Tips: tailor your CV to show cross‑functional leadership, schedule management, risk mitigation, on‑site coordination, safety experience, and ability to deliver under LS3 timelines; ensure a valid driving licence, willingness to obtain medical clearance, and apply by 25.10.2026 at 23:59 CEST.

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. 

Job Description

Introduction

As ATLAS Muon LS3 Integration and Installation Manager you will play a key role in the preparation and execution of activities during Long Shutdown 3 (LS3). You will be responsible for ensuring effective coordination across all ATLAS Muon sub-projects. You will closely follow daily work at P1 for Muon upgrade and maintenance projects, monitor progress, and take action to keep Muon activities on schedule. The role requires close collaboration with various ATLAS Muon sub-projects, ATLAS Technical Coordination (TC), and other relevant CERN groups. You will serve as the primary interface between the Muon projects and ATLAS TC, ensuring coherent planning, efficient execution, and comprehensive reporting of all activities.
During Long Shutdown 3 (LS3, 2026–2030), the ATLAS Muon detector will undergo significant upgrades, including the installation of new detector systems and extensive maintenance of existing detector components. As the ATLAS Muon LS3 Integration and Installation Manager, you will play a central role in planning, coordinating, and monitoring these activities.
