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 http://home.cern.

Job Description


The Engineering Department (EN) pushes forwards the limits of technology so that physicists can carry out their research. Within the Electrical Engineering (EL) group of the EN department, you will join the Electrical Works and Services (EWS) section, which is in charge of the delivery of electrical work, the commissioning of new electrical installations, and the operation of the CERN electrical transmission and distribution network.

Are you a qualified and proactive electrical technician, specialized in the commissioning of electrical equipment and the operation of electrical networks?

Contribute your skill and experience to the operation, maintenance, consolidation and expansion of CERN’s complex electrical transmission and distribution network, at the heart of one of the world’s most complex and exciting scientific experiments. Join the CERN electrical engineering team. Take part!


As an Electrical Technician in the Electrical Works and Services (EWS) section, you will work on the operations of high and low voltage electrical equipment and networks.

You will:
