DevOps Engineer (EP-LBC-2020-39-LD)

  • Geneva, Switzerland
  • Contract

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

Operating at the limit of currently available technology, every bit counts. If you enjoy pushing modern computing hardware to the maximum and tackling exciting challenges in a mission-critical cluster of more than 4,000 servers, working with the biggest network in any scientific installation today, then consider joining our small team of enthusiastic engineers and technicians! CERN, take part!

The LHCb experiment at CERN will host most of its readout electronics and all its IT infrastructure in a brand-new data-centre which will be at the core of LHCb’s data acquisition and control systems. This facility will operate 24/7 to serve the needs of one of the largest and most active scientific collaborations in the world.
