Digital Electronics Engineer

Context & Job description

The Radio Frequency Group  (RF) develops, operates and maintains the instrumentation and equipment used to increase and maintain the energy of the electrons circulating in the accelerator complex of the ESRF. The Electronics Unit of the Detector & Electronics Group provides support and development capabilities in the area of electronics required for detectors, beamline instrumentation and accelerator control, data acquisition and alike.

The RF Group and the Electronics Unit have initiated the development of a digital low level RF system (DLLRF), for the implementation of a fast RF feedback system. It will allow controlling the future double frequency RF system comprising the existing accelerating cavities and new harmonic cavities that will boost the performance of the ESRF storage ring.

Your missions will be to:

  • Contribute as main FPGA and digital electronics developer to the construction and validation of the new  DLLRF system.
  • Interact with the staff of the RF Group and the Electronics Unit to build on the expertise, technologies and methodology in use at the ESRF.

Your main tasks:  

  • Complete and validate the architectural choices of the new digital low level RF system.
  • Implementation of the application framework (FPGA firmware) including the optical communication links between the various modules that will configure the fast digital RF feedback system.
  • Proceed to the study, comparison, practical implementation and exercising of the digital regulation algorithms that will be considered and evaluated for the project.
  • Complete the implementation, test, deployment and documentation of the final DDLRF system in the accelerator complex.

Expected profile

  • A minimum of 5 years of experience in digital electronics design and FPGA programming
  • In-depth knowledge of digital electronics design, FPGA programming and related tools
  • Strong skills and background in application of computing tools, including technical programming for electronics and scientific instrumentation
  • Some experience in high-speed data processing and data transmission
  • Some knowledge and familiarity with microwave equipment will be an asset
  • Good interpersonal skills are essential to integrate into a multidisciplinary and international team
  • Good aptitude for teamwork
  • Ability to multitask and prioritize commitments efficiently according to deadlines and milestones
  • Good project and time management skills are an asset
  • Initiative, autonomy, team spirit, methodical approach to work, well-organised
  • Proficiency in English (working language at the ESRF)

Working conditions

Temporary contract, up to 36 months.

We offer a comprehensive benefits package designed to support your quality of life and your installation in the Grenoble area when relocation is needed.

The monthly salary may be complemented by additional allowances upon eligibility (expatriation allowance, etc.).
