As a localization QA tester, your job is to test software functionality and search for defects before your company releases the software to the end user. In this role, you may use a computer to test and evaluate the software, create a plan to test each function, and provide information and feedback on any linguistic issues. In this context, localization usually refers to translating software between different languages. This requires editing menus, information displays, documentation, and other aspects of the software without introducing new errors. Localization QA testers often work in teams for larger projects. Some testers specialize in specific types of software, such as medical programs or video games.
