• Review requirements, user stories, and design documents to create detailed and comprehensive test cases and checklists
• Perform functional, integration, UI/UX, and regression testing across web, data, 3d party apps and/or API layers.
• Test on multiple browsers, devices, and screen resolutions to ensure cross-platform consistency
• Execute manual test cases and report issues with clear reproduction steps and severity levels
• Verify fixes and perform retesting and smoke testing
• Maintain test case repositories (e.g., TestRail, Zephyr, Xray, etc.)
• Perform basic API testing using tools like Postman
• Use developer tools (e.g., Chrome DevTools, browser console) to investigate issues

• Support release validation in redesign, staging and production environments or any other required.
• Collaborate with developers and product managers to ensure test coverage and align QA efforts with release goals
• Collaborate with business, customer success to ensure the test coverage and align QA efforts with business goals.
   

Automation & AQA Responsibilities

• Develop and maintain automated test suites for UI and API layers using frameworks like Playwright, Cypress, or Selenium
• Integrate test automation into the CI/CD pipeline to enable fast and reliable deployments
• Prioritize what to automate based on risk, stability, and ROI, complementing manual testing
• Validate data flows and transformation logic in data-driven applications by writing automated assertions against APIs and backend responses
• Build reusable utilities and selectors to support robust and maintainable test scripts
• Work closely with developers to ensure testability and coverage of edge cases
• Use version control (e.g., Git) and test reporting tools (e.g., Allure, TestNG reports) to ensure traceability
• Support debugging and root cause analysis by capturing logs, screenshots, and network traces during test execution
• Maintain a hybrid approach, knowing when to use exploratory/manual testing alongside automation to uncover UI/UX or logic-related issues

Data-Driven Application Testing

• Validate the accuracy, completeness, and integrity of data throughout the user journey
• Perform data validation across frontend, backend, and database layers, including comparing displayed data with source systems or API responses
• Ensure business rules and data logic are correctly applied (e.g., filters, transformations, aggregations)
• Test the impact of edge cases and malformed data inputs on application behavior
• Perform SQL-based verification (or through data exports) to confirm data correctness, where applicable
• Validate data syncing between systems, especially in applications that consume or expose third-party data via APIs
• Monitor how updates to records, entries, or data states reflect across the application (e.g., state transitions, user-based data visibility)

Non-Technical Responsibilities

• Participate in daily stand-ups, sprint planning, and retrospectives to represent QA priorities
• Communicate bugs and quality concerns clearly to cross-functional teams
• Proactively raise red flags if requirements are unclear, incomplete, or inconsistent
• Help define and improve QA processes, checklists, and acceptance criteria
