Arbetsbeskrivning

It's big, it's loud, it's cold, and it's one of the most challenging and exciting environments you can work in! Join the mechanical engineering team of the Cryogenic Group for a unique opportunity to work on machines that constitute nearly half of the world's large helium liquefiers. CERN, Take Part! At this world-leading research centre, helium needs to flow like water from a tap! To prepare for the next generation of particle colliders, such as the Future Circular Collider, CERN is launching an ambitious program for the development of Cryogenic Superconducting Radio Frequency Cavities and for the construction of dedicated cryogenic test facilities. The Cryogenics Group (CRG) in the Technology Department (TE) is responsible for the design, construction, commissioning, operation, and maintenance of cryogenic systems for accelerators and detectors, as well as for cryogenic test facilities. The group also supports low-temperature developments and tests at the Central Cryogenic Laboratory which provides expertise in cryogenic design and instrumentation. Your responsibilities Perform thermo-hydraulic and thermo-mechanical design and analysis of cryogenic equipment; Design cryogenic equipment and follow its construction in close collaboration with external suppliers and internal partners; Write technical specifications of cryogenic components and systems; Contribute to the management of projects and their quality control; Manage market surveys, material procurement and production follow-up; Supervise teams for the design, construction, assembly, installation, testing and commissioning of cryogenic equipment; Manage the associated technical documentation and Quality Assurance plan. Your profile Demonstrated experience with mechanical design of industrial equipment, preferably in the process or cryogenics field, including the preparation of technical specifications and support to procurement. Experience in contributing to the management of industrial projects, including planning, coordination of installation and commissioning activities, and interaction with suppliers and contractors. Experience in dealing with complex industrial processes, involving cryogenics, pressure equipment or vacuum technologies, would be an asset. Master's degree or PhD or equivalent relevant experience in the field of Mechanical Engineering or a related field. Your skills Design and analysis of mechanical structures, including thermo-mechanical analysis; Knowledge and application of numerical modelling in solid mechanics; Knowledge and application of thermodynamics and energetics, including heat transfer and fluid mechanics; Knowledge and application of manufacturing methods and work preparation: including definition, process, preparation, planning, drawing, and control; Project management, including knowledge of tools and methods; Is rigorous and produces quality results at first attempt; has a structured and organised approach towards work; is able to set priorities and plan tasks with results in mind; Shares knowledge and expertise freely and willingly with others; coaches others to ensure knowledge transfer; Identifies, defines and assesses problems, takes action to address them; Works well autonomously; takes on activities and tasks without prompting; takes initiative beyond regular tasks and makes things happen; Seeks to help other team members when own work is done; supports others; works well in groups and readily fits into a team; participates fully and takes an active role in team activities.
