Blizzard is looking to fill three different positions to work on an unnamed MMO at the developer’s Irvine, Calif.-based studio.

The positions are lead engine programmer, lead tools programmer and lead technical artist.

Outside of the postings, details are extremely scarce, as Blizzard is not offering further comment about the project.

Blizzard’s VP of game design Rob Pardo recently told Next-Gen that the developer is hard at work on new projects.

“We have other PC projects in development and we’re already working on new stuff for World of Warcraft, like another expansion,” Pardo said. “We’ve mentioned in the past that we’d love to get a boxed expansion out every year but it’s more important to deliver really high quality content to our fans. If we can do that every year that’d be great but we’re not going to do that at the expense of the experience.”

There is speculation that one of those new Blizzard projects is StarCraft 2, as the developer has said it is making a product announcement at its World Wide Invitational in StarCraft-loving Seoul, South Korea on May 19.
