Senior Architect, Cyber Security IRIS2

Senior Architect, Cyber Security IRIS2

The job responsibilities outlined in this document are not exhaustive and may evolve over time and be reviewed according to business needs.

PROGRAMME DESCRIPTION

IRIS2 is the new European Union securesatellite constellation. This project is the European Union's answer to the pressing challenges of tomorrow to provide secure connectivity services and enhanced communication capacities to the EU and its Member States. In addition, governmental users, private companies and European citizens while benefiting from ensuring high-speed internet broadband to cope with connectivity dead zones.

SES, together with other consortium partners and core members, was selected by the European Commission to build and operate the IRIS2 multi-orbit satellite constellation.

As the IRIS2 team enters the next project phases, there is a strong need of support for all the activities around service provisioning and products that the system can offer in the future.

ROLE DESCRIPTION SUMMARY

The Cyber Security Architect, IRIS² will be responsible for shaping and assuring the programme’s cybersecurity architecture, ensuring that security-by-design principles are embedded across the end-to-end system.

The successful candidate will work closely with Programme leadership, System Engineering, Space and Ground segment teams, Security workgroups, Services and Operations, consortium partners and external stakeholders to ensure that the IRIS² solution is secure, certifiable, operable and resilient.
