• Develop and maintain automated, integration, regression, API, system, and end-to-end tests.
• Validate workflows across frontend applications, backend services, APIs, databases, and event-driven integrations.
• Perform positive-path and negative-path testing, including malformed or incomplete payloads, validation errors, boundary conditions, and edge cases.
• Test authentication, authorization, validations, integrations, and error-handling behavior.
• Use SQL and other validation methods to verify data accuracy and integrity.
• Support performance and security-testing activities and collaborate on the remediation of findings.
• Investigate defects, document reproducible steps, assess their impact, and work with developers to verify fixes.
• Maintain test data, test environments, and repeatable testing processes.
• Produce clear test evidence and release-verification documentation.
• Support User Acceptance Testing and release-readiness activities.
• Contribute to requirements traceability, design reviews, quality controls, and regression assurance.
• Integrate automated tests into CI/CD workflows where applicable.
• Communicate quality status, coverage gaps, release risks, and unresolved defects clearly.

Required skills and experience:

• Professional experience in software QA or Test Engineering for web applications and APIs.
• Experience with test design, planning, execution, and documentation.
• Experience with functional, integration, regression, API, and end-to-end testing.
• Experience with API-testing tools such as Postman or equivalent.
• Experience with test-automation frameworks and scripting.
• Understanding of databases, SQL, and data validation.
• Experience documenting, prioritizing, and tracking defects.
• Understanding of acceptance criteria, coverage, requirements traceability, and release validation.
• Experience working within Agile software-development teams.
• Strong analytical, documentation, and communication skills.
• Advanced English communication skills.

Nice to have:

• Playwright, Cypress, Selenium, or equivalent automation tools.
• Performance-testing experience.
• Security-testing experience.
• Testing of Azure-based or cloud-hosted applications.
• Experience testing event-driven or multi-service applications.
• Integration testing across external systems.
• Automated testing integrated into CI/CD pipelines.
• Experience in enterprise or regulated environments.
• Experience with formal requirements traceability, design reviews, or documented verification evidence.
