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 http://home.cern.

Job Description

Introduction

Come and join a great team pushing the limits of superconducting accelerator magnets, to shape the future of CERN’s largest accelerator. CERN, take part!

The Magnets, Superconductors and Cryostats (MSC) group of the Technology Department (TE), has the mandate to design, construct, and measure the superconducting and normal conducting magnets for the CERN accelerator complex; integrate them in the CERN accelerator complex; design the magnet cryostats and perform the magnet quality control. The group also provides support to the operation of the accelerators 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, integration of technical systems, and installation in the machine. It is also in charge of the maintenance of the LHC SC magnet cryostats and construction of spares. 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 (https://hilumilhc.web.cern.ch), and on the maintenance of LHC SC magnet cryostats.

Functions

As Mechanical Technician for the construction of cryo-assemblies in the CMI section, you will:

  • Construct and assemble cryo-magnets and superconducting devices for particle accelerators and test stations;
  • Contribute to development programs and prototyping activities in relation with the engineering and construction of cryo-assemblies;
  • Manufacture mechanical and sheet metal parts, as per drawings and bespoke in some cases, in view of their integration in cryo-magnets and superconducting devices;
  • Produce, install, and commission bespoke tooling for the construction and assembly of cryo-magnets and superconducting devices;
  • Oversee welding activities carried out in the section and, according to needs, execute welding operations on stainless steel piping of a few millimeters thickness.

Qualifications

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

Experience:

  • Proven experience in mechanics, manufacturing techniques, and assembly of complex systems to tight tolerances;
  • Demonstrated experience in conventional mechanical machining (turning, milling) of parts, as well as shells forming (rolling, folding machines) or forming of metal precision pipes;
  • Experience in the development of first-of-a-kind systems, which require the construction of mock-ups and dedicated tooling;
  • Experience in the fabrication and assembly of vacuum vessels and cryostats would be an asset;
  • Experience in welding technology, particularly TIG welding applied on stainless steel piping, would be a plus;
  • Basic experience with Computer Aided Design software such as AutoCAD, Catia or SolidWorks, would be an advantage.

Technical competencies:

  • Construction, test and installation of electromechanical equipment and systems;
  • Manufacturing of mechanical parts: and machining (conventional lathe and milling machine);
  • Reading of 2D drawings and 3D models, including ISO-GPS dimensioning and cabling diagrams;
  • Knowledge of sheet metal and pipe forming techniques.

Behavioural competencies:

Demonstrating Flexibility:

  • Demonstrating a willingness to accept changing circumstances; supporting initiatives for change.

Demonstrating Accountability:

  • Working conscientiously and reliably; delivering on promises;
  • Presenting information accurately and objectively.

Working in Teams:

  • Understanding when teamwork is required to achieve the best results; including others accordingly and sharing information;
  • Cooperating constructively with others in the pursuit of team goals; balancing personal goals with team goals.

Learning and Sharing Knowledge:

  • Keeping up-to-date with developments in own field of expertise and readily absorbing new information.

Language skills:

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

Company

CERN profileAt CERN, physicists and engineers use the world’s largest and most complex scientific instruments to study the basic constituents of matter – the fundamental particles – to probe the underlying structure of the universe.

Working at CERN
CERN is a truly unique organization. A genuine collaboration between countries, universities and scientists, driven not by profit margins, but by a commitment to create and share knowledge. At CERN, students, recent graduates and experienced professionals work together to push for immense scientific discoveries, answering some of life’s most complex questions and advancing the boundaries of human knowledge.

People are free to work creatively and to trust in, and rely on, their colleagues across the organization. History is being made at CERN – and the excitement is tangible, inspiring, overwhelming at times. It is the only place in the world that you can do this work in this way.

Why work for us
Today, CERN employs more than 2500 people, and if you visit us you will find more than 2500 different reasons why CERN is such a great place to work. Six key reasons that we believe will make you love working here are: challenge; purpose; imagination; integrity; collaboration; and quality of life.

Student and graduate schemes
CERN technical and administrative internships and graduate schemes offer international students and recent graduates the opportunity to work with world-class scientists and engineers on cutting-edge research in particle physics, computational science, life sciences, engineering, international relations, and more. Whichever route you take, it will be an extraordinary experience.

What we are looking for
To conduct experiments of this scale and importance, CERN needs people from various career levels and with a wide range of abilities, skills and competencies. We have job opportunities for students, graduates and experienced professionals, from apprenticeships to PhDs (and beyond). Whatever your background, field of interest or diploma level, CERN could be the place for you.
