Pinterest announced two big hires today: Michael Lopp, who will head up engineering at the social-bookmarking site, and Bob Baxley, who joins as head of product design and research.

Lopp was most recently a director at Palantir Technologies, a software company that specializes in data analysis. Before joining Palantir, Lopp spent over eight years as senior engineering manager at Apple. Baxley was most recently senior manager of design and product management at Apple. He was previously the director of design for Apple’s online store, and served in the same position for Yahoo Search.
