Senior IVV Engineer 5GNTN

Senior IVV Engineer 5GNTN

Requisition Number: 19804 Contract Type: Permanent Location(s): Betzdorf, LU

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.

We are looking for a highly capable and experienced IVV Engineer to support the integration, verification, validation, and end-to-end testing of 5G Non-Terrestrial Network (NTN) solutions. This role is focused on validating the interoperability and performance of complex multi-domain systems spanning 5G Core, NTN-enabled Radio Access Network, satellite access segments, transport networks, virtualized infrastructure, and service platforms. The successful candidate will play a key role in system integration and end-to-end test activities across the 5G NTN ecosystem, ensuring that all network functions, interfaces, and operational workflows perform as expected under nominal and non-nominal conditions. The role includes support for test environment setup, platform integration, test execution, defect investigation, interface validation, and system-level acceptance.

The ideal candidate will have practical experience in telecom system integration and testing, with a strong understanding of 5G architecture, NTN concepts, multi-vendor interoperability, and end-to-end validation methodologies. Hands-on experience with virtualized platforms, Kubernetes-based deployments, interface testing, automation frameworks, CI/CD/CT environments, as well as 5G satellite communications and Flatsat Engineering Model environments, is highly desirable. The candidate will also contribute to test strategy development, regression validation, traceability, and continual improvement of IVV processes and tools.

Primary Responsibilities / Key Result Areas

• System Integration and IVV Activities
• End-to-End Testing and Validation
• System Commissioning and Test Environment Readiness
• Defect Analysis and Problem Resolution
• Automation and CI/CD/CT Contribution
• Configuration Management and Test Data Integrity
• Continual Improvement
• Technical Documentation
• Collaboration and Communication

The ideal candidate will demonstrate strong analytical and troubleshooting capability, with the ability to work across complex, distributed, and multi-vendor telecom systems. The role requires a structured approach to verification and validation, excellent attention to detail, and the ability to interpret requirements and translate them into effective test coverage. Strong written and verbal communication skills are essential, along with adaptability, collaboration, and a quality-focused mindset.

Qualifications Background and Experience Master's degree in Telecommunications, Engineering, Computer Science, or a related discipline. Minimum of 5 years of experience in telecom systems integration, testing, or IVV, ideally within 5G, mobile core, RAN, satellite communications, or cloud-native network environments. Experience in end-to-end testing and validation of complex telecom systems is strongly preferred. Exposure to 5G NTN, satellite communications, or non-terrestrial networking concepts would be a strong advantage.

The ideal candidate should have practical experience in system integration, verification, and end-to-end validation of telecom systems, with knowledge in the following areas:

• 5G NTN and RAN / Access Integration
• 5G Core and Network Function Integration
• End-to-End Testing and Interoperability
• Automation and CI/CD/CT
• Configuration and Environment Control
• Platform and Infrastructure
