Job description

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
