The Role
The NGIN Telecom Solution Architect role is critical for the design, governance, and evolution of Next Generation Intelligent Network (NGIN) platforms that support business-critical telecommunications services and customer solutions.

- Provide technical leadership for the modernization and rationalization of legacy telecom platforms, supporting strategic transformation and migration programmes.
- Assess current-state architectures, identify technical debt, and define target-state roadmaps that improve operational efficiency, service stability, and business agility.
- Collaborate with business stakeholders, product owners, network engineering teams, vendors, and delivery partners to translate business requirements into robust technical solutions.
- Produce and maintain architecture artefacts including solution designs, high-level and low-level designs, technology roadmaps, interface specifications, and architectural standards.
- Ensure the integration of NGIN platforms with OSS/BSS systems, CRM platforms, billing systems, customer channels, and external partner ecosystems.
- Provide architecture governance throughout the project lifecycle, ensuring compliance with enterprise architecture principles, regulatory requirements, security policies, and operational standards.
- Act as the technical authority for NGIN-related solutions, providing expert guidance on platform capabilities, technology selection, solution feasibility, and risk mitigation.
- Support incident resolution, problem management, and root cause analysis activities for critical telecom services, ensuring minimal impact on customers and business operations.
- Lead architecture reviews, technical assurance activities, and design approvals to ensure solution quality and consistency across programmes.
- Identify opportunities for service improvement, automation, simplification, and cost optimization across telecom platforms and operational processes.
- Support capacity planning, resilience assessments, disaster recovery strategies, and performance optimization initiatives to maintain service reliability.
- Mentor engineering and design teams, promote best practices, and facilitate knowledge sharing to strengthen organizational capability and reduce dependency on key individuals.
- Provide strategic input into technology investment decisions, vendor evaluations, platform upgrades, and long-term telecommunications transformation roadmaps.
