Telecom and Network Infrastructure Technician (IT-FCS-DO-2026-173-LD

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.

Join the Deployment and Operations team in the Communication Systems and Fabric Group and contribute to the reliable connectivity that supports one of the world’s leading scientific research environments. You will coordinate and follow up telecom and network infrastructure works across CERN sites, working with contractors, users and technical teams to plan installations, check quality, ensure safety and maintain accurate documentation.

We welcome candidates with hands‑on experience in cabling, telecom, electrical, industrial infrastructure or network installation environments who are motivated to develop in a unique international setting.

• Review cabling requests and collaborate with requesters to clarify needs when necessary.
• Help define suitable cable types and routes, working with users and taking into account the local environment.
• Coordinate cabling and de‑cabling activities with both internal teams and external partners (e.g. contractors).
• Prepare clear and practical documentation to support the work (such as drawings and technical plans).
• Contribute to safe working practices by identifying potential risks and supporting the implementation of mitigation measures in line with CERN standards.
• Support the organisation of logistics for cabling activities, including materials, access, and required equipment.
• Participate in worksite coordination and follow‑up meetings.
• Track progress and help ensure that work is carried out safely and with good quality.
• Take part in inspections and acceptance of completed work, and help keep infrastructure records up to date.

Higher technical diploma or equivalent relevant experience in the field of Telecommunications, Information & Communication Technologies, Electric or a related field.

• Experience in telecom, network, electrical, industrial or technical infrastructure installation environments.
• Ability to coordinate work on site with contractors, users, or technical teams.
• Good understanding of safety, quality and documentation practices.
• Ability to read or produce basic technical documentation, drawings or work instructions.
• Experience with structured cabling, fibre, copper, coaxial or radio/leaky‑feeder systems is desirable.
• Work experience in complex industrial, underground, controlled‑access or safety‑regulated environments is desirable.
• Experience with acceptance testing, certification or quality checks of cabling installations is desirable.
• Contractor follow‑up or worksite coordination experience is desirable.
• Speaking French would be an advantage.

• Organisation, planning and control.
• Specification and follow‑up of technical aspects of a contract.
• Project management.
• Use of office software packages.

• Achieving Results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.
• Communicating Effectively: delivering presentations in a structured and clear way; adjusting style and content to the audience; responding calmly and confidently to questions.
• Solving Problems: assimilating large quantities of information, identifying key issues and formulating conclusions clearly and concisely.
• Managing Self: taking initiative beyond regular tasks and making things happen.
• Working in Teams: contributing to promoting a positive atmosphere in the team through an optimistic and constructive attitude; addressing issues.
