Mechanical Technician

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading research institution established to explore the fundamental structure of the universe. Founded in 1954, CERN has grown to employ over 2,500 staff members and collaborates with thousands of scientists from around the world. The organization operates in multiple countries, primarily in Europe, and is known for its groundbreaking work in particle physics, utilizing the world's largest and most complex scientific instruments to study fundamental particles and their interactions.

Job Overview:
The Mechanical Technician position within CERN's Engineering Department (EN) focuses on the cooling and ventilation systems essential for the operation of CERN's accelerator complex and experimental areas. The successful candidate will join the LHC Section, responsible for the operation and maintenance of these critical systems. The role involves supervising installation work, commissioning new systems, upgrading existing systems, and consolidating older systems. The technician will be expected to contribute their expertise in industrial cooling, ventilation, and refrigeration systems to ensure the smooth operation of complex cooling plants in a unique scientific environment. This position requires a proactive approach to planning, coordinating, and executing maintenance activities, as well as interacting with clients to address their needs effectively.

Duties and Responsibilities:
As a Mechanical Technician, your responsibilities will include: planning and coordinating maintenance activities using the CMMS system; performing preventive and corrective maintenance on cooling and ventilation systems; ensuring the proper operation of refrigeration systems; interacting with clients regarding equipment under your responsibility; proposing solutions for modifications or renovations; technically coordinating contractors' work in compliance with standards; contributing to projects from design to commissioning; maintaining up-to-date technical documentation; ensuring adherence to safety rules; participating in stand-by service; and regularly reporting on activity progress, issues, schedules, and costs.

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 of 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. Initial experience with compressed air systems is also beneficial. Candidates should have a solid understanding of HVAC plants, cooling water systems, and electrical circuits.

Educational Background:
A higher technical diploma in refrigeration, mechanical engineering, or a related field is required. Equivalent relevant experience may also be considered in lieu of formal education. Candidates should have a strong foundation in mechanical systems and engineering principles, particularly as they relate to cooling and ventilation technologies.

Experience:
The position requires demonstrated experience in the maintenance, operation, and installation of ventilation and cooling systems. Candidates should have a strong background in industrial refrigeration systems and experience in coordinating technical work with external contractors. Familiarity with CMMS tools and low-voltage electrical systems is also necessary, along with initial experience in compressed air systems.

Languages:
Fluency in spoken and written English or French is mandatory, with a commitment to learn the other language. Proficiency in both languages is advantageous and will enhance communication within the diverse work environment at CERN.

Additional Notes:
This position is a limited duration contract for 5 years, with the possibility of extension up to 8 years and eligibility for an indefinite contract thereafter. The role requires full-time onsite work, with a 40-hour work week. Candidates should be prepared for participation in regular stand-by duties, including nights, Sundays, and official holidays, as well as work in radiation areas and underground installations. A valid driving license is required, and candidates must obtain medical clearance due to the occupational health risks associated with the position. The job grade is classified as 3-4, and the reference for this position is EN-CV-LHC-2026-8-LD.
