Fiber optics Engineer in the Engineering Department (EN), Electrical Engineering Group (EL), Fibre Optics and Cabling Section (FC).

You will join:

  • The Engineering Department that provides engineering competencies, infrastructure systems, and technical coordination for the world's largest particle accelerator complex and its experimental facilities.
  • The EL Group that is responsible for CERN's electrical and optical fiber distribution networks. Its main missions are to operate, maintain, extend and renovate the electrical network from 400 kV to 400/230 V and the optical fibre infrastructure, analyse and make projections for CERN's electrical energy consumption and manage relations with the energy suppliers. The group is also in charge of modifications and extensions to the networks when required by new projects, with project studies, equipment procurement, installation, supervising and commissioning.
  • The Fiber Optics and Cabling Section (FC) that is in charge of CERN's optical fibre infrastructure, ensures the technical expertise in the field of fiber optics, and provides optical and copper signal cables, standardised racks and DC power cables for magnets in the accelerators and experimental areas. The section provides engineering support to the CERN users, centralises their cabling requests and organises the installation activities through external industrial-support contractors.         


As a Fiber Optics  Engineer in the Fiber Optics and Cabling Section, you will actively contribute to the continuous extension, maintenance, and operation of CERN's optical fiber network constituting the infrastructure for the major communication systems of the various accelerators including CERN's current leading project: the Large Hadron Collider (LHC).

This will involve:

  • Adapting to the rapid evolution of optical technology and giving expert assistance to optical fiber users.
  • Performing engineering studies of the optical fiber network in view of improving its reliability.
  • Defining optical cabling strategies, components, installation methodologies, and naming conventions.
  • Ensuring the thorough qualification and quality assurance for the installed components, including the radiation tolerance of different optical fiber types.
  • Drawing up technical specifications and managing industrial supply contracts.
  • Organizing and supervising optical fiber cabling installation campaigns on CERN sites.
  • Preparing data analysis, statistics and forecasting, defining project costs and financial plans.
  • Specifying and purchasing optical measurement equipment.


Master's degree in the field of electrical Engineering, electronics Engineering, or equivalent.
