Contrary to popular belief, in the US there are state/federal government software jobs.
They don’t pay as well as the private sector, but it’s only a few steps down, not “get used to earning 20% as much”.
Is the bullshit rate in many of those jobs incredibly high? Absolutely. But can a talented generalist from the private sector make huge improvements for real people? You bet. So much of government IT is crippled by dated approaches and over-reliance on contractors (and the lack of knowledge of best practices that comes from very few folks transitioning from the private sector—those few steps down in salary are not a road often travelled).
As a result, someone with talent and familiarity with how much better things can be (and a willingness to push on broken rules/processes) can have a huge impact. You’ll have to do a lot of “here is a prototype nobody asked for built in a way nobody here is currently allowed to build it”-type performing in the first year or two, but at the right government agency folks who do that get to deliver massive benefits to real people every day.
There are enough sub components of government (agencies, sub-agencies, state, municipal) that you can easily find work you agree with. It’s frustrating to apply, but truly: once in the door, talented folks can achieve a huge amount.
