Levi is best known for creating, directing and producing the television drama BeTipul and for producing In Treatment, HBO's American adaptation of the show. Along with Nir Bergman, he won the Israeli Academy's Best Director award for directing BeTipul's first season. He also wrote for the drama series Shabatot Vehagim and edited several telenovelas.
In February 2013, the American cable channel Showtime ordered a television pilot for a series co-created by Levi. Titled The Affair, the series focused on relationships told from the points of view of both men and women. The first episodes of the series was also co-created by fellow In Treatment writer/producer Sarah Treem, but later on Levi retired from the series writing claiming that the series took a different path than the one he visioned and that Treem "is the best person" to continue to write it on this path.
