What you'll do

The Electrical Engineering Group (EN-EL) at CERN is responsible for the electrical power-distribution network (from 400 kV to 400/230V), for the fibre-optics infrastructure, and for signal and DC-power cabling for the accelerator complex.

You will join the Electrical Design and Documentation Office (EN-EL-DDO) as an Electrical Designer. Working under the guidance of senior design managers, you will contribute to several strategic CERN projects, including the electrical consolidation of the North Area, SPS LV electrical substations and the renovation of obsolete medium-voltage protection relays in the LHC.


With the support of a senior designer, you will do the design of low voltage distribution networks, equipment sizing, protection studies and lighting studies with the objective of taking on projects of increasing complexity.


Your responsibilities

  • Perform short-circuit calculations.
  • Conduct protection coordination and selectivity studies.
  • Design electrical power distribution systems and circuits.
  • Prepare calculation reports, lighting studies, and earthing studies.
