Jost, a Harvard alum, joined SNL in 2005 at age 22, and was promoted to head writer in 2012. Some of the sketches he's written recently include the 50 Shades of Grey screen test, the "We Did Stop" government shutdown music video, and the opening sketch with Kerry Washington that criticized the show's lack of black female cast members.
