What you'll do
We are recruiting two early-career graduates for Mechanical Technician positions within the CMS experiment. Both positions involve hands-on mechanical work and close collaboration with technicians, engineers, and physicists, but each will have a different main area of responsibility:
- One position will join the Electromagnetic Calorimeter (ECAL) team, supporting the refurbishment of the barrel electromagnetic calorimeter and covering a large panel of activities and responsibilities, from mechanical work and the handling and assembly of detector parts to logistic activities.
- The second position will join the CMS Technical Coordination crew, supporting mechanical activities for the CMS detector and its infrastructure, including maintenance, upgrades, tooling, and heavy-lifting operations.
