QA Tester needed for macOS app and Windows applications.

We have recurrently launched our MVP on mac App Store as well as Microsoft store and looking for an experienced QA Tester than can test the app regularly for both mac and windows. We are looking for someone that is very detail oriented and also wants to be part of a team and work with on a long-term arrangement as we grow the product. It is a huge plus if you have both mac and windows to use to test the application.
