The problem with this is, with some marginal effort you could get vastly more money and interesting problems. Accepting a low salary out of some misguided notion that money isn't important to you is silly. Money gives you options you would not otherwise have - a great salary combined with thrift can facilitate an unusual amount of career flexibility. At the very least, you can donate the money you don't need to GiveWell and save a few lives.
It has been my experience that certain problem sets are only addressed by a couple of companies at a time. Sometimes you have to see beyond the culture and pick the problem.
It has also been my experience that a low salary is indicative of a very boring company and set of problems. A very high salary is also indicative of a very boring company and a set of problems that may stem from culture...i.e. poor testing, etc.
...somewhere in the mid to upper end of salary lies very interesting problems. I just don't make my decision based solely on salary.
