If you want to work on "AAA" games, I don't think there are many companies left using it to this scale. An engine where those kind of games are developed almost fully in Lua, AFAIK, is Bitsquid (later Stingray by autodesk), but that has been discontinued. There are still some companies that use Bitsquid derivatives though, like Fatshark, Toadman and Arrowhead. See https://en.wikipedia.org/wiki/Bitsquid
As for non "AAA", I think https://love2d.org/ is quite popular for game jams and commercial 2d games - I haven't used myself though.
So maybe look for opportunities in companies using those engines.
