Full Job Description
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 You are expected to possess the foundational knowledge required to: * 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. * Produce electrical design drawings, including single-line diagrams. * Prepare bills of materials for electrical equipment and installations. More information [here](https://videos.cern.ch/record/2301705). Your profile * Proven hands-on experience in the design of low voltage distribution networks (LV calculation notes, equipment dimensioning, selectivity studies and protection). * Proven experience in short circuit calculations. * Proven experience in selectivity studies. * Experience in the design of lighting systems for buildings and external areas using DIALux is beneficial to the role. * Experience in secondary design with E-PLAN or similar software is beneficial to the role. * Experience in the design of medium voltage distribution networks is beneficial to the role. Skills Required skills and knowledge: * Knowledge of LV st
