Electromechanical Technician (EP-DT-DI-2019-76-LD)

  • Geneva, Switzerland
  • Contract

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


Are you a skilled electromechanical technician with experience in developing and/or maintaining control systems for large complex devices? Then seize the opportunity and join the Detector Technology Group operating at the heart of CERN’s Experimental Physics Department. Within our team, you will contribute to the design, development, construction and testing of challenging control systems for physics experiments, their powerful magnets and infrastructure. CERN, take part!

You will join:

  • The Experimental Physics (EP) Department carries out basic research in the field of experimental and particle physics in a stimulating scientific atmosphere, standing as an important reference for the physics community. It also contributes to the education and training of young scientists.
  • The Detector Technologies (DT) Group is in charge of the development, construction, operation and maintenance of many particle detectors and their technical infrastructure for the different experiments at CERN.
  • The Detector Interface Section provides solutions for infrastructure and detector control and safety systems, as well as data acquisition systems for physics experiments. The particularity of the Section is that it combines hardware, control systems, information and communication technologies expertise, thus being able to provide complete solutions, from the field to the user interfaces, including operations and support.


  • Operating, maintaining and upgrading the control and safety systems of the magnets of the Large Hadron Collider (LHC) experiments, as well as their ancillary systems (vacuum, heaters, batteries, etc.);
  • Taking part in a 24/7 on-call service for the experimental magnets and detector safety systems of the four large LHC experiments;
  • Developing, installing, operating and maintaining industrial data-acquisition, monitoring and control systems for experimental facilities;
  • Designing, constructing, testing and commissioning low voltage electrical circuits and networks;
  • Implementing safety interlock systems.


Technical certificate or general secondary education or equivalent relevant experience in the field of controls, automation, low voltage electrical distribution or a related field.


  • Extensive experience in operating and maintaining large electromechanical equipment and control systems;
  • Demonstrated experience in designing, implementing and commissioning low voltage electrical distribution systems;
  • Confirmed experience in design and assembly of control circuits and instrumentation interfaces;
  • Initial experience in PLC programming and development of user interfaces in SCADA frameworks.
  • Experience in participating to 24/7 on call services would be an advantage.

Technical competencies:

  • Installation, operation and maintenance of industrial data-acquisition, monitoring and control systems; this encompasses hardware, PLC programming and development/modification of simple SCADA systems.
  • Design and modelling of low-voltage electrical circuits and networks; this requires the knowledge of design tools such as CAD electrical design software.
  • Construction, test and installation of electromechanical equipment and systems: manufacturing basic mechanical pieces, assembling electro-mechanical sub-systems.
  • Operation and maintenance of large electromechanical equipment and systems, such as large normal- and super-conducting magnets.

Behavioural competencies:

  • Achieving results: delivering prompt and efficient service taking into account customer needs.
  • Demonstrating flexibility: adapting quickly and resourcefully to shifting priorities and requirements; demonstrating a willingness to accept changing circumstances; supporting initiatives for change.
  • Solving problems: producing workable and timely solutions that meet requirements.
  • Working in teams: building and maintaining constructive and effective work relationships.

Language skills:

  • Spoken and written English or French: basic knowledge of the other language or an undertaking to acquire it rapidly.
