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

Introduction

Are you an experienced Telecom Engineer who enjoys innovative network and telephony projects? Take an active role in CERN’s Telecom and Radio Section, joining a dynamic team using cutting edge technologies, for projects related to fixed telephony, mobile, radio and IoT services. Work at the heart of telecommunication, at the largest particle physics lab in the world. CERN, take part!

You will join:

The Communication Systems (CS) Group that is responsible for all aspects of network and telephony provision at CERN. We support a campus network (cabled and Wi-Fi) with over 20,000 active devices, a 5Tb/s non-blocking switching fabric for a data centre with over 10,000 servers, more than 4,000 of which with 10Gb/s interfaces, and external connections including multiple trans-border 100Gb/s circuits. The Group also operates its own fixed telephone system (12000 connections), dedicated mobile telephony services (6500 subscriptions), a TETRA digital radio system (500 terminals) and a LoRaWAN network.
