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 including 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.

• Location: This is a permanent role with Capgemini, offering a hybrid working model. The client is based in Newbury and occasional travel to the client site will be required.

If you're excited about this role but don't meet every requirement, we stillencourage you to apply, your unique experience could be just what we need.
