[@Zelosse]Like Sprigs said there is a precedent in Overlord for humanoid doll like creatures but they're all magical in origin, and not proper classes from what I've seen I can hand wave it for the sake of being nice if you're insistent but machinery to my knowledge is all Medieval meaning nigh non existent. There is not even steampunk flinklocks in the setting. The closest I've seen is distilleries.
