What is a software development engineer in test?

A Software Development Engineer In Test (SDET) is a professional who combines software development skills with expertise in testing to ensure the quality of software products. SDETs design, develop, and maintain automated test frameworks, write test scripts, and work closely with developers to identify and resolve defects early in the software development lifecycle. They play a critical role in integrating testing into the development process, improving test coverage, and enabling continuous integration and delivery. SDETs often have strong programming abilities and a deep understanding of both software engineering and quality assurance best practices.
