Quality assurance engineers
Detail focused. Systematic. Reliable. Quality assurance engineers support every stage of software development. They plan realistic testing approaches, build and maintain automated and manual tests, and study defects to understand root causes. Working closely with developers and analysts, they check that requirements are clear, edge cases are covered, and new changes do not break existing behavior. Continuous QA activity inside the delivery process keeps failures rare, feedback loops short, and systems stable as they evolve.
