According to reports, Facebook has quietly hired Richard Williamson, who led the ill-fated Apple Maps effort and was fired last November, and Loren Brichter, designer of the original Twitter iPhone application and word-puzzle game Letterpress.

Bloomberg reported that Williamson joined Facebook earlier this month as a manager within its mobile software group, and Mashable added that Williamson’s LinkedIn profile now lists his title as director of engineering with Facebook.

And The Next Web reported that Facebook Product Designer Mike Matas sent a tweet Tuesday announcing the hire of Brichter, reading:

Really excited to have @lorenb helping my team out at Facebook.

Prior to working with Twitter, Brichter created Tweetie for Mac, which he eventually crafted into the Twitter apps for the Mac and iPhone, according to The Next Web.
