There's nothing to stop you from submitting a story titled "$foo is hiring $language/framework developer!" with a description of the job or linking to the post.

And FWIW, Flurry's analytics library has an option to check for if the app is cracked or not. I haven't used it, but it is there. Its just a matter of turning it on, if you're already using them for analytics.

Anyone can submit such a post, though I don't know if job offers are frowned upon, or even upvoted. Adding a fun puzzle/challenge will probably help though ;)

There are also the monthly "who's hiring" posts.
