TrialPay (offer-based payments) in Mountain View, CA is looking for full-time software engineers.
And we just got some pretty good press: <a href="http://techcrunch.com/2012/01/31/trialpay-40-million-visa-greylock/" >http://techcrunch.com/2012/01/31/trialpay-40-million-visa-gr...</a>
Some of the shiny, new things we're working on this year include managing huge volumes of data (~we're now getting 50 million unique visits a day), creating mobile apps for multiple platforms, and improving the huge constraint optimization problem at the heart of our business model (which offers we should show to which users).
So, if you're a great programmer and are excited about working on these kinds of things, please email me: aline at trialpay dot com
