Computing Technical Engineer (IT-ST-FDO-2019-18-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

Job Description


Work with us to extend our data handling systems for the LHC (Large Hadron Collider) physics programme and the whole of CERN. CERN is the birthplace of the World Wide Web and one of the world leading laboratories for particle physics! Join CERN's Storage Group in the IT Department as a Computing Technical Engineer for a unique challenge as the next step in your career. CERN, take part!

The CERN IT Storage Group (ST) is responsible to enable data access for the laboratory, most notably to archive, preserve over the long term and distribute to the worldwide scientific community the LHC experimental data. Today we operate a disk/tape hybrid system (CASTOR: optimised for archiving), several large disk farms (EOS: for data analysis) and a Ceph infrastructure. In total ST handles more than 200 petabyte of data across about 2,000 data servers (30,000 disks) and 20,000 high-capacity tapes.

The present data infrastructure has been evolved to extend its functionality and rationalise its deployment. New access protocols (POSIX file access, WebDAV) have been added to simplify data access for our clients (Linux, Mac and Windows), to increase the user experience (disconnected operations, cloud synchronisation, flexible web access) and to enable new ways to process data combining local access, batch processing and web-based data systems.
