Mechanical Technician

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading scientific research institution established to probe the fundamental structure of the universe. Founded in 1954, CERN employs thousands of physicists and engineers who work collaboratively to explore the basic constituents of matter using the world's largest and most complex scientific instruments. The organization operates in multiple countries and is known for its groundbreaking contributions to particle physics, including the discovery of the Higgs boson. CERN's mission emphasizes innovation, collaboration, and diversity, making it a unique environment for scientific advancement.

Job Overview:
The Mechanical Technician position within CERN's Engineering Department (EN) focuses on the operation and maintenance of cooling and ventilation systems crucial for the functioning of CERN's accelerator complex and experimental areas. The role involves working within the cooling and ventilation (CV) group of the EN department, specifically in the LHC Section. The technician will be responsible for supervising installation work, commissioning new systems, upgrading existing systems, and consolidating older systems. This position requires a qualified technician with specialized knowledge in industrial cooling, ventilation, and refrigeration systems, contributing to the maintenance and operation of complex cooling plants in a unique scientific environment.

Duties and Responsibilities:
As a Mechanical Technician, your duties will include planning, coordinating, supervising, and performing preventive and corrective maintenance activities on cooling and ventilation systems. You will ensure the proper operation of these systems, interact with clients regarding equipment under your responsibility, and propose solutions for modifications or renovations. Additionally, you will technically coordinate contractors' maintenance and installation work, contribute to projects from design to commissioning, maintain up-to-date technical documentation, and ensure compliance with safety rules during all interventions. Participation in a stand-by service and regular reporting on activity progress, issues, schedules, and costs will also be part of your responsibilities.

Required Qualifications:
Candidates must possess a higher technical diploma or equivalent relevant experience in Refrigeration or a related field. Demonstrated experience in maintenance, operation, and installation work on ventilation systems is essential, along with strong experience in cooling and refrigeration industrial systems. Experience in technical coordination of external contractors and familiarity with CMMS tools is required. Knowledge of low-voltage electrical systems and initial experience in compressed air systems will be advantageous.

Educational Background:
The position requires a higher technical diploma or equivalent relevant experience in the field of Refrigeration or a closely related discipline. This educational background ensures that candidates have the necessary theoretical knowledge and practical skills to effectively manage and maintain complex cooling and ventilation systems.

Experience:
Candidates should have substantial experience in the maintenance, operation, and installation of ventilation systems, as well as strong experience in cooling and refrigeration industrial systems. Experience in coordinating external contractors and using CMMS tools is also necessary. Initial experience with compressed air systems will be beneficial, as will familiarity with low-voltage electrical systems.

Languages:
Proficiency in spoken and written English or French is mandatory, with a commitment to learn the other language being highly desirable. This bilingual requirement reflects CERN's diverse working environment and the need for effective communication across various teams and projects.

Additional Notes:
This position is a limited duration contract for 5 years, with the possibility of applying for an indefinite position subject to certain conditions. The working hours are set at 40 hours per week, and the role is fully onsite. The position involves participation in regular stand-by duty, including nights, Sundays, and official holidays, as well as work in radiation areas and underground installations. Candidates must possess a valid driving license and may be required to work during nights and weekends as needed. The job entails exposure to various occupational health risks, including asbestos and radiation, necessitating medical clearance before a contract offer is confirmed. The job grade is classified as 3-4, and the reference for this position is EN-CV-LHC-2026-8-LD.
