Mechanical/Electromechanical Technician - ATLAS ITk Upgrade

Job Posting Organization:
CERN, the European Organization for Nuclear Research, is a leading scientific research institution established in 195

• It is located in Geneva, Switzerland, and is known for its groundbreaking work in particle physics. CERN employs over 2,500 staff members and collaborates with thousands of scientists from around the world, representing more than 100 nationalities. The organization operates in multiple countries and is dedicated to pushing the boundaries of science and technology, fostering an environment of innovation and collaboration.

Job Overview:
The position of Mechanical/Electromechanical Technician within the CERN ATLAS Team is crucial for the construction of the future silicon ATLAS Inner Tracker (ITk). The role involves working closely with the CERN Detector Technologies (DT) team, focusing on the design, prototyping, and assembly of the Pixel Outer Barrel for the ITk. The technician will be responsible for hands-on participation in the production, testing, and installation of the Pixel Outer System services and their support structures. This includes supporting the design and manufacturing of temporary services for testing during the integration of the Pixel Detector, as well as documenting manufacturing and installation procedures to ensure traceability. The technician will also contribute to the integration of the Pixel Outer System into the ITk in the cleanroom and assist in the installation of the ITk in the ATLAS cavern.

Duties and Responsibilities:
The duties and responsibilities of the Mechanical/Electromechanical Technician include:

• Participating in the production, testing, and installation of the Pixel Outer System services and their support structures, such as trolleys.
• Supporting the design, manufacturing, and installation of temporary services and infrastructure for testing during the integration of the Pixel Detector.
• Engaging in hands-on integration of the Pixel Outer System and its insertion into the ITk in the SR1 cleanroom, contributing to the development and fabrication of the corresponding tooling.
• Assisting in the ITk installation in the ATLAS cavern, preparing Pixel services for installation and making connections after insertion.
• Documenting manufacturing and installation procedures, as well as quality control information of tools and production parts to ensure traceability.

Required Qualifications:
Candidates must possess a higher technical diploma or equivalent relevant experience in Precision Mechanics or a related field. They should have demonstrated experience in conventional precision machining of metallic and non-metallic parts, using both conventional and non-conventional methods. A good understanding of mechanical and electrical drawings, including geometrical tolerance specifications, is essential. Additionally, candidates should have experience in the assembly of complex, high-precision mechanical systems with high-quality standards, as well as proven experience in manufacturing and installation of cable bundles and harnesses. Familiarity with structural joining techniques, particularly adhesive bonding and orbital welding, is also required.

Educational Background:
The educational background required for this position includes a higher technical diploma in Precision Mechanics or a related field. Equivalent relevant experience may also be considered acceptable. Candidates should have a solid foundation in mechanical engineering principles and practices, particularly as they relate to precision mechanics and electromechanical systems.

Experience:
Candidates should have demonstrated experience in the field, particularly in conventional precision machining and the assembly of complex mechanical systems. Experience with CNC machines and CAD software, ideally Catia V5, is highly desirable. Previous experience in CAD-CAM programming, preferably using WORKNC, will be considered an asset. The role requires a strong understanding of mechanical and electrical drawings and the ability to work with high precision and quality standards.

Languages:
The position requires proficiency in spoken and written English or French, with a commitment to learn the other language. This bilingual requirement is essential for effective communication within the diverse team at CERN.

Additional Notes:
The position is a limited duration contract for 3 years, with the possibility of extension up to 8 years and eligibility for an indefinite contract tenure. The working hours are 40 hours per week, and the job is fully onsite. The role may involve work in radiation areas, interventions in underground installations, and may require a valid driving license. Candidates should be prepared to work during nights, Sundays, and official holidays as needed by the organization. CERN offers a competitive salary that is tax-free, along with 30 days of paid leave per year, comprehensive health insurance coverage, family allowances, and a relocation package depending on individual circumstances.
