Return Path is an enterprise-level, email marketing analytics application (think Google Analytics for email deliverability and brand security for enterprise customers - Groupon, Dillards, American Express).
We have a solid UX team, working a suite of about nine products, and we have started to move us over to a responsive UI and live style guide on Bootstrap and to extend our user research breadth and depth. The Product and UX teams work in tandem and are using the Lean Canvas and Validation Board methodologies.
Return Path as a company has a remarkable culture - none I've ever experiences, nor expect to find again easily. #3 best place to work in CO last year and #11 nationally.
For sure worth a chat to see if it's a "fit overall and all around".
