May want to consider government contracting roles. After spending about 15 years in what has come to be known as "martech" as a web developer, I realized how soulless and unsatisfying the work is. By random chance I was scouted by a small consulting firm that does work for the fed and couldn't be happier. I'm on a project now that helps countless people everyday, has some interesting domain problems, and nobody tries to convince me I'm part of a corporate family with the expectation that I will lie to my dev team about rewarding them for long hours to make some director look good.

I get to touch a lot of things tech wise, as we take on new projects there is the chance to move around when a project finishes or I've done enough time on it to convince them I'm bored and want to try something new.

Sure some firms specialize in defense... but there are many firms that do work with the EPA, NASA, etc.
