Key Responsibilities

  • Plan, design, and develop automated test scripts for web applications, mobile, and APIs.
  • Perform manual exploratory and regression testing to identify system failures prior to deployment.
  • Collaborate with developers and product owners during grooming sessions to ensure features are highly testable.
  • Identify, document, and track bugs with detailed technical logs inside project management tools.
  • Configure and maintain continuous integration (CI/CD) pipelines to trigger automated test suites seamlessly.

Requirements & Skills

Solid experience with modern test automation frameworks like Cypress, Playwright, or Selenium.Proficiency in RESTful API testing using tools like Postman, Insomnia, or code-based libraries.Practical knowledge of programming languages used for automation, such as JavaScript, TypeScript, Python, or Java.Familiarity with CI/CD pipelines (GitHub Actions, GitLab CI, or Jenkins) and Git version control.Critical thinking, extreme attention to detail, and excellent interpersonal communication for cross-functional collaboration.

Day in the Life

A QA Engineer's day typically begins with the daily stand-up meeting, aligning on tasks and identifying development blockers. Next, the engineer analyzes new user stories ready for verification, drafts test scenarios, and executes manual or automated validations. A significant portion of the day is spent writing and refactoring automation scripts for the regression test suite, ensuring new updates don't break existing features. Towards the end of the day, they review execution logs from CI/CD pipelines, log detailed bug reports in Jira, and collaborate closely with developers to reproduce and resolve critical defects.

Frequently Asked Questions

What is the difference between a QA Analyst and a QA Engineer?

While terms are often used interchangeably, a QA Analyst typically focuses on test strategies, planning, and manual/functional testing. A QA Engineer has a more technical background, focusing heavily on writing test automation scripts using code, integrating tests into CI/CD pipelines, and executing non-functional performance testing.

Do I need to know how to code to be a QA Engineer?

Yes. Test automation is one of the most highly demanded skills in QA engineering today. Knowing programming languages such as JavaScript, TypeScript, Python, or Java is essential for creating and maintaining robust scripts within modern frameworks like Playwright and Cypress.
