Looks like plenty more birds are flying Twitter's coop.
Sara Haider, a mobile engineer and technical lead at Twitter for the past four and a half years, announced on Friday that she plans to leave the microblogging company to join Secret, the buzzy anonymous social startup that launched just two months ago.
Haider will assume the role of Android lead for Secret, where she'll be responsible for launching an Android version of the app as soon as possible. (Currently, Secret is only available on iOS devices.) At Twitter, Haider worked to launch the Android version of the company's Vine video app, and for years also worked on the Android app for Twitter proper.
