Job Summary
In this role, you will act as the technical authority for 5G NTN architecture, define system architectures, drive RAN requirements, and ensure multi-vendor integration in complex projects.
Job Technologies
Your role in the team
- You will act as the end-to-end technical authority for 5G & 3GPP NR NTN architecture and system integration, spanning RAN, payload, SMO/O-RAN, and core network domains.
- Your primary focus is to define the system architecture, drive RAN requirements, and ensure successful multi-vendor integration and validation.
- You will lead critical technical decisions, and align engineering teams across domains.
- Within your first year, you will enable a fully integrated NTN system, with clear RAN requirements, validated interfaces, and a robust verification strategy supporting demo and flight readiness.
- As a 5G Architect, 3GPP NR NTN, meoSphere, you will be responsible to: Define and assess 5G RAN and 5G-NTN solution architectures, including NG-RAN functional split, protocol stack, radio interface behavior, and integration with terrestrial and non-terrestrial network environments.
- Define and drive the 3GPP NR NTN system and RAN architecture, including key trade-offs across payload, RAN, and core.
- Perform and document trade-off studies covering RAN architecture, RF performance, beamforming, beam hopping, beam sweeping, coverage enhancement, mobility, and implementation complexity.
- Provide architecture guidance on 5G RAN protocol stack design and integration, including RRC, SDAP, PDCP, RLC, MAC, PHY interactions and NG-RAN architecture interfaces.
- Act as the technical authority for the E2E 5G NTN architecture, aligned with 3GPP Rel-17/18/19 and future evolution.
- Drive integration of NTN RAN with 5G Core, with particular focus on distributed UPF and core architectures.
- Lead SMO / O-RAN architecture and development direction, including SMO concepts and real-time RIC integration.
- Act as the primary technical interface across RAN, payload, core, and orchestration teams.
- Coordinate all RAN-related activities across internal teams and external partners.
- Ensure multi-vendor alignment on requirements, interfaces, and integration priorities.
- Führen Sie End-to-End-Systemintegration, Verifizierung und Leistungsoptimierung durch.
- Support technology roadmap, system evolution, and standardization activities.
- Provide technical guidance and mentoring to senior engineers across domains.

Our expectations of you
Qualifications
- Expert knowledge of 3GPP 5G RAN and 5G-NTN standards, including RAN2 radio layer 2 protocols, RAN3 NG-RAN architecture, and RAN4 RF/RRM performance aspects.
- Starkes Wissen über 5G-NTN-Funktionen, einschließlich Beamforming-Techniken, Beam Hopping, Beam Sweeping, Random Access-Verfahren in NTN und bedingtes Handover in NTN.
- Solid knowledge of 5G Core architecture, including UPF and distributed deployments.
- Starkes Verständnis der NTN-Beschränkungen und Satellitenkommunikationssysteme.
- Knowledge of O-RAN architecture, SMO, and RIC frameworks is nice to have.
- Background in PHY, link-level performance, or system simulation is nice to have.
- Participation in 3GPP standardization or advanced research programs is nice to have.
- System owner mindset - drives coherence across domains and vendors.
- Pragmatic rigor - defines clear requirements and verification without blocking delivery.
- Hands-on architect - capable of diving into technical issues when needed.
- Low ego, high standards - builds alignment across strong technical stakeholders.
- The candidate must be eligible for a "SECRET" security clearance, in accordance with the national regulations as well as EU/ESA/NATO equivalents.
- Willing to work at least 60% onsite from office.
- Reisen Sie bei Bedarf zu Projektumsetzungszwecken.
Experience
- 10+ years in wireless systems, RAN, NTN, or satellite communications.
- Experience with RAN/RF performance modelling, coverage analysis, link budget interpretation, mobility studies, and vendor-provided simulation or planning outputs.
- Hands-on experience with multi-vendor environments, bring-up, and vendor coordination.
- Experience with beam hopping, beam management, or payload optimization is nice to have.
