Apple is definitely excited about a new mysterious feature that "will truly amaze everyone [...] a new and revolutionary feature for Mac OS X." The extreme hyperbole in their latest job offer is surprising, and it doesn't stop there:
Are you looking to help create something totally new? Something that has never been done before and will truly amaze everyone? Are you excited by the prospect that what you helped create would be used every day by millions of Apple customers? Then come and work on with the Mac OS X software engineering team to help build a new and revolutionary feature for Mac OS X.
We are looking for a senior software engineer to help us create a revolutionary new feature in the very foundations of Mac OS X. We have something truly revolutionary and really exciting in progress and it is going to require your most creative and focused efforts ever.
I was getting excited until I saw the requirements asking for "experience with developing for Internet technologies and services." And then I got even more excited, because maybe this means they are taking cloud integration seriously at last.
