Description

ESA maintains a world-leading Science Programme with missions in heliophysics, planetary science, astrophysics and fundamental physics. Its mission is to "empower Europe to lead space science". The Department of Science Operations hosts the scientists and engineers that oversee the space missions, from study to end of operations. It defines and develops the science operation systems for the missions and operates the missions in space, as well as archiving and curating their data during operations and beyond. Its main objective is to maximise the scientific output of ESA's space science missions for the benefit of humankind.

You will join the Data Science Section as Science Operations System Engineer for Cloud Platform to support the development and extension to cloud of the ESA Datalabs ) science platform, with primary application to the Euclid Data Space. The Data Science Section is a cross-disciplinary team working closely with the ESA science missions: primarily Euclid, Gaia, XMM-Newton and JWST. Aside from experts in astronomy, computer science and software systems engineering, the Section works with young professionals, researchers and students at universities. Through its diverse setup, the Section handles tasks ranging from technical infrastructure and scientific activities to building (international) community efforts around data science and machine learning.

As Science Operations System Engineer for Cloud Platform development, you will be tasked with supporting the extension of the existing ESA Datalabs platform into a hybrid multi-cloud setup providing access to petabytes of data to scientists worldwide, leveraging the capabilities of both European cloud providers and partnering academic institutions. As the platform serves as a foundation for machine learning use cases, in particular for scientific machine learning projects aimed at increasing return on science, your role will define and provide the respective components of the platform for MLOps, pipeline orchestration and load balancing, for example, jointly with suppliers from industry.

Duties

Within the Data Science Section, you will be responsible for:

• supporting the definition and implementation of the architecture for a hybrid-cloud science platform (expanding ESA Datalabs - );
• defining and formalising the ESA Datalabs system architecture down to the level of individual functionalities, including ensuring that the process and tools exist to capture, de-conflict and implement all associated requirements;
• supporting the design, implementation and testing of platform modules based on corresponding development plans;
• promoting multiple types of use cases on the platform, such as data science, citizen science and science operations;
• contributing to the Department's data science strategy in close collaboration with the ESAC Science Data Centre and the science missions;
• acting as Technical Officer for industrial services and external contracts supporting the activities of the Section;
• Supporting the Head of the Data Science Section on any relevant Section matters;
• supporting the management of interfaces to other ESA directorates and to partnering space agencies, including platform federation activities.
