By "working under" do you mean having an engineer report directly to a product manager, where the PM is responsible for the engineer's career growth, compensation, reviews, etc?
As a former engineer turned product manager, I would not advocate such a reporting structure. A PM wouldn't be the best person to help manage an engineer's career growth and everything else. I think it's perfectly fine to be on the same cross-functional team though.
