Junior Electrical Engineer

Job Description
As a Junior Electrical Engineer within the Cabling Section, you'll play a key role in expanding, strengthening, and maintaining CERN's signal and power cable installations, required for various systems within the CERN accelerators.

In this role, you will also be closely involved in the High-Luminosity LHC (HL-LHC) programme. This major upgrade requires the installation of more than 800 km of signal cables over the next three years, offering a unique opportunity to participate in one of CERN's most ambitious and technically demanding projects.

Your Responsibilities
You will:

• Analyse requests for new cable circuits and for modification of existing ones;
• Define cables routing taking into technical constraints including cable trays occupancy, electromagnetic compatibility and safety rules;
• Ensure the compatibility between the cable type required and the selected connector;
• Revise cable lists;
• Prepare planning and cost estimation;
• Prepare execution documentation for CERN's electrical installation contractor;
• Organise, supervise and ensure safety on your worksites, requiring interactions with contractors and CERN users from other groups/departments;
• Ensure comprehensive and timely reporting;
• Contribute to the continuous improvement and optimisation of the section's processes and workflows;
• Development of quality plans and procedure.

About Us
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

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
