Job Details

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


Are you passionate about technical work and interested in joining the operational activities of our cabling services for the experiments and experimental areas? Do you have solid experience being responsible for an industrial cabling workshop? Do you have experience with work site supervision in the electrical field? Are you a qualified and proactive electrical technician, willing to contribute to a unique environment at the heart of one of the world's most complex and exciting scientific experiments? Then, this opportunity is for you - join the largest particle physics research laboratory in the world. CERN, take part!

The Beams Department (BE) provides CERN with the unique competencies required for the conception, design, survey, alignment, control and operation of accelerators, accelerator test facilities, secondary beam lines and experimental areas. It also invests heavily in training new generations of physicists, engineers and technicians in related fields.

Within the BE department, you will work for the Experimental Areas (EA) group, which is responsible for the beamlines, infrastructure and management of CERN's experimental areas and provides engineering support and services including associated contracts. EA is furthermore supporting the LHC experiments as well as participating in and partly hosting the management of a number of CERN wide projects.

Acting as direct contact to both our internal CERN clients, as well as related suppliers, after an initial training period your will become responsible for the electrical switch board production. You will aim at the highest customer satisfaction, in accordance with CERN safety rules, while continuously improving and developing quality and electric testing procedures. The work is carried out together with scientists and technicians working on the CERN experiments from all over the world, and staff of CERN groups requiring support, both in the workshop as well as on the field.


As a technician, you will take part in all the life-cycle of cabling activities of complex HV/LV signal systems from the order to the installation and verification.

Your functions will:

  • Perform and/or supervise the production of integrated systems such as electrical cubicles, distribution- and switchboards, as well as crates and racks: from the feasibility studies (selection of cross section, electrical components, enclosures, drafting of specifications, quotations, qualification tests) to the execution (planning, definition of the necessary resources, ordering of the equipment, technical supervision of the teams on site, electrical lock out, hazard management, tests, final acceptance, and invoicing) in accordance applicable norms.
  • Supervise the production and manufacture cables and electrical assemblies internally or through subcontracting, addressing client specifications, assembly/production procedures and execution.
