This author is certainly known in the rationalist-ish ("less wrong", Scott Alexander etc.) community; whether or not they'd consider themselves a member I don't know. Not all rationalist posts are that well written, but there are certainly more I've enjoyed like that.
I think the author might have heard of Seeing Like a State and the idea of legibility through the book review on slatestarcodex, for example.
EDIT: from their about page, "Before this, I was a software engineer first at a few FAANG companies and later at start ups." I guess that counts as another community of sorts?
