Job Overview:
The Mechanical Engineer position within the ALICE Technical coordination-team" style="border-bottom: 1px dotted #007bff !important;">Coordination team at CERN is crucial for addressing the mechanical-engineering workload associated with the upcoming Long Shutdown periods of the Large Hadron Collider (LHC). This role involves contributing to the installation activities for the ALICE detector upgrade programme, specifically during LS3 and LS4, which includes the installation of new components such as the beam pipe and silicon tracker. The engineer will work closely with a multidisciplinary team, providing mechanical engineering support and on-site supervision during maintenance periods. The role also encompasses the design and construction of the new ALICE 3 detector system, ensuring compliance with safety requirements and performance standards. The successful candidate will engage with various stakeholders, including detector experts and external companies, to facilitate the successful execution of projects.

Duties and Responsibilities:
The Mechanical Engineer will be responsible for participating in the ALICE detector upgrade programme for LS3, which includes the installation of the new beam pipe, silicon tracker, and forward calorimeter. Key responsibilities include providing mechanical engineering support and on-site supervision during programmed maintenance periods, defining the experiment layout for the ALICE3 upgrade programme for LS4, and designing detector structures while conducting structural analyses to ensure compliance with safety and performance standards. The engineer will also support the ALICE Technical Coordination team in supervising designers and technicians, coordinating activities across different technical fields, and ensuring effective communication with stakeholders.

Required Qualifications:
Candidates must possess a Master's Degree or equivalent relevant experience in Mechanical Engineering or a related field. They should have proven experience in the design, construction, and assembly of mechanical systems, as well as proficiency in using CATIA for CAD design and ANSYS for structural analysis. Experience in supervising technical engineers and technicians, along with the ability to coordinate work with external companies and contractors, is essential. Technical competencies in the design and analysis of mechanical structures, numerical modelling in solid mechanics, and knowledge of non-metallic composites are also required.

Educational Background:
A Master's Degree in Mechanical Engineering or a closely related field is required for this position. Equivalent relevant experience may also be considered, but a strong educational background in mechanical engineering principles is essential for success in this role.

Experience:
The ideal candidate should have substantial experience in the design, construction, and assembly of mechanical systems. Experience working in a multidisciplinary team is crucial, particularly in roles that involve supervision of technical engineers and technicians. Proven ability to coordinate activities involving different technical fields is also necessary, as the role requires collaboration with various stakeholders and external contractors.

Languages:
Fluency in spoken and written English is mandatory, and candidates should demonstrate a commitment to learning French, which is considered beneficial for the role.

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 tenure. The job requires a full-time commitment of 40 hours per week and involves working in radiation areas and underground installations. Flexibility is required, as the role may involve working during nights, Sundays, and official holidays based on organizational needs. The job grade is classified as 6-7, and the reference for this position is EP-ALI-TC-2026-127-LD. CERN offers a competitive salary that is tax-free, along with comprehensive health insurance, paid leave, and a relocation package depending on individual circumstances.
