'DVD Jon' is hiring

Jon Johansen, the 20-something hacker widely known for helping crack the piracy protections on DVDs several years ago, is hiring people for his latest venture: taking on Apple's digital rights management technologies.

Johansen's DoubleTwist Ventures is looking for a "Reverse Engineering Monkey" and a "Senior Software Monkey." The Norwegian started DoubleTwist to license technology that will make other online music stores work with Apple's iPod device and let iTunes songs play on gadgets other than the iPod.

The first position involves working on DRM interoperability technology and requires cryptography, reverse engineering, AJAX, code disassembly, code protection/obfuscation and software optimization skills, according to Johansen's blog. "Your favorite number is 0x90," he wrote on Wednesday.

The second job is to work on audio and video products and requires experience designing, implementing, debugging and optimizing applications, according to the description on Johansen's blog.
