IRIS2 Ground Segment IT Infrastructure Engineer

Deadline to apply: 16/04/2026

We are looking for an IRIS² Ground Segment IT Infrastructure Engineer to complete our consultants’ Workforce Management Service to support ESA’s Directorate of Connectivity and Secure Communications (CSC) at ESA’s premises, mainly ESTEC (Noordwijk, NL).    

CSC supports innovation in satellite telecommunications and the development of advanced applications using space-based systems. Through research, development, and industrial partnerships, CSC contributes to strengthening the European and Canadian satellite communications sectors.  

 CSC also supports major public–private initiatives focused on the development of new satellite systems, validation of innovative services, and deployment of secure telecommunications capabilities. A growing portion of CSC activities involves third-party funded programmes, particularly within the Union Secure Connectivity Programme (IRIS²).  

 The CTAS will provide support to CSC with a multidisciplinary, onsite team of specialists who deliver technical, management, engineering, and security expertise across the IRIS² and EuroQCI programmes. The service supports CSC by reinforcing programme management, procurement, system design, verification, validation, security, and governance activities, enabling ESA to execute its entrusted responsibilities from the European Commission.  

 Through its work packages, CTAS personnel integrate directly into CSC project teams, ensuring day-to-day operational continuity, rigorous technical assessment, configuration and project control discipline, and support throughout all major ESA reviews and milestones. By deploying experts across spacecraft systems, ground segment development, telecommunications, quantum communications, security accreditation, and project governance, the service ensures CSC can efficiently manage complex, multi-partner programmes and maintain compliance with ESA, EC, and security requirements, ultimately strengthening Europe’s secure connectivity and communications capabilities.
