Staff tools on mobile do exist, however they are much less intuitive to use than on PC and are restricted to high staff.
As previously mentioned, a large amount of staff work is done using RC, which is quite awkward to use on mobile.
Also, there's a large amount of functions which simply can't be done using mobile, implementing those functions onto mobile would use up a lot of resources which would better be spent on developing the game.
So in short, this won't ever happen, unfortunately.
