Job Description

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.

Functions

• Responsible for ensuring effective coordination of installation and integration activities across the Muon projects, tracking progress, identifying risks, and ensuring effective communication among all participating teams.
• Act as the liaison between the various Muon sub-projects and ATLAS TC, providing regular status updates and comprehensive documentation.
• Develop, maintain, and monitor the integrated LS3 schedule for Muon installation, integration, and maintenance activities in close collaboration with ATLAS TC team.
• Coordinate and oversee technical activities on the ATLAS Muon detectors in the UX15 cavern.
• Identify, manage, and resolve interface issues, schedule conflicts, and resource constraints across multiple projects and teams.
• Organize and chair regular ATLAS Muon LS3 coordination meetings, collect status information, and maintain an overview of ongoing and planned activities.
• Support Muon detector teams in coordinating LS3 activities to ensure timely delivery and efficient planning.
• Prepare and maintain comprehensive documentation, progress reports, and activity summaries.

Qualifications

PhD or equivalent relevant experience in the field of Physics or a related field.

Experience:

• Proven experience in coordinating activities for large-scale detector systems or comparable complex scientific installations.
• Demonstrated experience in planning and managing work program involving multiple teams and stakeholders.
• Demonstrated experience coordinating complex technical projects, managing competing priorities, and resolving planning, scheduling, and resource constraints in a multidisciplinary environment.
• Experience with safety systems and safety-related technical infrastructure.
• Familiarity with installation, integration, commissioning, or maintenance activities in large scientific facilities is considered an asset.

Technical competencies:

• Assembly and integration of detectors.
• Knowledge and application of gas based particle detection technologies.
• Testing and validation of detector, accelerator and beam line components.
• Assembly and integration of infrastructure for detectors or experimental facilities.
• Organisation, planning and control.
• Team management.

Behavioural competencies:

• Demonstrating Accountability: using openness and honesty to interact constructively with others.
• Demonstrating Flexibility: adapting quickly and resourcefully to shifting priorities and requirements.
• Solving Problems: producing workable and timely solutions that meet requirements.
