At CERN, the European Organisation 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.

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.
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:
Knowledge of LV standards, LV protection, indirect contact protection, knowledge of different types of earthing systems and safety networks).
A good understanding of power systems; voltage drop calculations, short circuit calculations and dimensioning of cables and equipment.
Experience with low voltage design calculation tools (ElecCalc, Caneco or similar software).
Proficiency in AutoCAD or similar.
Language skills:
Spoken and written English, with a commitment to learn French.
Eligibility criteria:
You have a professional background in Electrical Engineering (or a related field) and have either:
a Master's degree with 2 to 6 years of post-graduation professional experience;
or a PhD with no more than 3 years of post-graduation professional experience.
You have never had a CERN fellow or graduate contract before.
This position involves:
Work in Radiation Areas.
Interventions in underground installations.
A valid driving licence.
What we offer
A monthly stipend ranging between 6,372-7,004 Swiss Francs (net of tax).
Coverage by CERN's comprehensive health scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund.
Depending on your individual circumstances: installation grant; family, child and infant allowances; payment of travel expenses at the beginning and end of contract.
30 days of paid leave per year.
On-the-job and formal training at CERN as well as in-house language courses for English and/or French.
We've signed the Gradcracker feedback pledge.
(This means that we will supply feedback if requested after an interview.)
