Overview We are looking for a user-interface tester with the initiative to take a written brief describing how a feature is intended to behave and independently turn it into their own test plan — identifying the scenarios, edge cases, and checks that confirm the application works as it should.

The public-facing web app I’m about to launch needs a final, end-to-end quality sweep.
