This salary is estimated based on similar roles. The actual salary may vary.
Introduction
You will play a major role in the evolution of non-relational data stores and big data platforms, based on technologies such as Hadoop and Spark. You will apply your software engineering expertise to large and long-lived data platforms, high-throughput ingestion pipelines, performance-critical access patterns, and demanding reliability requirements. Your work will directly support the operation, monitoring, and analysis of particle accelerator systems through the management of multi-petabyte datasets accumulated over many years.
Functions
• Drive the evolution of the CERN Accelerator Archival system (NXCALS). 
• Design and develop the core components of the system, including ingestion pipelines (ETL), metadata services, data compaction mechanisms, data extraction algorithms, and APIs. 
• Collaborate with different user communities to define and promote best practices for using NXCALS in the development of control applications for the CERN Control Centre. 
• Work closely with the CERN IT department to select and validate evolution of the underlying storage technologies (e.g. HDFS, ClickHouse). 
• Contribute to the operation, maintenance, and user support of the system. 
• Keep watch on relevant big-data technologies and assess their applicability to NXCALS. 
• Mentor and technically support junior software engineers contributing to these activities. 
• Contribute to the development of other Controls data engineering platforms according to overall priorities.

About CERN
CERN, the European Organization for Nuclear Research, is a premier international research institution dedicated to fundamental physics. Established in 1954 near Geneva, Switzerland, CERN brings together scientists from around the world to explore the fundamental nature of the universe. The organization operates as a collaborative hub for cutting-edge research, focusing on particle physics and the development of advanced technologies to support scientific discovery. Its mission is to push the boundaries of human knowledge through large-scale, collaborative experiments. CERN’s primary activities include operating the Large Hadron Collider (LHC), the world’s largest and most powerful particle accelerator, and conducting experiments to investigate the fundamental constituents of matter and the forces that govern them. The organization also develops and shares innovative technologies, such as the Worldwide LHC Computing Grid, which processes and stores vast amounts of experimental data. CERN’s work primarily serves the global scientific community, including physicists, engineers, and researchers, who collaborate on groundbreaking projects aimed at advancing our understanding of the universe. Notable achievements include the discovery of the Higgs boson in 2012, a milestone in particle physics, and the development of the World Wide Web, originally created to facilitate information sharing among researchers. CERN holds a unique position as a leader in both scientific research and technological innovation, fostering international cooperation and driving progress in fundamental science. Its open-access approach to data and technology ensures that discoveries benefit the broader scientific community and society at large.
