PROGRAMME DESCRIPTION IRIS² is the new European Union secure satellite communications 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 as well as to governmental users, private companies and European citizens while ensuring high-speed internet broadband to cope with connectivity dead zones. SES – together with other consortium partners and core members – was selected by European Commission to build and to operate the IRIS² multi-orbit satellite constellation. The IRIS² team enters the next project phase and there is a strong need for support for all the activities around service provisioning and products that the system can offer in the future. ROLE DESCRIPTION SUMMARY The IVV & SW O-RAN Integration Engineer (Feeder Link) is responsible for defining, integrating, validating, and verifying software and radio protocol functions supporting 5G NTN feeder link integration. The role focuses on O-RAN based integration activities, 5G radio protocol layers, end-to-end test strategy, and software validation across satellite, feeder link, ground gateway, and RAN lab environments.
