As far as I know he never said what job he has, but I do agree that I think he is no longer in university ( same with Amatsuki).
The thing is though for both of them, they never said they were still in university but never confirmed that they graduated from university. I think this is overall an outdated fact about them and it should probably be removed from their pages.
although this is old i wanted to show this tweet, since i wasn't sure if it implied he was still in uni or not: http://matchakame.tumblr.com/post/139943235453/mafumafus-replies-021516 here he says, "Students are doing this every day, but I am also continuing to study every day you know! Let’s do our bestー!" (via matchakame) so he may still be in university?? unsure though..
