Role overview
CERN operates the analysis ecosystem used daily by thousands of researchers: the SWAN interactive notebook service, the Rucio data management system, the REANA reproducible-workflow engine, the Zenodo open repository, and CVMFS for software distribution.
Building on these services, and as part of the ESCAPE Collaboration, CERN is developing the next generation of Virtual Research Environments (VRE): a modular, open-source analysis platform, deployed on CERN's Kubernetes infrastructure, that gives researchers a single entry point to data, software, and computing.
The VRE and its associated Open Science Competence Centre are being integrated into the CERN EOSC node, opening the platform to federated user communities across Europe.
