What term is used for a person who ensures that developed software meets required specifications?

The term "Quality Assurance Tester" refers specifically to an individual responsible for ensuring that software products adhere to required specifications and quality standards. This role is critical in the software development lifecycle, as it involves thoroughly testing applications to identify defects and ensure that they function as intended before they are released. Quality Assurance Testers design test cases, execute them, and document the results, providing feedback to development teams to facilitate improvements.

In contrast, the other roles mentioned focus on different aspects of software development. A Systems Analyst typically works on designing systems, understanding user requirements, and translating these into specifications for developers. A Database Administrator is responsible for managing and maintaining database systems, ensuring their performance, security, and reliability, rather than directly testing application software. A Frontend Developer primarily focuses on building the user interface and experiences of applications, concentrating on the graphical and interactive aspects rather than the overarching quality assurance processes.
