Electronics Technical Engineer (Design and Operation)

Do you have a Bachelor degree and a first experience in Electronics? Are you curious about understanding the interactions between electromagnetic fields and charged particle beams? Are you interested in participating in electronics design projects for RF systems of particle accelerators and in the operation and improvement of some of the largest accelerators in the world? You will take part in the development, testing and commissioning of new electronics, while also spending time on the operation of the existing systems. CERN, take part!

Job Reference: BE-RF-FB-2017-93-LD

Closing date:

Electronics Technical Engineer (Design and Operation) in the Beams Department (BE), Radio-Frequency Group (RF).


You will join:


  • The Beams Department (BE), which hosts the Groups responsible for beam generation, acceleration, diagnostics, controls and performance optimisation.

  • The Radio-Frequency (RF) Group (https://cern.ch/be-dep-rf) of the Beams (BE) department, responsible for the operation of all RF systems to accelerate and control the particle beams in all CERN synchrotrons and linear accelerators, including projects for future accelerators and upgrades to the existing installations.

  • The Feedback and Beam Control Section (FB) within the RF Group, responsible for the design and operation of all low power electronic systems needed for fast feedback control of the particle beams and to generate the drive signals to the RF power systems to accelerate and store the beams as well as to damp oscillations.



Two posts are open in the Group, one in the PS team, the other in the SPS Team.


As an Electronics Technical Engineer (Design and Operation), you will design electronic modules for the control and acceleration of proton and ion beams in the CERN accelerator complex. Some modules are custom-designed, others are from industrial suppliers, and your task would then be the design of the specific firmware and software. These modules contain high performance Field Programmable Gate Arrays (FPGA) or system on chip (SoC) for fast signal processing implementing field regulation algorithms, data logging and interfacing with the control system. The digital part is often preceded by analogue electronics converting RF signals in the 10 MHz - 1 GHz range to an intermediate frequency that can be sampled with today's ADC's.


Initially you will participate both in the RF electronics upgrade project and in the operation of the existing electronics, thereby gaining the necessary understanding of acceleration of charged particles. Most of CERN accelerators will be shut down in 2019 and 2020 when you will work full-time on the RF electronics upgrade project and which must be completed before the accelerators' restart in 2021.


For either post, you will in particular:


  • Participate in the operation and maintenance of existing RF electronics.
  • Develop firmware and embedded software to implement signal processing in FPGA.
  • Design mixed signal electronic modules containing a large digital processing part and RF electronics for legacy crate standards as well as most advanced standards.
  • Design script for hardware tests, set-up and commissioning.
  • Follow up production, integration with other accelerator components in close collaboration with colleagues.
  • Provide support for operation, including participation in an on call service during weekends, nights and public holidays.
  • Produce and manage the associated technical documentation.


Qualification required

Bachelor in the field of electronics, or equivalent.


*Please note that preference will be given to candidates with the above-mentioned qualifications: in principle consideration will not be given to applications from people with higher qualifications. 


Experience and competencies

The experience required for these posts is:


  • Experience in the design of digital electronics including firmware.
  • Experience with the use of modern tools for the design of firmware and embedded software.
  • Experience with the use of modern measurement instruments.
  • An interest in Beam physics and the interaction between accelerator RF systems and the particle beams.


The technical competencies required for this post are:


  • Design of electronics for digital control systems and loops.
  • Design of electronics based on field programmable logic-based devices (FPGA).
  • Analog circuit design, modelling and simulation.


The behavioural competencies required for this post are:


  • Working in teams: understanding when teamwork is required to achieve the best results; including others accordingly and sharing information.
  • Demonstrating accountability: working conscientiously and reliably; delivering on promises.
  • Demonstrating flexibility: readily absorbing new techniques and working practices; proposing new or improved ways of working.
  • Achieving results: having a structured and organised approach towards work; being able to set priorities and plan tasks with results in mind.


The language competencies required are:


  • Spoken and written English or French, with the ability to understand and speak the other language in routine situations or willingness to acquire this skill rapidly.
