Description
4S End-to-End System Architect in the Safety and Security from Space Programme Office in the Systems, Strategic Programme Lines and Technology Department, Directorate of Connectivity and Secure Communications.
The 4S (Space Systems for Safety and Security) Strategic Programme Line (SPL) is one of the three main strategic pillars of ESA’s telecommunications programme (ARTES). It focuses on next-generation SATCOM solutions that address governmental requirements and support infrastructure and/or applications critical to society, the economy and security. The programme prioritises security, resilience and sovereignty, which strongly influences how these SATCOM solutions are conceived, developed, validated and operated. Accordingly, the programme imposes stringent requirements on the supply chain and leverages cutting-edge technologies to meet high standards of security and resilience.
Rather than focusing on a single project in the capacity of a system engineer, you, as 4S End-to-End System Architect, will serve as the technical and system-level focal point for Connectivity and Secure Communications within the 4S domain. You will ensure the overall coherence and consistency of ESA’s activities in this area—both internally, by aligning them with the short-, mid-, and long-term objectives of 4S, and externally, by ensuring responsiveness to the needs expressed by the user communities who will ultimately rely on these solutions.
You will report to the 4S Strategic Programme Line Manager, who also serves as Head of the Safety and Security from Space Programme Office. You will work in close daily coordination with the 4S Implementation Manager, who is responsible for initiating and overseeing 4S projects and their execution by project and activity managers.
In the coming years, the programme will prioritise:

In the coming years, the programme will prioritise:
- space-based communication and surveillance solutions supporting air traffic management;
- space-based solutions for maritime traffic management, safety and security;
- enhanced protection of SATCOM assets, networks and services.
Your initial responsibilities as System Architect may focus on one or two of these strategic domains depending on your expertise, with a view to gradually expanding your scope to the full 4S portfolio.
Duties
Reporting to the Head of the Safety and Security from Space Programme Office, you will be the technical lead and solution reference for 4S matters. You will rely on and coordinate a network of experts, and your tasks and responsibilities will include:
- liaising with institutions, user communities, technical experts and industry to identify innovative secure SATCOM systems and technologies to respond to future user needs and emerging threats (including liaising with the European Commission in coordination with the IRIS² Programme Department);
- establishing accordingly a technical roadmap and action plans aiming to make the relevant end-to-end 4S solutions available in Europe, from an innovative and resilient European supply chain;
- leading the overall effort to ensure the consistency of the technologies to be invested in and of the new 4S activities at system and service levels, in coordination with relevant internal and external bodies;
- supporting the 4S Implementation Manager in defining activities to be procured;
- supporting the 4S procurement process, including through participation in tender evaluation boards;
- helping assess and then support the individual activities and projects proposed by industry in direct negotiation, with the aim of maximising the impact of their contribution (and related Member State investment) to the 4S strategy;
- supporting 4S-related project reviews, as needed;
- defining steps and processes related to capturing knowledge at the end of each activity, and feeding that knowledge back into the roadmap;
- promoting, from a technical point of view, the activities of the unit by participating in conferences and supporting marketing campaigns.
