Job description

Join a great team pushing the limits of superconducting accelerator magnets, to shape the future of CERN largest accelerator. Take part!

You will join:

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, to integrate them in the CERN accelerator complex, to design and procure the magnet cryostats and to perform the magnet quality control. The group also provides support to operation of the accelerators for magnets, magnet performance, devices (current leads).

The LMF section manages the Large superconducting Magnets Facility. Its main responsibility is to provide a CERN-wide support for the engineering, manufacturing and maintenance of superconducting accelerator magnets, in particular for the LHC and its upgrades.

Functions:

As a hands-on mechanical technician in the LMF section, you will take an active part in the work related to cold masses for superconducting magnets.

In particular, you will:

  • Perform assembly, repair, disassembly and maintenance work on cold masses, including fitting, shaping of components and machining of parts (on the cold mass with dedicated tools or offline, on conventional machine tools) according to CERN safety rules.
  • Execute laser tracker measurements on cold masses as needed to machine, align and perform fiducialization of parts or assemblies.
  • Carry out acceptance tests on parts, such as standard mechanical inspections and preparation for vacuum testing.
  • Place orders with the CERN central warehouse, CERN preferred suppliers or other external contractors for consumables and other material / tooling related to cold masses.
  • Contribute to the development and construction of tooling, jigs and mock-ups related to cold masses and their interconnections.
  • Participate to activities in the LHC accelerator, such as the preparation of consolidation campaigns in the tunnel, or the removal and installation of superconducting magnets.

Qualifications:

Higher technical diploma or equivalent relevant experience in the field of mechanics, machining or a related field.

Experience:

  • Previous experience in several of the following fields: machining of metalling components (traditional, non-CNC milling and turning); mechanical assembly and fitting; manufacture or maintenance of mechanical or electromechanical systems.
  • Proven experience in reading technical drawings, including ISO-GPS dimensioning.
  • Experience with mechanical metrology in 3D, including coordinate transformations, would be an advantage.
  • Experience with superconducting magnets, cold masses, vacuum or cryogenic equipment would be an advantage.

Technical competencies:

  • Assembly of mechanical structures and equipment.
  • Knowledge and application of manufacturing methods and work preparation.
  • Manufacturing of mechanical parts: with traditional (non-CNC) machine-tools and custom-made tools.
  • Knowledge and application of conventional dimensional metrology.

Behavioural competencies:

  • Working in teams: cooperating constructively with others in the pursuit of team goals; balancing personal goals with team goals.
  • Demonstrating flexibility: adapting quickly and resourcefully to shifting priorities and requirements.
  • Demonstrating accountability: taking responsibility for own actions and decisions.
  • Achieving results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.

Language skills:

Spoken and written English or French: ability to understand and speak the other language or the undertaking to acquire it rapidly.

Eligibility and closing date:

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success. We welcome applications from all Member States and Associate Member States.

This vacancy will be filled as soon as possible, and applications should normally reach us no later than 18.07.2021 at 12:00 CET (midday).

Employment Conditions:

Contract type: Limited duration contract (5 years). Subject to certain conditions, holders of limited-duration contracts may apply for an indefinite position.

These functions require:

  • Work in Radiation Areas.
  • Interventions in underground installations.
  • A valid driving licence is required.
  • Work during nights, Sundays and official holidays, when required by the needs of the Organization.
  • Shift work, when required by the needs of the Organization.
  • Stand-by duty, when required by the needs of the Organization.

Job grade: 3-4

Job reference: TE-MSC-LMF-2021-67-LD

Hvem er CERN?

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.
