What you'll do: You will play a key role in the design, prototyping, construction, and integration of the mechanical structures and services for the innermost region of the CMS detector at CERN. This includes beam-pipe support structures, tracker bulkheads, beam-luminosity and beam-background monitors, and their associated services. The work will culminate in the equipment installation and commissioning at the end of the Long Shutdown 3 of the LHC.
Your responsibilities: - Prepare 3D models and technical drawings and perform thermo-mechanical analyses of complex mechanical components and assemblies.
- Contribute to component procurement and oversee fabrication of mechanical parts, including related quality assurance.
- Lead and supervise the assembly of mock-ups, prototypes, and final versions of support structures for the CMS innermost region.
- Assist with the integration and testing of the Inner Tracker and Luminosity Monitors at CERN.
- Support and supervise colleagues from collaborating institutes participating in integration activities at CERN.
Your profile: - Proven experience in design of complex mechanical components and assemblies using 3D CAD tools.
- Experience with structural and thermal simulations using finite-element analysis.
- Experience in construction, assembly, and quality control of mechanical systems.
- Demonstrated ability to work effectively within a multidisciplinary team, establishing and maintaining constructive and effective working relationships with a diverse range of colleagues.
- Master's Degree or equivalent relevant experience in the field of Mechanical Engineering or a related field.
Your skills: - Design and analysis of mechanical structures. - Production of 2D drawings and 3D models. - Knowledge and application of numerical modelling in solid mechanics. - Manufacturing of mechanical parts. - Builds and maintains constructive and effective work relationships. - Shares knowledge and expertise freely and willingly with others; coaches others to ensure knowledge transfer. - Creates a common mind-set and promotes team spirit. - Spoken and written English, with a commitment to learn French.
