As a data point for anyone curious, they're US based ("Midtown West in New York City") and their careers page mentions the roles are all in-office ones.
They opened/are-opening a northern virginia office, according to their HN posts.
But yeah, as much as I would love to work with them, I have zero desire to ever move out of the southeastern US and especially back to NY. The nature of what they do does kind of require in-office work though.
Ah well. ;)
