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.
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
- 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 local and cross-border payments 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.
