• Validate data across application screens, APIs, databases, and generated outputs.
• Cover edge cases and failure scenarios, including invalid inputs, timeouts, interrupted requests, and access restrictions.

• Build and maintain automated checks, reusable test data, and quality documentation.
• Communicate quality risks and provide clear recommendations on release readiness.

Must know

• Test-case design, manual testing, regression testing, and defect management.
• Programming in Python, Java, or a similar language, with the ability to write validation scripts.
• API testing, including HTTP, JSON, and response validation.
• SQL for data validation and troubleshooting.
• Test automation using a framework such as pytest, Selenium, or Playwright.
• SDLC, STLC, Git, and collaborative delivery practices.
• Structured problem-solving and clear communication.

Good to know

• Large language model and retrieval-augmented generation (RAG) concepts.
• CI/CD pipelines, application logs, and browser developer tools.
• Accessibility, performance, and security testing.

Relevant experience may come from professional work, internships, or substantial projects. We value someone who takes initiative and can drive quality from requirements through release.

Problem-Solving

• Strong analytical and problem-solving skills, including root-cause analysis.
• Ability to gather requirements and translate business needs into technical solutions.
• Clear communication with technical and non-technical stakeholders.
