The role combines extensive domain expertise and technical capabilities to influence the team to deliver a great customer experience.

Responsibilities

• Lead end-to-end solution architecture and design, taking solutions from discovery and requirements through detailed design, build, testing, production deployment and transition.
• Define solution architectures, integration patterns, technology options and Key Design Decisions, supported by clear architecture documentation and diagrams.
• Design API-first, microservices and event-driven solutions across network and OSS/BSS environments, including ingress and egress APIs, asynchronous messaging and integration contracts.
• Work closely with TPOs, Mission Leads, Engineering Leads, delivery squads, Security teams and other stakeholders to translate business and technical requirements into practical solution designs.
• Facilitate architecture and design reviews, communicate architectural decisions and trade-offs, and resolve technical dependencies across upstream and downstream systems and delivery teams.
• Review functional and non-functional requirements, ensuring scalability, reliability, resilience, observability, security, data protection and operational supportability are built into solution designs.
• Lead security endorsement and architecture governance activities, working with security architects and risk teams to address authentication, authorisation, encryption, compliance and data protection requirements.
• Support engineering teams throughout implementation by reviewing technical designs, interfaces and stories, clarifying architectural intent and ensuring delivery remains aligned with the agreed architecture.
• Manage architectural risks, dependencies and technical constraints throughout delivery, including coordinating between engineering, security, delivery and stakeholder groups.
• Support production readiness and transition planning, using phased implementation approaches where required to enable safe and effective production delivery.
• Lead architecture for legacy transformation, simplification, modernisation and cloud migration, identifying opportunities to move towards sustainable future-state architectures.
• Evaluate emerging technologies and alternative design approaches, recommending solutions aligned with strategic architecture direction and long-term platform objectives.
