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.

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.

Requirements

  • Master's Degree or equivalent relevant experience in the field of Mechanical Engineering or a related field.
  • 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.
  • Spoken and written English, with a commitment to learn French.
  • A valid driving licence.
  • Willingness to work shift work, when required by the needs of the Organization.
  • Ability to work in Radiation Areas.
  • Ability to perform interventions in underground installations.
  • Availability to work during nights, Sundays and official holidays, when required by the needs of the Organization.
