We are seeking an experienced Senior Functional Tester with 5+ years to ensure end-to-end system quality across UI, APIs, databases, and integrations. You will validate business workflows, design comprehensive test strategies, and collaborate with development teams to deliver reliable, defect-free releases.

• Design, document, and execute functional, integration, and regression tests using Jira for management and Confluence for test plans/strategies, ensuring business workflows perform as expected across all environments.
• Perform API testing with Postman (collections/environments), Swagger/OpenAPI specs, and SoapUI for legacy systems; validate REST methods, status codes, headers, and payloads for critical EQA scenarios.

• Support automation efforts by triggering UI tests (Selenium Java, Cypress/Playwright) and API tests (RestAssured), analyzing results, and integrating with CI/CD pipelines.
• Execute performance testing with JMeter/Gatling for load/stress/spike scenarios, alongside basic security testing (role-based access, token validation) and integration testing (Solace/Kafka message validation, event-driven flows).
• Analyze logs and observability data for error patterns, report defects with root-cause insights via Jira, and track resolution to closure.
• Collaborate in daily stand-ups, refine requirements with teams/business, and proactively identify risks to maintain release quality and timelines.
