Senior Middleware & Integration Test Engineer (Banking)

K20s Kinetic Technologies

Key Responsibilities

Specification Analysis: Deconstruct complex technical and functional specifications for middleware components, microservices, and orchestration flows to identify potential integration bottlenecks.

API Lifecycle Testing: Design and execute comprehensive test suites for RESTful and SOAP services, focusing on payload validation (JSON/XML), header manipulation, and robust error-handling protocols.

Banking Ecosystem Integration: Validate mission-critical integrations between Middleware/ESB and:

Core Banking Systems: (e.g., Finacle, Flexcube, T24).

Payment Gateways: Local and international rails including SARIE (Instant Payments), SADAD, ESAL, and SWIFT.

Digital Channels: Ensuring 100% uptime for Mobile and Internet Banking API consumers.

Security & Auth Validation: Rigorously test authentication and authorization layers, including OAuth2, JWT, and mTLS, ensuring compliance with SAMA Cybersecurity Frameworks.

Message Queue Orchestration: Verify asynchronous processing and data integrity across messaging queues such as IBM MQ, RabbitMQ, or Apache Kafka.

Performance Benchmarking: Validate API performance against SLAs, monitoring rate limits, throttling behaviors, and response latency under peak load conditions.

End-to-End Traceability: Establish and maintain a traceability matrix that links business requirements to specific API endpoints and ESB flows, ensuring 100% test coverage for complex banking journeys.

Data Integrity & Security Testing: Perform deep-dive validation of data transformations between heterogeneous systems (e.g., XML to JSON) while ensuring sensitive PII is handled according to SAMA Data Privacy standards.

Technical Interface Liaison: Act as the primary technical point of contact for external fintechs and third-party providers, managing the onboarding and validation of their APIs into the bank s middleware ecosystem.

Cross-Functional Triage: Lead "Integration Triage" sessions, bringing together Core Banking, Digital Channel, and Infrastructure teams to resolve "finger-pointing" during complex defect investigations.

Technical Qualifications & Experience

Middleware Expertise: Minimum 6+ years of experience testing ESB platforms (e.g., MuleSoft, TIBCO, WSO2, or IBM IIB).

Tool Proficiency: Advanced hands-on experience with Postman (scripting), SoapUI, Swagger, and JMeter.

Banking Domain: Strong understanding of Middle Eastern banking processes, specifically around Open Banking initiatives and retail/corporate payment workflows.

Database & Logs: Proficiency in SQL and log analysis tools (e.g., Splunk, ELK Stack) to perform root-cause analysis for failed integration flows.
