    • Build and maintain structured API test suites with workflows and chained requests.

    • Use environments, variables, and reusable test data.

    • Run and automate API tests using Newman (CLI) and generate reports.

    Debugging & Bug Reporting

    • Investigate issues using logs, network traffic, and API responses.

    • Report bugs with clear steps, expected vs. actual results, and severity.

    • Collaborate with developers to confirm and validate fixes.

    Process Improvement

    • Participate in grooming, sprint planning, and release activities.

    • Contribute to QA documentation, strategy, and continuous improvements.

    • Support automation engineers with scenarios and test data.

    What You Bring

    Must-Have

    • 4+ years in manual and technical QA.

    • Strong understanding of HTTP, REST APIs, JSON, and client-server communication.

    • Ability to automate API test suites using Newman or similar.

    • Strong UI testing skills and proficiency with browser dev tools.

    • Ability to run SQL queries for backend validation.

    • Excellent communication, analytical skills, and attention to detail.

    Nice-to-Have

    • Experience with performance or load testing tools.

    • Familiarity with microservices.

    • Experience with Playwright, Cron, or Git workflows.
