ATLAS Detector Installation Technician

As a Junior Mechanical Technician, you will support experienced colleagues in mechanical installation and integration activities on the ATLAS detector and its infrastructure during Long Shutdown 3 (LS3), gaining hands-on experience in a cutting-edge experimental physics environment.

Responsibilities

• 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.
• Manufacture parts and tooling using conventional machining techniques, such as drilling, milling, and turning, when required.

Requirements

• 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.
• Studies focused on Mechanical Engineering or equivalent.
• You are a national of a CERN Member State or Associate Member State (excluding Pakistani and Lithuanian nationals for 2026 start date).
• By the application deadline, you have a maximum of 2 years of professional experience since graduation in a technical or administrative field and your highest educational qualification is a general secondary education diploma or a shorter non-university degree.
• You cannot hold a bachelor’s degree, master’s degree or PhD.
• You have never had a CERN fellow or graduate contract before.
• A valid driving licence.
• Medical clearance required due to occupational health risks.
• Willingness to work in radiation areas, underground installations, and during nights, Sundays and official holidays when required.
