SDETs work closely with developers to create robust test cases, identify bugs, and improve product reliability. Their role bridges the gap between traditional software testers and developers, requiring strong programming skills as well as a deep understanding of testing methodologies.

They participate in code reviews, contribute to designing robust test automation frameworks, and often pair with developers to ensure testability of new features. During sprints, SDETs write, maintain, and execute automated test suites, provide early feedback on potential issues, and help triage bugs. This close collaboration ensures faster feedback loops, higher code quality, and smoother product releases.
