Responsibilities:
This role requires strong engineering expertise in API standards, microservices orchestration, event driven patterns, and reuse of existing platform components from previous projects.
1. Technical Delivery & Systems Analysis
. Own BI FAST RFP, eMandate and Direct Debit delivery across requirements solution design integration testing rollout.
. Produce engineering ready specifications:
o API specs (REST/JSON), OpenAPI/Swagger definitions
o Microservices interface contracts, event schemas, callback payloads
o Sequence diagrams, state machines, mapping specs, error models
. Define end to end orchestration flows for:
o RFP initiation, acceptance, expiry, rejection
o Mandate lifecycle events
o Direct Debit presentment, validation, debit and return
. Specify robust pre processing logic:
o Customer/account validation
o Entitlement and authorisation checks
o Funds availability
o Fraud/AML/sanctions gating
o Limits, thresholds, duplicate suppression
o Idempotency, retry and timeout handling
2. API & Microservices Architecture
. Define API and microservices designs using existing components from previous builds:
o Payment initiation microservices
o Validation & entitlement services
o Fraud/AML adapters
o Core banking and ledger integration patterns
. Reuse existing:
o API standards (naming conventions, response structures, error formats)
o Security models (OAuth2/JWT, mTLS, signature validation)
o Eventing patterns (Kafka topics, event schemas, DLQ handling)
o Common libraries for logging, telemetry, utility functions
. Ensure microservices follow engineering principles:
o Loose coupling, clear domain boundaries
o Async event driven integration where applicable
o High availability and horizontal scalability
o Observability (structured logs, metrics, tracing)
3. User Journeys, Entitlements & Authorisation
. Define user journeys for:
o RFP initiation (corporate/merchant)
o RFP acceptance (retail/corporate)
o Mandate creation and management
o Direct Debit debit and return flows
. Align journeys with entitlements and auth rules:
o Per transaction and daily limits
o Maker checker workflows for corporates
o Channel specific access rights
. Coordinate with channel teams to maintain parity across Mobile, Internet Banking, H2H and API Banking.
4. Integration & Platform Engineering
. Design integration between:
o Payment Hub / RFP Orchestrator
o BI FAST gateway
o Mandate / Direct Debit engines
o Core banking, ledger, AML, fraud
. Use existing microservices blueprints for:
o Error propagation and code mapping
o Schema validation and transformation
o Event lifecycle management
o Callback patterns and async updates
5. Scheme, Regulatory & Risk Alignment
. Translate BI FAST RFP, eMandate and Direct Debit scheme rules into:
o Validation rules
o Reason code mappings
o Reversal/return workflows
. Embed mandatory controls:
o AML/CFT & sanctions
o Fraud monitoring
o Non repudiation and evidence capture
o TRM, cybersecurity and audit trail requirements
6. Testing, Deployment & Operational Readiness
. Lead SIT/UAT/E2E test scenario design for:
o RFP acceptance settlement flows
o Mandate lifecycle
o Direct Debit presentment/return/dispute cases
o Timeouts, retries, negative tests
. Work with Engineering & Ops to ensure:
o Monitoring dashboards and alerts
o Reconciliation and exception queues
o Runbooks for replay, retry and operational fixes
. Support scheme certification and phased deployment.
