Job Description

The incumbent will lead the technical analysis, microservices integration design, and end-to-end delivery of Corporate Internet Banking projects. This role requires strong engineering expertise in API standards, microservices orchestration, event-driven patterns, and reuse of existing platform components from previous projects.

Key Responsibilities

1. Technical Delivery & Systems Analysis

• Own UOB Corporate Banking channel (infinity program and projects) requirements → solution design → integration → testing → rollout.
• Produce engineering-ready specifications:
  • API specs (REST/JSON), OpenAPI/Swagger definitions
  • Microservices interface contracts, event schemas, callback payloads
  • Sequence diagrams, state machines, mapping specs, error models
• Define end-to-end orchestration flows for:
  • Pre-Payment initiation, acceptance, expiry, rejection
  • Entitlement and Auth Matrix lifecycle events
  • Template, Past Payment, Bene Master
  • Digital assets flows (wallet mgmt), Blockchain
• Specify robust pre-processing logic:
  • Customer/account validation
  • Entitlement and authorisation checks
  • Funds availability
  • Limits, thresholds, duplicate suppression
  • Idempotency, retry and timeout handling

2. API & Microservices Architecture

• Define API and microservices designs using existing components from previous UOB 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 UOB'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:
  • Pre-Payment Workflow like payment initiation
  • Beneficiary Master
  • Bulk Processing
  • Digital assets management
• 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
  • Payment gateway
  • Core banking, ledger, AML, fraud
  • Tokenized Deposit, Blockchain
• Use existing microservices blueprints for:
  • Error propagation and code mapping
  • Schema validation and transformation
  • Event lifecycle management
  • Callback patterns and async updates

5. Testing, Deployment & Operational Readiness

• Lead SIT/UAT/E2E test scenario design for:
  • Corporate Internet Banking Channels
  • Entitlements, Auth matrix
  • Pre-payment flow like payment initiation, validation and submission
  • 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 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 behaviour.
• Clear, engineering-ready specifications enabling smooth developer adoption.
• Strong governance alignment across Product, Engineering, Operations and Risk.

Key Skills & Experience

• At least 12 years in payment systems analysis with experience in Corporate Internet Banking, Entitlement and pre-payment workflow or similar.
• Preferably to have experience with blockchain and digital assets with regards to pre-payment initiation
• Strong engineering/technical skills:
  • API design (REST/JSON, OpenAPI/Swagger)
  • Microservices architecture
  • 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.
