Fibre Optics Installations Technician


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

Great technology needs great people! Join the Fibre Optics Section in the Electrical Engineering Group (EN-EL) and actively participate in the design, preparation, supervision and validation of optical fibre installations.
