Hiring RoR engineers has always been a conundrum. In the early days when the language was heating up it was hard to find good rails developers.
Then for a brief period (it felt like the market was finally starting to balance out. Just as quickly the preferred stacks started to shift to Python and others and rails developers started to move on quickly. So we are right back where we are started.
That said, PeopleOps has been here for the whole ride, and we have our EngineYard & Hashrocket swag to prove it :)
