Is this weird in any way? I live in EU land, but this does not seem too uncommon. As a developer Ive had assignments where I only wrote unit test, another where I was reponsible for daily CI running well (though both moved towards development eventually). I heard just the other day about a competitor where you did not write your own test code.
But yes, before that it would be not at all unusual to have “test engineers” or other technical staff whose entire responsibility laid with setting up test environments and running QA of products. These people did not do product dev, though they may have been involved in writing supporting test platform libraries or even maintaining test infrastructure (like IBM Jazz).
Even today in the U.S. companies that haven’t fully jumped onto newer development practices probably still have QA and/or test departments.
I just checked LinkedIn and they have quite a few job listings in this vein. Which makes sense: in the "AI and YOLO" development lifecycle, automated testing is more important than ever.
