What is a privacy engineer?

In recent years, the term “privacy engineering” has entered the professional lexicon. It’s a term that’s bandied about, usually with high regard -€” heck, it even has a Wikipedia page -” but it’s not always clear what a privacy engineer is or does, at least generally speaking.

Is a privacy engineer someone who has a PhD in computer science and codes notions of privacy (whatever that is) into IT systems, services and products? Or is the work of a privacy engineer more broad in scope than that?
