The Palo Alto, Calif.-based sequence storage and analysis firm DNAnexus is using an unusual employee referral program to recruit new software engineers. Through August 31, the company is soliciting referrals for candidates to build up its engineering team. "If you refer us a software engineer and we hire them, you'll get $20,000 and your full genome sequenced," DNAnexus says, adding that "if multiple people refer the same person, only the first referral counts." Of course, there are some stipulations.
