In January, we shared a tweet from Twitter Principal Designer Josh Brewer calling for “a few good men & women” to join the design team.

Twitter’s design department continues to expand – but will do so without Brewer at its helm. After three years with the company, he’s taking off.

Brewer made the announcement, via Twitter naturally, yesterday late afternoon:

His departure is coupled with that of two other high-profile Twitter employees: Twitter platform director Ryan Sarver and TweetDeck founder Iain Dodsworth.
