Bringing up breast pumping when getting a new job?

So I intend to start looking for a job once im done with being in physical school, I'll be switching to online for my last three classes. The only thing is that when I will be starting to look for a job, I will also be (hopefully) breastfeeding. When I go back to work of course I'll need to pump as I intend to try to find a full time job. How should I bring this up in applying for a job or an interview if I'm accepted for one? Should I wait until I'm hired to ask for time and a place for breast pumping?
