„Meister“ (literally “master” in English) is just the certificate you get after finishing some vocational trainings in Germany (includes theory and practice). Vocational training is still somewhat widespread in Germany (for jobs like mechanics, hairdressers, even sys admins, some more rote programming jobs, …) also as an alternative to going to university. Now, I’m not sure whether typical assembly line workers have that kind of education (probably not? but I’m not sure), so having someone with this kind of education assemble your engine for you might be a step up, but I also think there is a mismatch going on here between what the English words seem to imply and what the German word means.
