ATLAS Detector Installation Technician (EP-ATL-PO-2026-178-GRAE)

The EP-ATL-PO section plays a key role in the upgrade and maintenance of the ATLAS detector at the LHC. As a Junior Mechanical Technician, you will support experienced colleagues in mechanical installation and integration activities on the detector and its infrastructure during Long Shutdown 3 (LS3), while gaining hands-on experience in a cutting-edge experimental physics environment.

- Participate in large-scale ATLAS detector movements in the experimental cavern and in the installation of access platforms. - Support sub-detector installation activities, including handling, transport, and positioning using appropriate lifting and alignment techniques. - Prepare and set up work areas and tooling, and provide logistical support for detector interventions. - Read and interpret mechanical drawings, perform basic dimensional checks, and report progress to supervising engineers. - When required, manufacture parts and tooling using conventional machining techniques, such as drilling, milling, and turning.

- Initial hands-on experience in mechanical assembly, fitting, or maintenance. - Ability to read and interpret mechanical drawings, blueprints, and 2D/3D CAD models. - Initial experience with conventional machining techniques and workshop practices. - Basic metrology skills, including the use of calipers, gauges, and dimensional inspection tools. - Awareness of occupational health and safety principles in workshop and industrial environments.

- Follow technical procedures, assembly instructions, and work specifications. - Use of standard hand and power tools for mechanical operations. - Strong teamwork and communication skills, with the ability to collaborate in an international and multidisciplinary environment. - Rigorous, detail-oriented, and safety-conscious approach to work. - Accurately document completed work and maintain high quality standards while following technical procedures and safety requirements. - Spoken and written English or French, with a commitment to learn the basics of the other language. Eligibility criteria: - You are a national of a CERN Member or Associate Member State . - By the application deadline, you have a maximum of two years of professional experience since graduation in Mechanical Engineering or equivalent (or a related field) and your highest educational qualification is a general secondary education diploma . - You have never had a CERN fellow or graduate contract before. - Applicants with a Bachelor's, Master's or PhD degree are not eligible.
