What is a QA engineer?

QA Engineers, or Quality Assurance Engineers, are professionals responsible for ensuring that software products meet established quality standards before they are released to customers. They design and execute tests, identify bugs or issues, and work closely with development teams to resolve problems. QA Engineers play a crucial role in the software development lifecycle by preventing defects, improving product reliability, and ensuring a smooth user experience. Their work may involve manual testing, automated testing, and creating test documentation.
