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.

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization.

This is your Quest. Deepen your knowledge and expertise faster than anywhere else on earth. Take Part!


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) and actively participate in a large variety of tasks from equipment database modifications, quality control and small electrical design tasks and to work on a prestigious renovation project, namely the SPS low voltage renovation project. You will do the design of low voltage distribution networks, equipment sizing, protection studies, lighting studies and earthing studies with the objective of taking on projects of increasing complexity.

As electrical designer, you will:

  • Design electrical distribution circuits and prepare the respective design drawings;
  • Identify needs and requirements from the design managers or project managers;
  • Maintain and modify equipment databases within a team (Cabling schedules, Switchboards, Circuit breakers etc.);
  • Support the project manager in preparing technical documents;
  • Prepare bills of material for electrical-related equipment;
  • Planning and follow-up of activities.


Eligibility criteria:

  • You are a national of a CERN Member or Associate Member State;
  • You have a Master’s degree and between 2 and 6 years’ experience or PhD with up to 3 years of relevant experience in Electrical Engineering, specifically the design of electrical distribution networks or other related field;
  • You should have a working knowledge of English or French.

Skills and/or knowledge:

  • Proven experience in the design of low voltage distribution networks (selectivity, completing detailed calculation notes, knowledge of European LV standards, protection, knowledge of UPS’ and generators, protection of circuits for indirect contact, knowledge of different types of earthing systems, safety networks);
  • Design of lighting systems for buildings and external areas using DIALux;
  • A good understanding of power systems; voltage drop calculations, short circuit calculations, understanding fault levels, dimensioning of cables;
  • Proficient in AutoCAD, Dialux, E-PLAN and ElecCalc or similar software;
  • Experience in the design of medium voltage distribution networks would be a benefit.


Additional Information

What we offer: 

  • An employment contract of in principle 24 months, with a possible extension up to 36 months;
  • On-the-job and formal training at CERN as well as in-house language courses for English and/or French;
  • A monthly stipend ranging between 6050 and 6650 Swiss Francs per month (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.

You will need the following documents to complete your application:

  • A CV;
  • A scanned PDF of your most recent relevant qualification;
  • We recommend to add two recent letters of recommendation, giving an overview of your academic and/or professional achievements. You can upload these letters at the time of application if you have them to hand. You will also be provided with a link as soon as you have submitted your application to forward to your referees to upload their letters confidentially.

The earliest expected start date for selected candidates is May 2023.

Ready to take part? Then please submit your application by 23 January 2023 at  midnight (12.00 AM CEST).
