According to Bloomberg‘s Adam Satariano, Richard Williamson has joined Facebook. We’ve independently heard the same. Williamson is a former iOS executive from Apple who was reportedly terminated over Apple Maps. Williamson ran Apple’s iOS 6 Maps team and also worked on Siri features.

Facebook’s hire of Williamson is notable as the social network reportedly has hired several former Apple engineers to work on various projects, including the Facebook Home software and various other mobile applications. Williamson’s hire marks one of the more high-profile hires of former Apple employees.

Following up on this morning’s news that Loren Brichter is working with Facebook some capacity, Bloomberg also notes that the company has actually hired the Letterpress developer and former Apple employee as a consultant.
