  • define, develop, and maintain detailed concepts of operations for Galileo services with a focus on secure operations, ensuring alignment with overall mission objectives and security requirements.
  • lead the definition, analysis and consolidation of operational requirements for both system and segments, derived from mission/system requirements and operational concepts, encompassing SECOPS, PRS operations and SECMON operations.
  • support the implementation of overall security engineering for the Galileo system and segments, including security monitoring, to ensure adherence to the operational concept and consistency with input requirements.
  • support the implementation and technical consistency of operations' security requirements at the system level, ensuring alignment with overall system design and security objectives and proper definition and derivation of operational requirements resulting from security risk analysis.
  • act as a focal point for Galileo system security operational aspects within the Agency and with external partners, providing expertise and support.
  • support the System Integration Verification Team in the system qualification test campaign (e.g. SCTC, SFT) in contributing to the test procedures and linking them to the operational ones.
