Your Role

The RAN Network Domain Architect will specialise in autonomous RAN operations, RAN optimisation, RAN assurance, Open RAN integration, RIC‑based automation, and AI‑driven RAN self‑optimisation.

Key Responsibilities

• Define autonomous RAN use cases including self‑optimising RAN, self‑healing RAN, interference management, energy optimisation, coverage optimisation, capacity optimisation, and fault prediction.
• Define RAN KPI models covering accessibility, retainability, mobility, throughput, latency, PRB utilisation, interference, handover success, call drop, and energy KPIs.
• Develop closed‑loop workflows for RAN optimisation using OSS, SON, RIC, EMS/NMS, and vendor automation platforms.
• Support Open RAN, near‑real‑time RIC, non‑real‑time RIC, xApps, rApps, and service management and orchestration concepts.
• Define RAN telemetry, configuration, topology, inventory, and performance data requirements.
• Support integration with RAN vendor platforms, OSS assurance systems, inventory, and orchestration layers.
• Validate RAN automation actions against policy, safety, customer impact, and operational risk.
