Description
Secure Connectivity Low LEO Lead Ground Segment Engineer in the Secure Connectivity Ground Segment and Operations Office (CSC-IG) within the Secure Connectivity Programme Department (CSC-I) in the Directorate of Connectivity and Secure Communications.

The ESA programme related to EU Secure Connectivity, hereinafter referred to as “Secure Connectivity”, is intended to support the effective development and validation of the EU Secure Connectivity governmental infrastructure and the services provided by it, as well as the validation and demonstration of services based on the commercial infrastructure developed by the contractor(s) delivering the EU Secure Connectivity governmental infrastructure.

The Low LEO Layer is intended to develop and test pre-operational concepts. It will include the design, development and testing of Low LEO, focusing on hard governmental and light governmental services improvements. These activities will be defined in coordination with the European Commission, which will ensure full compliance with the Secure Connectivity Concession Agreement and, where applicable, the governance of the relevant EU space component.

Reporting to the Head of the Secure Connectivity Ground Segment and Operations Office and to the Low LEO Implementation Manager, you will be responsible for leading the Low LEO Integrated Project Team in Spain, with accountability for delivering the work packages associated with the consolidation and implementation phases of the ESA Low LEO programme in the areas of ground segment, operations, launch, LEOP, IOT and the roadmap for later integration into EU IRIS2.

Duties
Your tasks and responsibilities will include:

• leading and coordinating the Low LEO Integrated Project Team (IPT) in Spain, ensuring coherent execution of activities associated with the Low LEO programme component within the areas of responsibility assigned to the IPT;
• coordinating closely with the Low LEO Team at ESTEC to ensure full technical and programmatic alignment across all related activities, schedules and implementation priorities, and contributing to reporting to ESA management as required;
• managing the consolidation and implementation activities relating to the Low LEO IPT in Spain, ensuring alignment with programme objectives, schedules, operational constraints and pre-operational service needs;
• coordinating industrial activities and interfaces with consortiums, institutional partners and operational stakeholders to ensure effective delivery of the areas of responsibility assigned to the Low LEO IPT in Spain;
• managing activities relating to the ground segment, operations preparation and operational concepts, ensuring end-to-end consistency, service readiness and operational feasibility across ESA Low LEO activities, while identifying and coordinating synergies with the EU Low LEO-related activities;
• coordinating the preparation and execution of launch, LEOP and IOT activities, ensuring readiness, interoperability and smooth transition towards operational validation across ESA Low LEO activities, while identifying and coordinating synergies with the EU Low LEO-related activities;
• ensuring technical and operational compatibility of the Low LEO component with the future EU IRIS² baseline and associated secure connectivity services;
• supporting the definition and execution of the roadmap for the progressive integration of Low LEO capabilities into the wider EU IRIS² ecosystem;
• providing support to system architecture and platform consolidation activities, including identification of synergies and alignment opportunities with EU Low LEO activities;
• monitoring programme risks, technical dependencies, schedules and implementation progress, proposing and coordinating mitigation actions where required;
• ensuring that operational concepts, validation strategies and service demonstrations are technically mature, operationally credible and aligned with programme timelines and objectives;
• close coordination with other project disciplines, including the System Office, the Space Segment Office, the Security Office and the Product Assurance and Safety Team, as well as with the Directorate of Controlling, Finance and Operational Procurement;
• providing regular reporting, strategic recommendations and implementation status updates to the Head of the Secure Connectivity Ground Segment and Operations Office.
