Description

Job Description Are you a motivated computing graduate interested in global scientific infrastructure? Join CERN and contribute to the Computing Resource Information Catalogue (CRIC), a topology service describing computing and storage resources across the Worldwide LHC Computing Grid (WLCG), which connects over 150 computing centres in 40+ countries supporting particle physics research. CRIC is a key component of the WLCG ecosystem. Built as a modular Django web platform with a plugin-based architecture, it aggregates resource information from multiple sources and provides REST APIs and a web interface used in daily LHC computing operations. You will join the CERN IT Computing for Experiments group and help evolve CRIC by improving its maintainability, extensibility, and operational efficiency. This is a unique opportunity to work on distributed systems supporting one of the world's largest scientific computing infrastructures. Your responsibilities Contribute to the development and evolution of CRIC, a plugin-based Django platform while also strengthening automation, testing and CI/CD practices. Develop and operate data ingestion pipelines that collect and validate information from heterogeneous external systems. Contribute to deployment and operational workflows for CRIC instances currently managed through Puppet and CERN VM infrastructure. Your profile You enjoy building reliable, well-structured software and are curious about how large-scale distributed systems operate. You are comfortable working in Linux environments and collaborating through Git-based workflows. You have strong analytical skills and are able to evaluate trade-offs and propose pragmatic technical solutions. You communicate clearly and enjoy working in an international, multicultural environment. You are self-motivated, proactive and able to take ownership of technical tasks. Skills Strong Python programming and Django development experience. Proficiency in relational databases and data modelling. Good understanding of web technologies (HTML, CSS, JavaScript). Proficiency in automated testing and Git-based workflows in Linux environments. Familiarity with service configuration and deployment practices (e.g. configuration management, containerisation).
