ESTEC, Noordwijk, Netherlands  



Galileo Second Generation Ground Segment System Software Architect in the Ground Software Systems and Functional Verification Section, Software Systems Division, Systems Department, Directorate of Technology, Engineering and Quality.


If selected for this position, you will become part of the team responsible for modernising the existing Galileo Ground Segment software infrastructure and support the enhancement of navigation services through the integration of next-generation Galileo satellites. You will, in addition, support the procurement and development of the next-generation Ground Segment for Galileo. 


Using a state-of-the-art layered architecture, it is planned to operate software services from a common hardware platform. This Ground Segment infrastructure is a highly software-intensive system requiring modern software methodologies, tools and processes in view of the complexity of those services.


The Ground Segment deployment platform will use an Agile Release Train (ART) based on the Scaled Agile Framework (SAFe). 

Common services to be provided by the platform are:

  • IaaS (memory, compute and storage): 

                 data centre deployment; 
                 secure network services, including secure WAN; 
                 high-availability features, including business continuity;


  • PaaS: 

                resource abstraction layers (e.g. hyper-convergence, virtualisation, containerisation) ;
                scalability, platform management tooling, automated software deployment, software and hardware patching and accredited IT security and protection;


  • SaaS: 

                centralised security management (e.g. security monitoring, access control); 
                software service hosting, communication and interfacing (e.g. message queue, service mesh); 
                data.


For your first assignment, you will work as Integrated Support in the Galileo Second Generation Ground Segment Management Service within the Galileo Ground Segment Management Office in the Galileo Programme Department, Directorate of Navigation.


Training and familiarisation with the parent Department's mandate, processes and procedures will be provided at the start of this assignment.


Reporting to the Head of the Galileo Second Generation Ground Segment Management Service, you will act as business owner to oversee the continued specification, design and development of the platform, including suitable data management functions.

Your tasks and responsibilities will include:

  • leading the specification and procurement of the Second Generation deployment platform;
  • supporting management of the Second Generation Galileo Ground Segment unclassified and classified Technical Baseline (applicable requirements and standards);
  • supporting definition of the Second Generation Galileo Ground Segment Statement of Work (SoW) in accordance with the applicable ECSS standards and system design objectives;
  • providing support to the Second Generation Galileo System design activities as necessary to ensure consistency with the System Operational Concept;
  •  reporting regularly to the Head of the Galileo Second Generation Ground Segment Management Service;
  • supporting Ground Segment reviews in accordance with SoW milestones, applicable ECSS standards and the SAFe ART Program Increment Lifecycle.


As Integrated Support, you will also have the opportunity to work with a technical team of software specialists who support many ESA missions in the same technical domain. 


Finally, you will participate in periodic meetings with the parent Section, contributing to the transfer of technical knowledge and lessons learned across the Agency.
