I don't mean to be an ass, I just expected more when I read the headline. Applying via pull request or something. This is really just a link to job description, though.
Sounds like an interesting company but from the tone of the job ad it really feels like the current marketing mix is based on dogma. I'm not saying inbound marketing isn't great but outbound marketing should really have a seat at the table as well if you are looking to accelerate growth.
Interesting the aversion to paid marketing. I would definitely be hiring someone that had at least solid Adwords experience and maybe other networks and pushing into that area in a big way, given the funding raised.
