Fibre Optics Technician (EN-EL-FC-2020-74-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


The Engineering Department (EN) pushes back the limits of technology so that physicists can carry out their research. Within the Electrical Engineering Group (EL) of the EN department, you will join the Fibre Optics and Cabling Section (FC), which is in charge of CERN's optical fibre infrastructure, ensures the technical expertise in the field of fibre 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.

Are you a qualified fibre optic technician with experience in preparing installation works and supervising the deployment of fibre optics infrastructures? Contribute your skills to the infrastructure for the major communication systems that constitute CERN's accelerator complex. CERN, take part!


As a Fibre Optic Technician in the EN-EL-FC Section, you will be responsible for processing optical cabling requests and for conducting entire optical cabling campaigns in the CERN sites.This position requires close and frequent interactions with contractors and CERN internal users from other departments.

This will involve:

  • Establishing optical fibre installation requirements in collaboration with the CERN users;
  • Taking part in defining the optical fibre link architecture including fibre and duct types and connections;
  • Contributing to periodic reviews of optical cabling activities and propose innovative solutions for optical cabling and tests.
  • Preparing the necessary computer-based work files for the contractors and users;
  • Studying, proposing, implementing and monitoring work execution schedules and ensure compliance with the required activities;
  • Organizing and managing work site meetings and discuss cabling campaign planning with contractors;

  • Organizing the documentation of the installations and preparing technical notes summarizing the work done;


Higher technical diploma in the field of Fibre Optics or a related field.


  • Demonstrated experience in the field of optical cabling technology. Preferably in an industrial environment;
  • Substantial experience in the preparation of work files, as well as in work supervision and acceptance of optical installations;
  • Additional experience in the field of electrical cabling would be an asset;
  • Experience in coordinating the work of a team of technicians would be an asset;

Technical competencies:

  • Organisation, planning and control: technical supervision of contractors, quality of the worksites and worksite meetings;
  • Practical knowledge of optical cabling techniques, in particular optical cabling by blowing;
  • Practical knowledge of optical fibre connectors and connector-fitting (e.g. by splicing);
  • Knowledge of optical transmission fundamentals;
  • Practical knowledge of tests and measurement techniques in the fibre optics domain;

Behavioural competencies:

  • Managing Self: working well autonomously; taking on activities and tasks without prompting Taking initiative beyond regular tasks and making things happen
  • Achieving Results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind
  • Solving Problems: identifying, defining and assessing problems, taking action to address them
