Job of electromechanical technician at CERN

Company Description

At CERN, the European Organization for Nuclear Research, physicists and engineers probe the fundamental structure of the universe. Using the largest and most complex scientific instruments in the world, they study the basic constituents of matter – fundamental particles that are driven to collide at near the speed of light. The process gives physicists clues about how particles interact and provides insight into the fundamental laws of nature. Learn more at

job description


Come join an amazing team pushing the limits of superconducting accelerator magnets, to shape the future of CERN’s largest accelerator. CERN, participate!

The Magnets, Superconductors and Cryostats (MSC) group in the Technology Department (TE) has the mandate to design, build and measure the superconducting and normal conduction magnets for the CERN accelerator complex; integrating them into the CERN accelerator complex; design magnetic cryostats and perform magnet quality control. The group also provides accelerator operation support for magnets, magnet performance and devices.

The Cryostat and Machine Integration Section (CMI) is responsible for the design and construction of cryostats for accelerator superconducting devices, the integration of technical systems and installation in the machine. It is also in charge of the maintenance of the LHC SC magnet cryostats and the construction of spare parts. These activities take place in a dedicated facility on the CERN site, which is complemented by a storage building. The CMI Section is currently working on the design and construction of various equipment for the work packages of the HiLumi HL-LHC project (, and on the maintenance of the LHC SC magnetic cryostats.


As an Electromechanical Technician for the construction of cryo-assemblies in the CMI section, you will have to:

  • Build and assemble cryo-magnets and superconducting devices for test stations and particle accelerators.
  • Contribute to development programs and prototyping activities related to the engineering and construction of cryo-assemblies.
  • Manufacture mechanical and sheet metal parts, on plan and custom-made in some cases, with a view to their integration into cryo-magnets and superconducting devices.
  • Produce, install and commission custom tooling for the construction and assembly of cryo-magnets and superconducting devices.
  • Develop and produce instrumentation feed-through systems and end caps for cryo-magnets and superconducting devices.


Technical certificate or general secondary education or equivalent relevant experience in the field of mechanical engineering, electromechanical engineering or a related field.


  • Proven experience in electromechanics, manufacturing techniques and assembly of complex systems with tight tolerances.
  • Demonstrated experience in fabricating mechanical parts on conventional machine tools such as lathes and milling machines, as well as forming shells on rolling or bending machines and forming precision metal pipes.
  • Experience in the development of one-of-a-kind systems, which require the construction of mock-ups and special tooling.
  • Experience in manufacturing and assembling vacuum vessels and cryostats.
  • Experience in the development and manufacture of plugs for watertight penetrations in non-metallic materials would be an asset.

Technical skills :

  • Construction, testing and installation of electromechanical equipment and systems.
  • Manufacture of mechanical parts.
  • Good command of reading technical drawings, including ISO-GPS sizing.
  • Knowledge of sheet metal and pipe forming techniques.
  • Basic knowledge of computer-aided design software such as AutoCAD, Catia or SolidWorks.

Behavioral skills:

  • Demonstrate flexibility: demonstrate a willingness to accept changing circumstances; support change initiatives
  • Demonstrate responsibility: work conscientiously and reliably; keep his promises. Present information accurately and objectively.
  • Work as a team: understand when teamwork is necessary to achieve the best results; include others accordingly and share information. Cooperate constructively with others in pursuit of team goals; balance personal goals with team goals.
  • Building Relationships: Demonstrating courtesy and consideration in dealing with others. Show genuine interest in the concerns and perspectives of others. Show appreciation for the ideas and contributions of others and encourage others to express their views, even if they are controversial.

Language skills:

English or French spoken and written. Good knowledge of the other language or willingness to acquire it quickly.
