That would be a rather lengthy list, as devs are needed in most industries. But here are a handful (not an exhaustive list) that exist in my area: trucking, railroads, banking, major retailers and wholesalers, hospitals. I'm not talking about bean-counting software here, either.

The single best software dev job I ever had was not working for a software house. It was working in a neurscience lab on applications ranging from software that ran custom experimental equipment all the way through writing software that emulated biological neural networks.
