For any of the hot tech $115k is actually about $5k low. The author did state ROR which would put him in the hot tech camp and that would be the going rate for that market. I just passed on a w2 position with a pre-IPO company that was $140k. $115 is actually a bargain rate for a senior developer.

I think 115K for a quality, senior engineer is not unreasonable (even for a remote job). I received an offer for a pure-telecommute job (which I declined) for slightly above that figure a month ago.

115k is unreasonably low in the current market.

Apparently he didn't put the salary in the initial email, so, that point is meaningless.

why? That's a pretty basic level salary for a senior developer.
