2. Cloud Core Banking Implementation: Drive ledger‑related components in cloud‑native core banking platforms (e.g., Thought Machine, Temenos, Mambu, Tuum, Finastra), configure and validate posting rules, journal entries, and accounting flows, and collaborate with platform vendors and SI teams on solution design and delivery.
3. Integration & Data Flow: Design integration between core banking engine, payments systems (FPS, CHAPS, SEPA, SWIFT), channels and middleware, financial reporting / GL systems, and ensure real‑time reconciliation and data consistency.
