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


The Engineering Department (EN) pushes back the limits of technology so that physicists can carry out their research. Within the Electrical Engineering (EL) group of the EN department, you will join the Cabling Services Section which is responsible to install copper signal cables, standardised racks and DC power cables for magnets in the accelerators and experimental areas. The section provides engineering installation support to the CERN users, centralises their cabling requests.

Are you an experienced electrical technical engineer looking to take part in the design, deployment, maintenance and extension of critical DC-power cabling installations in a large industrial setting? Contribute your skills to the magnet-powering infrastructures that constitute CERN's accelerator complex. Take part!


As an Electrical Technical Engineer you will actively contribute to the continuous expansion, consolidation and maintenance of CERN's DC-power cabling installations constituting the infrastructure for the major magnet powering systems of the various accelerators. This includes taking part in CERN's current leading project: the High-Luminosity Large Hadron Collider (HL-LHC) Project.

You will:

  • Take responsibility for Direct Current (DC) cabling activities within projects, including both air-cooled and water-cooled power cables. Contribute to similar activities for Alternating Current (AC), signal cabling, fibre optics, as required;
  • Carry out DC-cable design according to the requirements for the DC-circuits in the accelerators;
  • Draw-up technical specifications and manage the tendering process as well as the industrial supply and installation contracts;
  • Define cabling components, installation methodologies, testing procedures, naming conventions, and database strategies for data organisation;
  • Organize DC-power cabling campaigns on the CERN site, requiring close and frequent on-site interactions with contractors and CERN users from other groups/departments;
  • Prepare statistics and forecasting, and follow-up project costs and financial plans;
  • Coordinate and train a team of technicians.


Bachelor's degree or equivalent relevant experience in the field of electrical Engineering or a related field.


The experience required for this post is:

  • Demonstrated experience in the field of electrical power distribution cabling
  • Proven experience in cable installation and testing.
  • Proven experience dealing with contractors.
  • Experience in medium size Project Management.
  • Experience in managing teams would be an asset.
  • Experience in water-cooled cables would be an asset.
  • Knowledge in electrical network and related equipment would be an asset.

Technical competencies:

  • Construction, test and commissioning of electrical circuits and networks: in particular, installation and decommissioning of signal and power cabling; assembly of connectors/lugs including related installation techniques and tools;
  • Design and manufacturing of high-voltage cables and connectors: (high/ low voltage cables and connectors, in particular power cables;
  • Design and analysis of mechanical structures: in particular design and installation of cables trays, racks and respective supports;
  • Organisation, planning and control;
  • Contracts, maintenance and medium size project management.

Behavioural competencies:

  • Managing Self: taking initiative beyond regular tasks and making things happen;
  • Achieving Results: driving work / projects along and seeing them through to their conclusion;
  • Solving Problems: anticipating obstacles; assessing alternative solutions in order to have a fall-back plan Identifying, defining and assessing problems, taking action to address them;
  • Working in Teams: building and maintaining constructive and effective work relationships Working well in groups and readily fitting into a team; participating fully and taking an active role in team activities;
  • Communicating Effectively: listening actively to others and letting others speak Ensuring that information, procedures and decisions are appropriately documented;

Language skills:

  • Spoken and written English: ability to understand and speak the language in professional contexts and ability to draw-up technical specifications and to make oral presentations.
  • Basic knowledge of French or willingness to acquire it.
