Experienced Electrical Technician - Cable systems (EN-EL-CS-2025-121-LD)

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.

Job Description

Introduction

The Engineering Department (EN) pushes back the limits of technology so that physicists can carry out their research. Within the Electrical Engineering (EL) group of the EN department, you will join the Cabling Services Section which ensures electrical interconnections, both signal and power, for numerous components crucial to CERN operation.

Are you an experienced Electrical Technician looking to take part in the design, planning and supervision of the installation of control and power cable systems in a large industrial setting? Join in and contribute to the infrastructures that form the backbone of CERN's accelerator complex. Take part!

Functions

As an Electrical Technician within the Cabling Section, you’ll play a key role in expanding, strengthening, and maintaining CERN’s control and power cable installations, required for various systems within the CERN accelerators, such as alarm systems, process control systems, beam instrumentation, and magnet powering systems.

You will mainly contribute to the Personnel Safety System Consolidation (PSS-CONS) project, which involves refurbishing the Personnel Safety Systems of the Large Hadron Collider (LHC). Your responsibilities will include preparing the installation of approximately 500 km of cabling to interconnect safety systems, as well as supervising the work carried out by an external contractor.

You will:

• Analyse cable installation requests and liaise with requestors to obtain any missing information;
• Conduct the necessary studies, including the definition of the cable types, the connectors assembly, the wire conventions, the routing and the mechanical supports, in collaboration with users and considering the constraints of the work environment;
• Establish bills of quantities and budgets;
• Organise cabling and de-cabling campaigns with external and internal coordination stakeholders (i.e contractors, transport and handling service, coordination team);
• Ensure the preparation of detailed work documentation (e.g., drawings, cable lists, connector assembly procedures, test procedures);
• Carry out risk assessments related to the execution of cabling work, identifying potential hazards and defining mitigation measures to ensure safety and compliance with CERN standards;
• Manage the logistics required for cabling activities, such as material delivery, scaffolding setup, and site access;
• Organize and manage worksite meetings;
• Monitor and report the progress, the safety and the quality of the works;
• Perform inspection, testing and acceptance of completed work;
• Participate to the standby duty service.
