Automation Test Engineer

PROJECT

Design, build, and maintain automated test solutions for payments platforms to improve release confidence, reduce regression effort, and ensure high-quality delivery across critical payment processing journeys. You’ll combine strong Java-based automation skills with solid payments domain knowledge to create meaningful, reliable automated coverage aligned to real-world processing and controls.

YOU WILL

• Build and maintain automated test frameworks and suites using Java and appropriate automation tools (UI, API, and integration layers).

• Translate functional payment requirements into automated test cases, ensuring coverage of end-to-end flows and edge cases.

• Automate testing for payment types and components such as credit transfers, direct debits, SWIFT/ISO 20022 messages, payment gateways, validation, routing, and posting (scope depends on platform).

• Create robust API and service-level automation (e.g., REST/SOAP), including contract and schema validation where relevant.

• Validate payment processing rules: cut-off times, value dates, charges/fees, FX (if applicable), limits, sanctions/AML screening touchpoints, returns/recalls, reversals, rejects/repairs, and exception handling.

• Implement test data strategies for payments (synthetic data, masking, data seeding), including correlation of transactions across systems.

• Integrate automated tests into CI/CD pipelines; enable unattended execution, reporting, and quality gates.

• Analyse failures quickly (logs, message traces, database queries where permitted) and raise high-quality defects with clear evidence.

• Collaborate with Product Owners, Developers, BAs, and Ops to define acceptance criteria, test approach, and release readiness.

• Maintain test documentation: automation coverage, traceability, and execution dashboards/metrics.

MUST HAVE

• Strong hands-on experience building automation in Java (clean code, OOP, design patterns).

• Experience with common automation tools/frameworks such as:

  • JUnit/TestNG, Cucumber/BDD (optional)

  • Selenium/Playwright (UI, where applicable)

  • REST Assured, Postman/Newman, SoapUI (API)

  • Maven/Gradle, Git, Jenkins/GitLab CI/Azure DevOps

• Understanding of test automation best practices: maintainability, flakiness reduction, parallel execution, and environment resilience.

• Familiarity with observability and diagnostics: logs, tracing, monitoring tools (e.g., Splunk/ELK), and basic SQL.

• Working knowledge of payment processing concepts and lifecycles.

• Familiarity with payment standards and formats (as relevant): ISO 20022, SWIFT MT/MX, local clearing formats.

• Understanding of operational and risk considerations: sanctions screening touchpoints, auditability, resiliency, and high availability expectations.

NICE TO HAVE

• Performance testing exposure (e.g., JMeter/Gatling) for payment throughput and latency.

• Containerisation and test environment tooling (Docker, Kubernetes basics).

• Experience testing event-driven architectures (Kafka) and asynchronous processing patterns.

• Experience with test data management tools

• Knowledge of reconciliation, ledger posting, and downstream reporting impacts.
