employed (by a university) as a moral philosopher. Interestingly the institute they work for is ethically dubuous (because of how it's funded, not the teaching content)
It's a rather small field, but IIRC, I had a philosophy professor in college whose specialty was the Ethics, and he had a sideline consulting with hospitals as a medical ethicist. He was also brilliant-- In the course I took with him we covered scientific ethics, one of the more memorable of my academic experiences.
