In particular, you will:

  • Design and develop features for the Rucio catalog component.
  • Improve the usability and performance of Rucio in the context of the scientific use-case of RI-SCALE.
  • Participate in DevOps tasks in operating a Rucio deployment for the project.
  • Participate in the evolution of the Rucio architecture at large.

Your profile

Skills

  • Excellent skills in the Python programming language.

    • a Master's degree with 2 to 6 years of post-graduation professional experience;
    • or a PhD with no more than 3 years of post-graduation professional experience.
  • You have never had a CERN fellow or graduate contract before.

Contract duration: 24 months, with a possible extension up to 36 months maximum.

Working hours: 40 hours per week

This position involves:

  • Stand-by duty, when required by the needs of the Organization.
  • Work during nights, Sundays and official holidays, when required by the needs of the Organization.

Job reference: EP-ADP-CO-2025-37-GRAP
