Solution Architect

Overview

We are supporting a cutting-edge technology company at the forefront of satellite communications and temporospatial networking. The company is revolutionizing the orchestration and management of planetary mesh networks across land, sea, air, and space.

We are seeking a Solution Architect with deep expertise in end-to-end SATCOM and 3

GPP mobile network architecture (RAN, Core, Transport, and Service Orchestration), with a strong focus on 4G/5G Non-Terrestrial Networks (NTN), Direct-to-Cell systems, and the evolution toward 6G.

This role sits at the intersection of space systems, cellular networks, and cloud-native telecom orchestration
, owning architectural definition, product evolution, system-level optimization, and driving customer-facing technical engagements.

• Lead solution architecture for multi-orbit satellite systems integrated with 4G/5G NTN and future 6G concepts.
• Define end-to-end system architectures (UE → RAN → Core → Transport/SDN → Service layer).
• Own architectural blueprints, interfaces, and decomposition across space, ground, and mobile network domains.
• Drive technical proposals, customer engagement, and requirements collection.
• Optimize SATCOM and NTN RAN, including radio resource management (beam management, mobility, scheduling, interference coordination).
• Ensure solutions meet regulatory and spectrum requirements (ITU-R, regional regulators).
• Contribute to standards bodies and industry forums (3
  
  GPP, ETSI, GSMA, O-RAN, ESA NTN Forum, etc.).
• Define orchestration and automation strategies for cloud‑native, SDN‑based networks.

• Strong background in 4G/5G mobile network architecture (RAN + Core).
• Proven experience in SATCOM system architecture (space + ground).
• Deep knowledge of 3
  
  GPP architecture, protocols, and interfaces.
• Hands‑on understanding of RAN concepts (PHY/MAC, scheduling, mobility, beamforming, interference management).
• Experience producing architecture documents, system diagrams, and technical specifications.
• Strong communication and leadership skills, able to interface with stakeholders at all levels.

• Direct experience with NTN, SCS, or Direct‑to‑Cell systems.
• Familiarity with 3
  
  GPP Rel‑17+ NTN enhancements.
• Knowledge of O‑RAN (SMO, RIC, xApps/rApps) and GSMA APIs.
• Exposure to simulation, modeling, or digital‑twin tools for network planning.
• Experience with cloud‑native network orchestration and automation.
• Software engineering or scripting experience.
• Publications or patents in satellite/mobile communications.

• Competitive salary and pension scheme.
• Health insurance and equity options.
• Hybrid and flexible working arrangements.
• Opportunity to work on high‑impact, innovative projects in space and digital infrastructure.
• Exposure to cutting‑edge technologies, including AI‑driven networks and cloud mission control.
