QA - Tester - Ongoing

I'm looking for a QA Tester Engineer willing to work on an ongoing basis to test my mobile app's functionality. This will require a medium-term scope of testing, where the tester is responsible for ensuring that the app is bug-free and meets the goals of my company and our users. The tester must have a detailed knowledge and experience in the software development lifecycle and must understand functional, security, and usability testing. The tester will be working remotely and is expected to have excellent knowledge of software testing methods. The person must also have a proven ability to manage deadlines and produce quality results in a timely fashion. We require a reliable and dedicated individual who is able to put in the effort to meet our expectations.
