Jobbannons

At CERN, the European Organisation 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

The Engineering Department (EN) pushes back the limits of technology so that physicists can carry out their research. Within the Electrical Group of the Engineering Department (EN-EL), you will join the Electrical Project Management Section (EPM), which is responsible for the management of projects related to the consolidation and upgrade of CERN's electrical transmission and distribution network.

Functions

You will ensure the site supervision and management for projects ranging from high voltage networks to low voltage installations, as well as:

• Supervise the onsite works for the projects of consolidation and extension of the existing electrical network, including coordination with non-electrical activities such as civil engineering, transport and handling, cooling and ventilation, IT systems carried out by other groups at CERN.
