Matasano is always hiring application security people, and I'm always happy to talk to systems developers who'd like to do more appsec and software security. We're like the antistartup job: instead of sinking 1-2 years of your time into building a single product built on a single stack, you work with hundreds of firms unbuilding systems running on practically every stack.
http://www.matasano.com/careers/ goes into a lot of detail about our hiring process, which people seem to like.
I'll be out in Mountain View next week if you're interested in what we do and might want coffee.
Special offer: if you're wondering what the day-to-day of our work is and want to learn some interesting things about breaking crypto, mail "sean" at Matasano and Sean will send you a series of cryptographic exercises, 40+ in total, ranging from CS101 stuff through block cipher attacks to number theoretic crypto.
