RAN Architect

Overview

Lead architecture, design and lifecycle of multi‑tenant virtualized 4G/5G RAN platforms.

Key Responsibilities

• network automation
• traffic segregation
• son management
• ran architecture
• vnf orchestration
• performance reporting

Tasks

-Collaborate with Technology teams dedicated to: NMS development; Data Engineering; Data Science; and AI; to drive automation and closed-loop optimisation of network management processes. -Oversee the implementation of traffic segregation and security controls across transmission links, in line with JOTS/NHIB standards and Boldyn’s cyber-security policies. -Continuously optimise network performance, leveraging real-time analytics, customer experience metrics, and support system feedback. -Provide Tier 3 Service Management expertise, supporting incident resolution, root cause analysis, and continuous improvement initiatives. -Work closely with the Network Operations Centre (NOC) and R&D teams to define, implement, and refine maintenance and operational procedures that underpin system-wide performance. -Manage Self-Organising Network (SON) settings and policies, leveraging automation to enhance network efficiency and resilience. -Work in close articulation with IP architects to define transmission requirements, select appropriate technologies (e.g., private leased lines, Ethernet services, IPsec VPNs), and ensure seamless integration with the overall network architecture. -Lead the architecture and evolution of Boldyn’s multi-tenant Neutral Host RAN platforms, ensuring robust support for 4G/5G virtualised deployments across enterprise and high-density venues. -Serve as design authority for all RAN elements, including eNodeB/gNodeB, Small Cells, gateways, and associated virtual network functions (VNFs). -Define the best practices to operate and optimise virtualised network functions (VNFs), ensuring seamless orchestration, scaling, and lifecycle management within the RAN domain. -Act as product owner for CaaS RAN (multi-vendor), HDD CaaS RAN (JMA XRAN), and Private Networks RAN solutions, driving roadmap, feature integration, and vendor alignment. -Manage technical engagement with the partner ecosystem, including MNOs, technology vendors, and service providers, ensuring effective communication and alignment on delivery and operational models. -Specify and validate transmission topologies, including redundancy, failover, and capacity planning for high-availability service delivery. -Own and maintain all architectural documentation, including High-Level Design (HLD), Low-Level Design (LLD), and Configuration Information Questionnaire (CIQ), ensuring alignment with industry standards and customer requirements. -Establish and govern network configuration management practices, including parameter audits, feature trials, and change control across the RAN estate. -Support troubleshooting and performance optimisation of transmission networks, collaborating with cross-functional teams to resolve issues and enhance service quality. -RAN Capacity Management, Feature and Parameter trial -Defining and implementing processes for Performance reporting -Define and enforce network performance management frameworks, overseeing KPI monitoring, SLA adherence, and optimisation strategies at both network-wide and site-specific levels.
