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 motivated technician in the field of electronics and controls? If you are eager to acquire new skills and knowledge in a team of professionals who will train you in the field of controls for pulsed power systems applied to the largest particle physics laboratory in the world, this is an opportunity for you. CERN, take part!

You will join the Accelerator Systems Department (SY), which is responsible for the beam-related technical systems of the CERN accelerators. The SY teams design, build and operate equipment systems in all CERN accelerators, and are engaged in ambitious forward-looking R&D programmes.

The Accelerator Beam Transfer Group (ABT) is in charge of the design, development, construction, installation, exploitation, and maintenance of all the particle beam injection as well as the extraction equipment of the CERN’s accelerator complex.

You will be working in the Beam Transfer Electronics (BTE) Section specialised in the design and exploitation of controls electronics for all equipment under the responsibility of the ABT group and associated R&D activities.


As an electronics technician, you will take part in the operational support of existing hardware and study, design, develop and commission new hardware and supporting software for the control of beam transfer equipment across the whole CERN accelerator complex.
