Secure Connectivity Ground Segment Service Engineer in the Secure Connectivity Ground Segment & 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”, also IRIS², 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.

Reporting to the Head of the Secure Connectivity Ground Segment & Operations Office, you will be responsible for supervising all ground segment service engineering tasks related to the effective design and development of the infrastructure providing services to the end users, operated by the IRIS² service management center, GOVSATCOM Hub and commercial operators.

Duties

Your tasks and responsibilities will include:

• supervising the end‑to‑end technical requirements lifecycle for the IRIS² service component of the ground segment —including OSS and BSS—covering functional, performance, operational, and security requirements, as well as decomposition to lower levels and the definition of associated interfaces;
• coordinating with domain teams, such as operations, security, and service management (ITIL), to ensure consistent requirements, aligned processes, and coherent operational workflows across the service infrastructure of the ground segment;
• preparing for, contributing to, and supporting project reviews at ground‑segment level, ensuring technical consistency, completeness of inputs, and alignment with applicable standards and milestone objectives;
• supervising the implementation of the service‑infrastructure activities, ensuring that delivered components meet defined requirements, interface specifications, and verification and validation plans;
• liaising with the system office to ensure correct implementation, integration, and validation of the interfaces between the system, the service component of the ground segment and the external interfaces (GOVSATCOM Hub, commercial operator), including support to interface control activities and cross‑segment coordination;
• supporting the alignment of OSS/BSS workflows with ITIL processes, including incident, problem, change, and configuration management, to ensure operational readiness and smooth service transition;
• monitoring relevant schedules and delivery progress, identifying risks and issues affecting the service infrastructure of the ground segment, conducting technical impact assessments, and proposing mitigation actions;
• monitoring and controlling changes and deviations/anomalies related to the service component of the ground‑segment, ensuring change requests are analysed for technical impact, documented properly, and implemented in a controlled and traceable manner;
• supporting integration activities involving 5G Core–related architectures, including the assessment of service‑based interfaces, exposure mechanisms, and operational workflows where applicable to the IRIS² service infrastructure;
• supporting the service and exploitation team at the European Commission managing the overall service lifecycle management (following ITIL).

Strong capability in supervising the full lifecycle of technical requirements for a service infrastructure, covering functional, performance, operational, and security aspects, as well as their decomposition into lower‑level requirements and associated interfaces.

Proven experience in coordinating cross‑domain technical activities, ensuring effective alignment with operations, security, system engineering and other relevant teams to maintain coherence across all requirements and interfaces.

Demonstrated experience in service management frameworks (eg. ITIL, TMF).

Expertise in supervising the implementation of service‑infrastructure activities, ensuring compliance with specifications, tracking integration status, and validating functional performance throughout the development lifecycle.

Solid experience in tracking, evaluating, and controlling changes, ensuring that all modifications are assessed for technical impact, properly documented, and implemented in a controlled and traceable manner.

Proven experience in the development and integration of large scale software systems.
