Jesse Snyder is a designer who worked on several Call of Duty games from Treyarch and Infinity Ward and the creator of the Nazi Zombies mode. Snyder started working on Call of Duty with Call of Duty: United Offensive and continued to work at Treyarch on Call of Duty 2: Big Red One and Call of Duty 3.
During the development of Call of Duty: World at War, Snyder started working on a cooperative mode as Treyarch was looking for extra content for the game. Working both at the studio as well as on his spare time, and as more developers started working on the mode, it became the "Nazi Zombies" with its first map Nacht Der Untoten. He was also responsible for the Ray Gun Easter Egg featured in the mission Little Resistance. Snyder left Treyarch right after the release of World at War, leaving the studio to continue to work on Zombies.
After several years, Snyder came back to the Call of Duty series and started working at Infinity Ward as Game Designer on Call of Duty: Ghosts and Gameplay Director for the campaign of Call of Duty: Infinite Warfare. Snyder then worked for a year as Campaign Designer on Call of Duty: Modern Warfare, where he was behind the idea of the weapon mounting mechanic for the game, before leaving Infinity Ward.
