You are right. I know some quants who have a couple of younger coders to help them with the implementation, but most of them have to code stuff on their own. Sometimes it's "quantish" code like numerical PDEs and SDEs (which is what quants should be doing), other times one has to create GUI's and such stuff which an enthusiastic teenager is more qualified to do than a PhD...
