Networks Architect; NTN & Global Space Connectivity

Future Networks Architect — Non-Terrestrial Networks (NTN) & Global Space Connectivity| UK

About the Opportunity
Join a pioneering deep-tech organization building the next generation of global connectivity across land, sea, air, and space. This team is redefining how satellite and cellular networks work together—enabling seamless, cloud-native orchestration of multi-orbit satellite systems and terrestrial mobile networks. Youll help shape the future of Direct-to-Cell, NTN, and the evolution toward 6G.

Were seeking a customer-facing Solutions Architect with deep expertise in SATCOM and 3

GPP mobile network architecture across RAN, Core, transport, and service orchestration. This role sits at the intersection of space systems, cellular networks, and cloud-native telecom platforms, owning end-to-end system architecture, technical trade-offs, and product evolution for advanced NTN and Direct-to-Cell solutions.

You’ll partner closely with customers, engineering, and product teams to define architectures, influence product direction, and help bring next-generation network capabilities to market.

System & Solution Architecture

• Design end-to-end architectures for NTN service chains (UE RAN Core Transport/SDN Service layer)
• Lead customer engagements for multi-orbit satellite systems integrated with 4G/5G (Rel-17+) and future 6G concepts
• Define system blueprints and interfaces across space, ground, and mobile network domains
• Translate customer requirements into technical architecture and execution plans
• Drive technology selection, trade studies, and technical proposal development

NTN & RAN Optimization

• Design and optimize RRM, scheduling, beam management, mobility, and interference coordination
• Address satellite-specific constraints such as Doppler, latency, beam hopping, and power limitations
• Architect advanced orchestration and spectrum-sharing capabilities for Direct-to-Cell networks
• Ensure alignment with regulatory and spectrum frameworks (ITU-R and regional bodies)

Standards & Ecosystem

• Apply and interpret relevant 3
  
  GPP specifications (RAN, SA, CT)
• Engage with industry forums and standards bodies (e.g., 3
  
  GPP, ETSI, GSMA, O-RAN, ESA)

Cloud, SDN & Automation

• Design orchestration and automation for RAN and Core functions, including FCAPS
• Define APIs and interfaces for automation and inter-domain coordination

Delivery & Stakeholder Leadership

• Lead technical engagements, proposals, and reviews across commercial and public-sector programs
• Act as a technical authority across engineering, product, partners, and customers

• Strong background in 4G/5G architecture across RAN and Core
• Proven SATCOM system architecture experience (space and ground segments)
• Deep knowledge of 3
  
  GPP architecture, protocols, and interfaces
• Hands-on understanding of PHY/MAC, scheduling, mobility, beamforming, and interference
• Experience producing architecture documentation and technical specifications
• Familiarity with networking protocols, RAN OAM, and control-plane concepts
• Knowledge of cloud-native networking, NFV, orchestration, and automation
• Excellent communication skills with experience engaging telecom, satellite, and defense stakeholders

• Direct experience with NTN or Direct-to-Cell systems and 3
  
  GPP Rel-17+ enhancements
• Familiarity with satellite constellations (LEO/MEO/GEO) and aerospace systems
• Knowledge of O-RAN (SMO, RIC, xApps/rApps) and GSMA APIs
• Experience with modeling, simulation, or digital-twin tools for network planning
• Scripting or software development experience
• Patents or publications in wireless, satellite, or mobile communications

Why This Role
Work on globally impactful technology, collaborate with world‑class engineers and customers, and help define how mobile connectivity extends beyond Earths surface.
