Job Description
Job Posting Organization:
CERN, the European Organisation for Nuclear Research, was established in 1954 and is one of the world's largest and most respected centres for scientific research. With a mission to uncover the fundamental structure of the universe, CERN employs thousands of physicists, engineers, and other professionals from over 100 countries. The organization operates in multiple countries 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. CERN's commitment to diversity and inclusion is integral to its success, fostering an environment where innovation thrives and every contribution is valued.

Job Overview:
The Mechanical Technician position within the Handling Engineering Group (EN-HE) at CERN is crucial for the coordination and supervision of transport and handling operations related to the CERN accelerators and experiments. This role involves working closely with various departments to ensure the safe and efficient movement of goods, including conventional and unconventional items, as well as chemical and radioactive products. The technician will be responsible for developing special handling tools, conducting logistic studies, and ensuring compliance with safety regulations in both conventional and radioactive environments. The position requires participation in planning meetings to assess technical and resource needs, as well as the ability to propose and evaluate handling and transport solutions. The role also includes on-call duties and the necessity to work in challenging environments, including underground installations and radiation areas.

Duties and Responsibilities:
As a Mechanical Technician in the EN-HE-HH Section, your primary duties will include: coordinating transport and handling operations for the accelerators complex and experiments; collaborating with the EN-HE design office to develop special handling tools; conducting logistic studies; working with Radiation Protection Services to establish work dose planning and radiological work permits; participating in coordination and planning meetings to evaluate technical and resource needs; proposing and assessing possible handling and transport solutions; analyzing working procedures and safety assessments for specific operations; supervising on-site activities to ensure safety during operations in both conventional and radioactive environments; performing handling operations in specific situations; and participating in the on-call service.

Required Qualifications:
Candidates must possess a technical certificate or general secondary education, or equivalent relevant experience in Mechanics, Mechanical Engineering, or a related field. Extensive experience in heavy handling and transport operations is required, along with proven experience in worksite logistics and technical contract supervision. Experience working in radioactive environments and with the transport of dangerous items (radioactive and chemical products) is considered an asset. Basic knowledge of remote-handling systems is also beneficial.

Educational Background:
The educational background required for this position includes a technical certificate or general secondary education in Mechanics, Mechanical Engineering, or a related field. Candidates with equivalent relevant experience may also be considered, emphasizing the importance of practical knowledge and skills in the field.

Experience:
The position requires extensive experience as a Mechanical Technician, particularly in heavy handling and transport operations. Proven experience in worksite logistics and technical contract supervision is essential. Additionally, experience in radioactive environments and the transport of dangerous items will be advantageous, highlighting the need for a candidate who is well-versed in safety protocols and operational procedures in complex environments.

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

Additional Notes:
The position is a limited duration contract for 4 years, with the possibility of extension up to 8 years and eligibility for an indefinite contract tenure. The working hours are set at 40 hours per week, and the role is fully onsite. The selected candidate will participate in a regular stand-by duty, which may include nights, Sundays, and official holidays. The position involves working in radiation areas and underground installations, necessitating a valid driving license and the ability to work shifts as required. Due to the occupational health risks associated with this position, the selected candidate must obtain medical clearance before a contract offer is confirmed. The job grade is classified as 3-4, and the reference for this position is EN-HE-HH-2026-5-LD.
