• Develop network roadmaps and transition architectures that balance strategic direction, technical debt, service continuity and delivery priorities.
• Provide architectural oversight from discovery and options analysis through implementation, migration and live service.
• Document network architectures, traffic flows, trust boundaries, technical options, decisions, dependencies and transition states clearly for technical and non‑technical audiences.
• Define requirements for network observability, performance monitoring, capacity management, configuration control, resilience testing and incident response.
• Collaborate with cloud platform, infrastructure, engineering, security, service management and delivery teams to ensure designs can be implemented and operated effectively.
