What will you do? Own functional, regression, integration, system, and end-to-end testing for complex applications and backend workflows.
Analyze business and technical requirements, identify test scenarios, assess test coverage, and highlight requirements or design gaps early in the delivery lifecycle.




Create and maintain high-quality test documentation including test plans, detailed test scenarios, test cases, traceability matrices, test evidence, execution reports, and release-quality summaries.
Perform database and backend validation using SQL to verify data integrity, transformations, transactional accuracy, and downstream processing results.
Validate APIs and service integrations using tools such as Postman and support automation of repeatable API and backend regression scenarios.
Develop, maintain, and execute automated tests using appropriate UI, API, or backend automation frameworks; contribute to improving regression efficiency and coverage.
Perform defect analysis and triage, provide clear reproduction details and supporting evidence, and collaborate with engineering teams through resolution and retesting.
Validate file-based workflows, scheduled jobs, and inter-system data exchanges, including reconciliation of source and target results.
Estimate testing effort, plan test execution, identify delivery risks, and communicate testing status and quality concerns to project and QA leads.
Mentor less experienced QA engineers on functional testing practices, test design, documentation quality, defect reporting, and effective validation techniques.
Contribute to QA process improvements, reusable test assets, automation candidates, and continuous improvement initiatives across the team.
