Steam

Zachtronics games are usually pretty good. Depending on how comfortable you are with coding etc. some of them are more "overtly programming-y" than others, so could be a better or worse fit.

TIS-100, Shenzhen IO, Exapunks all use (stylized) "assembly" languages.

SpaceChem, Magnum Opus and similar games are more drag and drop.

TIS-100 is meant to evoke sitting around hacking at weird, old hardware and has a whole story to it. It gets hard. I've spent less time on Shenzhen but it is basically the same gist - except now you're an electronics designer, and the language works somewhat differently. Exapunks is "hacking". Most games tend to feature the same kind of scoring allowing you to optimize your solution for speed/cost/space etc

Also a lot of them seem like Factorio clones. It's not on sale (never is) but it's reasonably priced and a very decent game with cool devs.
