You can't just go anywhere and work. You need to hold a work VISA. If you go anywhere in Europe, you're not allowed to stay longer than 90 days in a 180 day period. Every country will require a work VISA and they are not that easy to get. Expect a huge pay cut compared to a US salary.

I suppose if you're self employed you can go anywhere but there are legal limits to the time you are allowed to stay in almost every country. This is not a planet where one can just work and live where ever they want.

Want to do something wild, Ukraine's International Legion is looking for people. It seems to meet your requirements of culture, outdoors, tech, and /or ease of visas.
