We're a 13-person team in LA, building a photography marketplace for Instagram photographers! I'll refrain from posting the whole job description, but we're using Ruby on Rails and JavaScript. We're really looking for a SENIOR, server-side developer with good Rails experience right now. We'd consider doing an H1B transfer for the right person.
