Senior Engineer, Network Orchestration Lead, IRIS2
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
Work requirements
The Network Orchestration Lead Engineer is responsible for leading the end-to-end orchestration architecture across MCC, SMO, SDN-C, GW Manager, OSS/BSS, RAN, Core Network, satellite payload, feeder links and inter-satellite links for a 5G-NTN multi-orbit satellite system. The role ensures that architecture, requirements, ICDs, RFPs, integration plans and delivery roadmaps are consistent across projects and aligned with the overall system objectives. The engineer coordinates cross-project activities, manages technical dependencies, supports vendor coordination, and provides technical governance for network automation and service orchestration activities.
General work requirements
Define and maintain the end-to-end network orchestration architecture across MCC, SMO, SDN-C, GW Manager, OSS/BSS, RAN, Core, satellite payload, feeder links and ISLs.
Synchronize cross-project technical activities, align roadmaps, define clear deliveries, manage dependencies, and ensure consistency between architecture baselines, requirements, ICDs, RFPs and integration plans.
Coordinate the definition of orchestration use cases, service/resource workflows, operational procedures, contingency handling, automation principles and cross-domain information flows.
Support the preparation and review of RFP/RFQ technical content, vendor clarifications, compliance matrices, technical evaluation reports, integration plans and risk mitigation actions.
Provide technical governance for network automation, service orchestration, multi-domain resource coordination, system engineering activities and cross-team delivery execution.
