Might I suggest the civic tech sector as a place where coders (and designers and product managers) can find morally satisfying work? You can work directly for government in organizations like the US Digital Service and 18F that bring the lean startup model into the public sector or join purpose-driven private companies like Nava and Ad Hoc that contract on government project spaces like healthcare using modern development practices. And there's lots of charitable and volunteer opportunities at well.
