Facebook has named Mike Schroepfer as the social network’s new chief technical officer on Friday afternoon.
Until now, Schroepfer has served as vice president of engineering at the Menlo Park, Calif.-based company.
The role of CTO has been vacant at Facebook since the departure of Bret Taylor last June.
Before serving as the VP of engineering for the world's largest social network, Schroepfer filled the same role at Mozilla. While there, he lead global product development for the company's software, including the Firefox browser.
This is also not the first time that Schroepfer has been appointed CTO. He was also CTO (as well as a distinguished engineer) at Sun Microsystems.
Coincidentally, Facebook's headquarters are located at the former Sun campus in Silicon Valley.
We pinged Facebook for comment and will update this post when we hear back.

Mike Schroepfer's new designation as Facebook's CTO reflects the unique and important role he plays across the company.
