As a Middleware Test Engineer, you will be responsible for validating the interfaces that connect our core banking systems with modern digital channels. You will ensure the reliability, security, and performance of our Enterprise Service Bus (ESB) and API layers, facilitating seamless financial transactions across the Saudi banking ecosystem.

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.
