Social bulletin board Pinterest is on a roll: After raising a massive $200 million round less than a month ago, it just snagged itself two seasoned veterans to beef up its search and discovery department. Michael Lopp, a former director at Palentir and Apple veteran, is joining as the head of engineering. Bob Baxley, the former director of design for Apple’s online store, is joining as the head of product design and research. Lopp and Baxley actually worked together on certain projects at Apple, including the online store. “As we build a visual discovery engine, we’re thrilled to announce the addition of two industry leaders to the growing Pinterest team. As Head of Engineering, Michael Lopp will lead the technical team behind Pinterest focused on product development and scaling an infrastructure with 30B+ Pins,” the company said in an official statement.
