Mechanical Engineer - CMS Innermost Region (EP-CMS-ID-2026-152-LD)

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. 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.

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature.
