It’s a masseur. In the good old days every JCC and steam bath had one who gave rubdowns (massages) in their health clubs. You can still find this service at some JCCs as well as goyische Ys and Russian Bath houses.
I grew up in CT. We belonged to a country club, they employed a full time locker room attendant who also was trained to give massages. Nothing like a schvitz followed by a massage.
