Jon Lech Johansen, known as "DVD Jon" for his notoriety for breaking anti-piracy code on DVDs, has posted on his blog a want ad for a couple of coders interested in working for DoubleTwist Ventures. The company is noteworthy for having reverse engineered Apple's FairPlay digital rights management system.

Johansen, a native of Norway who also works as a software engineer for DoubleTwist, said the company is looking for a reverse engineering specialist to work on its DRM interoperability technology. A minimum of three years of experience is required, and, in a reference to an old computer interrupt code, Johansen quipped, "Your favorite number is 0x90."

In addition, the company wants to hire a "senior code monkey" to work on audio/video products. A minimum of five years experience is needed.

Johansen, 23, is a self-trained software engineer who became well known among techies for his work on DeCSS software, which decodes the content-scrambling system used to enforce DVD licensing on movies. DoubleTwist is working on interoperability technology that would make it possible, for example, to play music bought from Apple's iTunes store on any device. Songs downloaded from iTunes today can only be played directly on the Apple iPod.

Johansen has been critical of Apple's DRM efforts in the past.
