I kid you not, this is what my Dad is.

He can do weddings, he gives sermons, he advises people on spiritual matters and tends to his congregation. But he doesn't believe in God. He is not agnostic because he doesn't really think it matters whether God exists or not. And anyways, are we going to get anywhere by thinking about it? He says that there is no way of knowing what's going to happen after we die, and thinking too much about it just prevents us from living our lives.

Yes, virginia, there is spirituality without dogma. See Unitarianism.

BTW, he used to be a programmer, but he got fed up with the industry and went back to school.
