English to French Bus/Financial Gaming/Video-games/E-sports Casino

The context is a discussion where one character (who works in a casino) says that he has a meeting with his 'inspector' (US English).

I've looked on a couple of casino sites and it seems as though this is a specific position within a casino- someone who is in charge of several tables.

I haven't been able to find a French (France) equivalent- thanks in advance for any suggestions.
