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
Work with us to evolve the CERN data storage systems used at the Large Hadron Collider (LHC) and at its international partners. CERN is the birthplace of the World Wide Web and one of the worldโs leading laboratories for particle physics. Join the Storage and Data Management Group (IT-SD) in CERN's IT Department as a Computing Technical Engineer for a unique challenge as the next step in your career. CERN, take part!
CERN's Storage and Data Management Group is responsible for enabling data storage and access for the laboratory, in particular the long-term archival, preservation and distribution of LHC data to a worldwide scientific community. Today we operate a heterogeneous disk and tape storage system, with several large EOS disk farms, the CERN Tape Archive (CTA) system and other storage solutions. In total the group manages more than one Exabyte of storage across about 2,000 data servers (60,000 disks) and 50,000 high-capacity tapes.
