Depends on what you see as useful. I feel like most of the dev (and other) jobs out there are just similar variations on how to extract value from someone. Maybe you write the code for Amazon's website - so what? So people can spend money on stuff they don't really need? The point is, nobody here can tell you where to find a 'useful' job, or even what that might be to you.
