What does a Javascript test automation engineer do?

A Javascript Test Automation Engineer is responsible for designing, developing, and maintaining automated tests for web applications using JavaScript-based frameworks. They work closely with developers and QA teams to ensure that software products are reliable, performant, and meet quality standards. Their typical tasks include writing test scripts, integrating tests into CI/CD pipelines, identifying bugs, and collaborating on test strategies. These engineers often use tools like Selenium, Cypress, Jest, or Playwright to automate end-to-end, integration, and unit tests. Their work helps speed up development cycles while reducing manual testing effort.
