Throughout my career, I’ve noticed that quality/test engineering is usually seen as a bottom-of-the-barrel discipline, something that someone should want to be promoted out of rather than someplace to end up. I find that really strange.
It takes a lot of skill to look at other peoples' code and write tests to exercise it and determine correctness, and to do it well. And to have exacting standards about code quality and testability of the code in the first place.
Nearly everywhere I’ve worked, though, test engineers have been incredibly junior and not particularly skilled. Which made it part of a self-fulfilling vicious cycle; test engineers do poor-quality work (and don’t seem to bring much value to the actual product development), so low-calibre programmers end up being put in those roles, and so then they continue to do poor-quality work. Test engineering seems to be treated as glorified QA in most places.
