Job Details

Company Description

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. Find out more on

Job Description


Are you a Steel Structures Mechanical Engineer willing to represent CERN in the follow up of the production and assembly processes of the LBNF/DUNE cryostats?

You will be integrated in the LBNF/DUNE cryostats project structure, part of the Neutrino Platform CERN effort. Find more here:  

If you relish a challenge, join CERN`s Neutrino Platform and realize your potential. Take part!


As a Steel Structures Mechanical Engineer, you will:

  • Coordinate the Cryostat components production contracts execution, in particular: quality control, schedule follow-up, deliverables acceptance processes at contractors’ site and logistics. The production techniques involved in the manufacturing process are, cutting and welding steel plates and profiles and the assembly of mechanical structures. The dimensional acceptance will involve the application of conventional metrology techniques.
  • Coordinate the Cryostat assembly contracts execution, in particular: quality control, schedule follow-up, coordination with stakeholders at the erection site (SURF).You will be responsible of the follow-up of the work program of the contractor in charge of the assembly of the Cryostats, accepting and verifying the advancement of the works according to the technical specifications and the corresponding contractual conditions. The dimensional acceptance will involve the application of conventional metrology techniques. You will be responsible of the in-situ coordination of CERN activities contractors in the framework of the overall activities at SURF during the Cryostats assembly contract execution.
