Seconded! LuaJIT is extremely popular in gaming, you'll have no time finding work in that industry; finding people for it is hard when Javascript is so FOTM.
Stay away from EA and Amazon. Don't bother applying to unity shops either, those generally don't use Lua at all.
Lol I'm in an interesting position where I love my job and get to do cool things as an engineer. I deal with a lot of data though and have to write a lot of one-off kind of scripts frequently. This is surprisingly difficult on Windows. Python is ok, but not really what I need. Using Linux would make me really happy, but not a big enough wart to make me switch jobs.
