  • Assess and define test framework(s) and tools
  • Create pipelines for Continuous Testing
  • Develop and maintain automated regression tests and manage false positives/fragile tests
  • Execute manual and exploratory testing and mitigate security vulnerabilities

You will implement test automation frameworks and pipelines for Continuous Testing in Agile teams, covering integration, system, performance, and compatibility testing.
