Job Overview:
The Mechanical Engineer position at CERN involves significant responsibilities during the Long Shutdown 3 (LS3) period from 2026 to 2030, focusing on the upgrade of the ATLAS detector. This role requires the engineer to oversee the design and integration of mechanical systems, ensuring that all aspects of the detector's mechanical components are effectively managed. The engineer will serve as a critical interface between the ATLAS Technical coordination-team" style="border-bottom: 1px dotted #007bff !important;">Coordination team and the various detector upgrade teams, particularly in relation to mechanical integration activities. The position demands a proactive approach to managing the design, installation, and coordination of mechanical components, as well as the ability to work collaboratively with international teams to achieve project goals. The successful candidate will be involved in the assembly and installation of the detectors, ensuring that all mechanical interfaces are properly defined and managed throughout the upgrade process.

Duties and Responsibilities:
The Mechanical Engineer will be responsible for overseeing the design of all mechanical aspects of the ATLAS detector system, collaborating with global institutes to produce deliverables. Key duties include defining and managing mechanical interfaces between the detector and its infrastructure, supervising the production of 3D integration models, and ensuring compliance with relevant design envelopes. The engineer will develop transport and underground installation sequences, design installation tooling, and support the detector team in coordinating the production of mechanical components. Additionally, the role involves participating in the assembly of detectors in clean room environments, supervising the installation of service infrastructure, and ensuring that all installations align with commissioning needs. The engineer will also be responsible for managing multiple projects simultaneously and effectively communicating with various stakeholders.

Required Qualifications:
Candidates must possess a Master's degree or PhD in Mechanical Engineering or a related field, or equivalent relevant experience. Solid experience in mechanical design, including proficiency in 3D modeling and the creation of manufacturing drawings, is essential. Proven expertise in the installation of high-technology equipment, mechanical calculations, and Finite Element Analysis is required. The ideal candidate should have experience in writing installation procedures, project management, and coordinating teams of designers and technicians. A background in performing a variety of engineering tasks and managing multiple projects in parallel is advantageous, as is experience working within international and multidisciplinary teams.

Educational Background:
A Master's degree or PhD in Mechanical Engineering or a closely related field is required for this position. Candidates with equivalent relevant experience may also be considered. The educational background should include a strong foundation in mechanical design principles, engineering practices, and relevant technical competencies that align with the responsibilities of the role.

Experience:
The position requires solid experience in mechanical design, particularly in the context of high-technology equipment installation. Candidates should have a proven track record of managing engineering projects, including planning, procurement, and reporting. Experience in coordinating teams and performing a variety of engineering tasks is essential, with a preference for candidates who have worked on similar projects in international settings.

Languages:
Fluency in spoken and written English is mandatory, as it is the primary working language at CERN. Candidates should also demonstrate a commitment to learning French, which is beneficial for communication within the organization and the local community.

Additional Notes:
This 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 role requires full-time onsite work, with a standard working hours of 40 hours per week. Candidates should be prepared for work in radiation areas, interventions in underground installations, and may be required to work during nights, Sundays, and official holidays as needed. Due to the occupational health risks associated with this position, selected candidates must obtain medical clearance before a contract offer is confirmed. The job grade for this position is 6-7, and it falls under the field of Mechanical Engineering.
