The posting
Role: System Analyst
Job Requisition Number: IS-96550
Job Level: > 10 yearsof relevant experience (L4)
Location: Singapore
Key Responsibilities:
● Lead the technical analysis, microservices integration design, and end-to-end delivery of BI-FAST Request for Payment (RFP), e Mandate, and Direct Debit capabilities for Indonesia. 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, e Mandate and Direct Debit delivery across requirements → solution design → integration → testing → rollout.
● Produce engineering-ready specifications:
○ API specs (REST/JSON), Open API/Swagger definitions
○ Microservices interface contracts, event schemas, callback payloads
○ Sequence diagrams, state machines, mapping specs, errormodels
● Define end-to-end orchestration flows for:
○ RFP initiation, acceptance, expiry, rejection
○ Mandate lifecycle events
○ Direct Debit presentment, validation, debit and return
● Specify robust pre-processing logic:
○ Customer/account validation
○ Entitlement and authorisation checks
○ Funds availability
○ Fraud/AML/sanctions gating
○ Limits, thresholds, duplicate suppression
○ Idempotency, retry and timeout handling
2. API & Microservices Architecture
● Define API and microservices designs using existing components from previous builds:
○ Payment initiation microservices
○ Validation & entitlement services
○ Fraud/AML adapters
○ Core banking and ledger integration patterns
● Reuse existing:
○ API standards (naming conventions, response structures, error formats)
○ Security models (OAuth2/JWT, mTLS, signature validation)
○ Eventing patterns (Kafka topics, event schemas, DLQ handling)
○ Common libraries for logging, telemetry, utility functions
● Ensure microservices follow the Bank’s engineering principles:
○ Loose coupling, clear domain boundaries
○ Async event-driven integration where applicable
○ High availability and horizontal scalability
○ Observability (structured logs, metrics, tracing)
3. User Journeys, Entitlements & Authorisation
● Define user journeys for:
○ RFP initiation (corporate/merchant)
○ RFP acceptance (retail/corporate)
○ Mandate creation and management
○ Direct Debit debit and return flows
● Align journeys with entitlements and auth rules:
○ Per-transaction and daily limits
○ Maker-checker workflows for corporates
○ 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:
○ Payment Hub / RFP Orchestrator
○ BI-FAST gateway
○ Mandate / Direct Debit engines
○ Core banking, ledger, AML, fraud
● Use existing microservices blueprints for:
○ Error propagation and code mapping
○ Schema validation and transformation
○ Event lifecycle management
○ Callback patterns and async updates
5. Scheme, Regulatory & Risk Alignment
● Translate BI-FAST RFP, e Mandate and Direct Debit scheme rules into:
○ Validation rules
○ Reason code mappings
○ Reversal/return workflows
● Embed mandatory controls:
○ AML/CFT & sanctions
○ Fraud monitoring
○ Non-repudiation and evidence capture
○ TRM, cybersecurity and audit trail requirements
6. Testing, Deployment & Operational Readiness
● Lead SIT/UAT/E2E test scenario design for:
○ RFP → acceptance → settlement flows
○ Mandate lifecycle
○ Direct Debit presentment/return/dispute cases
○ Timeouts, retries, negative tests
● Work with Engineering & Ops to ensure:
○ Monitoring dashboards and alerts
○ Reconciliation and exception queues
○ Runbooks for replay, retry and operational fixes
● Support scheme certification and phased deployment.
Success Measures
● High-quality BI-FAST RFP, e Mandate and Direct Debit delivery with minimal defects.
● Strong reuse of existing microservices, reducing build complexity and time-to-market.
● High STP rates, stable performance and consistent low-latency behavior.
● Clear, engineering-ready specifications enabling smooth developer adoption.
● Strong governance alignment across Product, Engineering, Operations and Risk.
Key Requirements:
● 7–12 years in payment systems analysis with experience in RFP, e Mandate, Direct Debit, or similar.
● Strong engineering/technical skills:
○ API design (REST/JSON, OpenAPI/Swagger)
○ Microservices architecture
○ Event-driven patterns (Kafka or equivalent)
○ State machine and sequence diagram modelling
○ HA/DR and low-latency systems
● Experience integrating with AML, fraud, entitlements and ledger systems.
● Ability to reuse and extend existing platform components and code frameworks.
Technical Skills:
● Open API, Microservices
● Java
