Electromechanical Technician; EP-ATL---LD

Electromechanical Technician (EP-ATL-SO--LD)

Contract

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.

As a versatile electromechanical technician with experience in installing and maintaining a wide range of equipment, you will play a key role in the infrastructure upgrade and implementation of the ATLAS upgrade project (2026–2030). As part of the ATLAS Technical Coordination team, you will liaise with detector teams, contribute to the decommissioning of existing equipment, and participate in the installation and commissioning of the new rack infrastructure, while supporting detector teams in their installation work.

• Participate in the decommissioning of existing electronics racks.
• Contribute to the installation of new racks in the underground service caverns, including rack cooling and power distribution systems as well as ventilation turbines, to meet the future needs of the ATLAS detector systems.
• Participate in the commissioning of the racks and be responsible for the maintenance of rack cooling and power distribution systems, including spare parts management.
• Contribute to the assembly, installation, and maintenance of rack ventilation turbines.
• Support the upgrade and maintenance of the PLC-based Detector Safety System (DSS) hardware.
• Participate in cable routing and in the installation of electromechanical equipment for ATLAS detector infrastructure.
• Support the maintenance of common environmental control and monitoring devices (e.g., webcams, temperature, and humidity sensors, etc.).
• Support the operation, maintenance and refurbishment of the ATLAS surface facilities.
• Coordinate, in collaboration with the group responsible for Access & Alarms, the maintenance of the sniffer system used to monitor the concentration of smoke or flammable gas.
• Be part of the Detector Safety System (DSS) on‑call team.

Higher technical diploma or equivalent relevant experience in the field of Electromechanics or a related field.

• Demonstrated experience in the maintenance and assembly of electromechanical systems.
• Proven knowledge of electrical distribution, cabling, sensors and water cooling is required.
• Knowledge of ventilation and sniffer systems is an advantage.
• Proficiency in working on various projects in parallel.
• Experience in scheduling and coordinating maintenance work is an advantage.
• Construction, test, and installation of electromechanical equipment and systems.
• Operation and maintenance of electromechanical equipment and systems.
• Operation and maintenance of electrical circuits and networks.
• Electromechanical testing.
• Working in Teams: building and maintaining constructive and effective work relationships.
• Demonstrating Flexibility: readily accepting new tasks or work/projects.
• Achieving Results: delivering high quality work on time and fulfilling expectations.
• Managing Self: working well autonomously; taking on activities and tasks without prompting.

Spoken and written English, with a commitment to learn French.
