Help us build open-source software for education: http://code.instructure.com/
We're hiring for a range of engineering roles. See here for the list of open positions: https://jobs.lever.co/instructure?lever-via=IQ-V_FRhae&team=...
Our main stack is Ruby on Rails + React, but we also work with Go, Clojure, Node and other technologies. We have plenty of hard engineering problems for you to sink your teeth into, and endless opportunities to learn!
Our culture is engineering-driven and very work-from-home-friendly (although we are not hiring 100% remote at present).
Great benefits (including unlimited vacation) and competitive salary.
Feel free to email me at okhan(at)instructure(dot)com if you have any questions (I am an engineer not a recruiter).
