Mechanical Technician for CMS Detector Upgrades

What you'll do As a mechanical technician, you will contribute to upgrade projects of the CMS detector, covering a broad range of responsibilities. These include workshop-based mechanical work, installation of detector systems, and the design and use of tooling for the removal and installation of CMS sub-detectors, as well as radioprotection duties in experimental areas and associated laboratories. You will also take on coordination and operational responsibilities within the CMS Technical Coordination team, working closely with sub-detector groups and CMS technical support teams. Your responsibilities Take responsibility for activities related to safety and radioprotection for subdetector removal and installation, working with CMS safety officers and subdetector teams, operating in radioprotection-classified areas, and applying safety rules. Manage a mechanical workshop, advising and assisting CMS subdetector teams, ensuring the availability and proper use of equipment and tools, and supplying consumables. Provide technical support and hands-on assistance to CMS subdetector project teams operating within the CMS laboratories at CERN, in the fields of mechanical manufacturing, assembly, structures, and welding. Take part in the development, testing, on-site installation, and on-detector operation of custom tooling for subdetectors, working with subdetector technical teams. Operate and maintain hydraulic, mechanical, and electromechanical systems. Organise and supervise the storage of subdetector equipment in CMS-reserved spaces at CERN, ensuring proper inventory and space management. Assist the territorial safety officer of the building where the mechanical workshop is located, supervising work requested on infrastructure for general safety, and using a mobile crane and forklift when needed. Serve as the technical contact for mechanical activities with subdetector teams and for space areas under your responsibility, reporting regularly to the Technical Coordination managers. Your profile Experience in radioprotection and the ability to work in classified areas. Proven ability to manage a mechanical workshop, including the use of standard machines and tools. Strong organisational skills for coordinating teamwork and on-site technical activities. Proficiency in reading 2D and 3D technical drawings and manufacturing mechanical parts accordingly; experience in producing 2D and 3D drawings is an asset. Solid background in the design, construction, and assembly of mechanical components and customised tooling. Experience in the installation of structures and the use of specialised tooling for handling large equipment. Ability to work effectively within multidisciplinary teams. Proficiency with the operation and maintenance of hydraulic, mechanical, and electromechanical systems is considered a plus. Higher technical diploma or equivalent relevant experience in the field of Mechanics or Manufacturing Methods or a related field. Trainings/certificates considered a plus: welding certificate, radioprotection formal training, hydraulic certificate. Your skills Knowledge and application of manufacturing methods and work preparation. Assembly of mechanical structures and equipment. Manufacturing of mechanical parts. Integration of mechanical systems. Team management. Knowledge of regulatory framework and best practice in radiation protection. Defines clear objectives, milestones and deliverables before initiating work/ project. Ensures that information, procedures and decisions are appropriately documented. Takes responsibility for own actions and decisions. Is willing to work on different projects simultaneously. Builds and maintains constructive and effective work relationships. Spoken and written English, with a commitment to learn French. Medical hazard Exposure to ionizing radiation and classified as category A. Exposure to electromagnetic fields under certain conditions. Exposure to risk of falling from heights during scaffolding assembly and dismantling operations. Exposure to lead. Given the occupational health risks associated with this position, the selected candidate must obtain medical clearance before a contract offer is confirmed. Employment conditions A valid driving licence. Work in Radiation Areas. Interventions in underground installations. Shift work, when required by the needs of the Organization. Work during nights, Sundays and official holidays, when required by the needs of the Organization. Global Benefits at CERN A minimum net entry-salary of 5929 Swiss Francs per month, increasing in line with your years of relevant experience. 30 days of paid leave per year plus 2 weeks annual closure. Coverage by CERN's comprehensive health insurance scheme (for yourself, your spouse and children), and membership of the CERN Pension Fund. Family, child and infant monthly allowances depending on your individual circumstances. A relocation package (installation grant, removal, travel expenses) depending on your individual circumstances. Possibility to extend your contract up to 8 years + eligibility for indefinite contract tenure. Be sure to meet the eligibility criteria You are a national of a CERN Member State or Associate Member State.
