Our ultimate goal is a seamless, reproducible analysis environment where researchers can discover and access data, run interactive and batch analyses across heterogeneous resources, and publish their results within one open ecosystem. This is a unique opportunity to work at the core of CERN’s analysis services and shape a platform adopted by research infrastructures well beyond CERN.
