Solutions Architect, 5G NTN

Role Overview:

We are looking for a Solution Architect (SA) with deep expertise in end-to-end SATCOM and 3GPP mobile network architecture, spanning RAN, Core, transport, and service orchestration, with a strong focus on 4G/5G Non-Terrestrial Networks (NTN) and Direct-to-Cell and their evolution toward 6G, to join our growing NTN/DTC team within the Spacetime division.

The role sits at the intersection of space systems, cellular networks, and cloud-native telecom orchestration platforms, owning architectural definition, product evolution and definition, end-to-end system architecture technical trade-offs, and system-level optimization across the full stack, to be implemented in Aalyria’s Spacetime platform.

The role also involves a heavy customer-facing component, with the candidate expected to be comfortable interfacing with customer stakeholders at all levels and be able to lead technical discussions with customers or prospective customers, with an eye towards business development.

Key Responsibilities:

• SATCOM and NTN RAN optimization, O-RAN SMO/RIC, SON & Radio Resource Management (RRM)
• • Design and optimize radio resource management (RRM), scheduling, beam management, mobility, and interference coordination mechanisms
  • Support development of customer resource management solutions and Spacetime algorithms to be implemented by Aalyria Spacetime software engineering team
  • Address satellite/NTN-specific constraints (Doppler, delay, ephemeris, beam hopping, power limits, feeder link constraints)
  • Drive the design and support the implementation in Spac
