As EO Security Applications Engineer, you will report to the Head of the Enterprise Section in the Climate Action, Sustainability and Science Department within the Directorate of Earth Observation Programmes.
The European Resilience from Space (ERS) programme was agreed at the ESA Council at ministerial level in November 2025. This programme will initiate the rapid development and consolidation of European EO capabilities to address gaps and constraints in the availability of and access to adequate EO-derived information for security stakeholders. It will support the preparation a pan-European system of satellites and groups of Member States developing solutions to support cooperative threat mitigation. In addition, the programme contains an element to support Member States in developing “Security Resilience Nodes” enabling enhanced access to state-of-the-art space infrastructure and customised space applications for national stakeholders. These Nodes will build on developments in complementary ESA programmes (in particular Future EO) and will generate requirements for additional EO applications and services to be developed under these programmes. In addition, Nodes will leverage developments under Future EO that address enhanced coordination between private satellite operators, national mission operators and advanced applications and analysis capabilities to better address individual Member State interests.
You will be responsible for ensuring relevant lower TRL EO application and service developments are effectively integrated into the appropriate Nodes, supporting relevant capability developments within particular Nodes, ensuring priority requirements from individual Nodes are translated into R&D activities within Future EO and liaising with institutional and industrial stakeholders to ensure emerging requirements are efficiently and credibly addressed.
