Yes, "what is it that you do?" expresses the same general meaning as "what do you do?". There is just a slight difference in nuance between these two phrases. "What is it that you do " is a little more informal and can sometimes be used to imply that the person asking does not think the other person does anything that important. However, it is not always used with this intention and often depends on the tone of voice.
