Sorry for the super delayed reply, didn't expect questions/comments, so just checking this a week later! It's not strictly ruby if you're comfortable adopting another language/framework and are otherwise a great fit for the role.

No worries! HN does not have the best notifications for responses. Similarly, I'm responding fairly late(funny how that happens).

I see you guys have closed off candidates in your job posting. You all do seem like a lovely crowd. I myself am a bit too junior(though not inexperienced) to be a founding/senior member(I read the job title incorrectly the first time), but if you guys end up opening another position, I would definitely love to apply.
