Conshohocken (Philly suburb), PA
Monetate is hiring - local only, happy to relocate.  We've hired some great people that we met through HN.  We're a SAAS provider of testing, targeting and personalization tools (e.g. content targeting, segmentation, A/B testing).  We've got some grad, high-volume customers and we are growing fast.

Technically, we write lots of client-side JS for our customer-facing product as well as code that runs on our customers' sites.  We're also looking for backend engineers that want to work on large data and web performance. We work in Python, but experience with that is not a prereq.
We have fun problems at scale, great people to work with, and we get instant feedback from our clients on everything we put out! We're having a blast.
