Facebook has finally filled its vacant Chief Technology Officer position today, and the job is going to Mike Schroepfer.

Schroepfer has served as VP of engineering at Facebook since August of 2008. Before that, he worked at Mozilla for three years where he also served as VP of engineering.

“Mike Schroepfer’s new designation as Facebook’s CTO reflects the unique and important role he plays across the company,” Facebook said in a statement.

The CTO position had been vacant since last summer, when former tech officer Bret Taylor left Facebook to start his own company. Taylor had joined Facebook in 2009 as the head of platform, having previously helmed FriendFeed.
