Description

Secure Connectivity 5G NTN End-to-End System and Validation Lead Engineer in the System Architecture Section, Secure Connectivity System Office, Secure Connectivity Programme Department, Directorate for Resilience, Navigation and Connectivity.

The ESA Programme Related to EU Secure Connectivity, 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. This includes the follow-up of the system design and development for IRIS2.

The System Architecture Section in the Secure Connectivity System Office is responsible for all systems engineering tasks to support the effective design and development of the overall Secure Connectivity system of systems. This includes the follow-up of the 5G implementation in the IRIS2 system.

Reporting to the Head of the Secure Connectivity System Architecture Section, you will be responsible for the implementation and validation in IRIS2 of 5G NTN (non-terrestrial networks), considered as an end-to-end product covering the space segment, ground segment and user terminal.

Duties

Your tasks and responsibilities will include:

• following the implementation of 5G within the end-to-end system architecture, system behaviour, concept of operations, system scenarios and use cases;
• establishing and maintaining the IRIS2 5G roadmap, describing the incremental implementation of the system capabilities through successive 3GPP releases;
• ensuring technical end-to-end consistency of the satellite access network, notably considering the resource management and 5G end-to-end implementation;
• ensuring the derivation and traceability of the 5G system and segment requirements including functional, performance, operational, service and security requirements;
• proposing corrective measures to respond to deviations from mission requirements established at programme level;
• defining, specifying and maintaining end-to-end performance requirements, KPIs and associated verification and validation strategies for 5G NTN services across the space, ground and user segments;
• leading and coordinating end-to-end performance validation activities, including system-level simulations, testbeds, ground testing and in-orbit validation campaigns;
• monitoring and assessing system-level performance against defined budgets (capacity, latency, availability, reliability, QoS/QoE), identifying deviations and ensuring consistency with mission and service requirements;
• supporting the definition and execution of performance test plans, validation scenarios and measurement methodologies in coordination with industrial partners and internal ESA stakeholders;
• ensuring traceability between performance requirements, system architecture design choices and validation results;
• following the user terminal development to ensure the correct end-to-end implementation of the 5G air interface;
• liaising with the Ground Segment Office, the Security Office, the Space Segment Office, the PA and Safety Office, and the relevant industrial actors in order to ensure a proper understanding and implementation of the 5G NTN;
• supporting the preparation and participation of reviews relating to Secure Connectivity at system and segment level;
• supporting all engineering and R&D activities directly relating to the development and implementation of the system;
• supporting the preparation of future generations of the Secure Connectivity system of systems;
• monitoring relevant schedules in a proactive manner, identifying risk and problem areas in the System Office, providing assessments and proposing mitigation actions from industry and on the ESA side;
• providing regular reporting to project management on all aspects of your competence;
• supporting technical interaction with national delegations, the IRIS2 programme (the European Commission), the European Union Agency for the Space Programme and the different standardisation bodies such as 3GPP;
• taking on responsibility for programmatic aspects if delegated from project management.
