Jens Peder "Jeb" Bergensten is a Swedish video game developer employed at Mojang. He is the lead developer of Minecraft as well as its mobile counterpart, Minecraft: Pocket Edition. He became lead developer of the computer edition on December 1, 2011, taking Markus "Notch" Persson's role after he decided to step down, and later took on the position of lead developer for the Pocket Edition on December 12, 2012.
At the age of 11 years old, Bergensten started coding and programming games using the Turbo Pascal and BASIC programming languages. He created mods and maps for Quake III Arena by the time he was 21. He was eventually employed at Korkeken Interactive Studio (later becoming Oblivion Entertainment after going bankrupt), where he was a Java and C++ programmer. Bergensten was leader of the development team for Whispers in Ankarra, but discontinued it after development began to drift apart from what the team had originally envisioned the game to be.
Bergensten left his job at Oblivion Entertainment to move to Malmö, Sweden in 2008 and went on to earn a master's degree in computer science. Around that time he created an indie game development company with Pontus Hammarber and Daniel Brynolf, known as Oxeye Game Studio, developing Harvest: Massive Encounter, and Cobalt. He also had a job at Planeto, an online knowledge community, until November 24, 2010.
Bergensten was hired onto the Mojang team in November 2010, where he was at first a back-end developer for Scrolls, but later gained an interest in Minecraft's development, where he assisted Markus Persson in coding features such as wolves, redstone repeaters, pistons, and various structures generated in each game world. Bergensten and other Mojang staff developed Catacomb Snatch in only 60 hours in 2012 during the Humble Bundle Mojam event, where they distributed money donated to four different charities: the American Red Cross, charity: water, Child's Play, and the Electronic Frontier Foundation.
