Definitely! Emcien (from mCn - we deal with a lot of combinatoric problems) is focused on analysis of large-scale data by constructing and operating on relationship graphs of tokens within that data. We use Rails pretty heavily for presentation, though our apps have been leaning more and more on Backbone.js, and most of the core science is performed in some C code largely written by one of the founders, O.R. prof Roy Marsten. The business/marketing site is at emcien.com, and the (fairly new) engineering blog is at engineering.emcien.com. Management sadly isn't interested in long-term remote devs yet - we're in Atlanta, GA. It's a great environment though, in the sweet-spot between risky startup and heavy corporate work.
