Automation Test Engineer

PROJECTDesign, 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 WILLBuild 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 HAVEStrong 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 DevOpsUnderstanding 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 HAVEPerformance 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 toolsKnowledge of reconciliation, ledger posting, and downstream reporting impacts.OUR OFFERRelocation package (4500 PLN total value), paid in three installments (1500 PLN per month)Benefits: Extended medical care (over 2000 medical facilities in Poland, 80 in Kraków) for you and your family; Multisport Benefit card; Life insurance
