. Study, define and formalize manufacturing processes;
  5. Choose the most suitable cutting tools to optimize the manufacturing;
  6. Carry out and monitor the machining programs;
  7. Train machine operators in procedures and processes.


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 (, 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.

In additional, you should also demonstrate:

  • Ability and willingness to share knowledge and best practices;
  • Ability to work using Computer Aided Design (CAD)  e.g. CATIA & AutoCAD;
  • Ability to work with  Computer Aided Manufacturing (CAM) software (CNC Post processors, e.g. workNC);
  • Respect the rules of metrology.

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 4585 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.

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.
    • 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 30.09.2021.
