• Improve platform maintainability, testability, operability, resilience, and scalability, identifying opportunities for reuse, automation, and standardisation across markets and delivery teams.
• Define and validate functional and non‑functional requirements, including availability, security, performance, scalability, resilience, recoverability, and operational supportability.
• Lead and contribute to architecture reviews and governance, ensuring alignment with enterprise architecture standards, security policies, and relevant regulatory expectations.
• Identify and manage architectural risks, technical debt, obsolescence, and lifecycle concerns, defining proportionate remediation strategies.
• Maintain the architectural runway required to support sustainable delivery and future platform evolution.
• Act as a trusted architectural advisor for strategic Core Banking initiatives, technology investments, and major design decisions.
• Communicate complex architectural concepts clearly to both technical and non‑technical stakeholders, including senior management.
• Mentor architects and engineers, encouraging collaboration, knowledge sharing, and accountable technical decision‑making.
