Or both are correct. In my opinion, both are correct, though. Since no takes a singular noun and plural noun too. But the thing is which makes more sense ?
More usual is She doesn't have a job. However, I suppose you could say either She has no job or She has no jobs. I don't know if either makes more sense, since they both mean the same thing (She doesn't have a job).
