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. 

Job Description

Introduction

Within the CERN Engineering department (EN), the Electrical Engineering (EL) group is responsible for managing CERN’s electrical distribution network, ranging from 400 kV to 400/230 V, which includes its operation, maintenance, renovation, control as well as forecasting energy consumption and handling relations with suppliers. Additionally, the group oversees the cabling infrastructure, managing everything from the installation and removal of control, water-cooled, and fiber optic cables to the maintenance of their supporting structures.
You will join the Maintenance and Operation (EN-EL-MO) section, responsible for the operation and maintenance of CERN’s electrical network, the commissioning of new installations, and the execution of small-scale electrical works.

As an experienced industrial electrical technician in the EN-EL-MO section, you will be responsible for operating and maintaining part of CERN's high- and low-voltage electrical network. 

Apply your expertise to support the operation, maintenance, consolidation and development of CERN’s electrical transmission and distribution systems, the backbone of one of the world’s largest and most powerful particle colliders. Join the CERN electrical engineering team. Take part!
