• Provide on‑site mechanical engineering supervision during scheduled maintenance periods.
• Define experiment layout for the ALICE 3 upgrade, integrating detectors, services and infrastructure.
• Design metallic and carbon‑composite structures and perform structural analyses for mechanical, thermal and dynamic loads.
• Coordinate with detector experts, external companies, and CERN technical support teams.
• Supervise designers and technicians in daily tasks.

Required profile

• Master’s degree or equivalent in Mechanical Engineering or a related field.
• Proven experience in design, construction and assembly of mechanical systems.
• Experience working in multidisciplinary teams and supervising technical staff.
• Ability to coordinate work with external contractors.

Required skills

• Proficiency with CATIA for CAD design.
• Knowledge of ANSYS for structural analysis.
• Design and analysis of mechanical structures.
• Numerical modelling in solid mechanics.
• Experience with non‑metallic composites.
• Production of 2D drawings and 3D models.
