It's a really unusual setup, so I'd be surprised if there were a reference book on it. What makes it work is the engineering culture there, and not so much the tech stack recipe. The unusual features are that you're expected to prioritize helping out a fellow engineer if they ask for help, even from another team; and there is a culture of being blunt with criticism. You're expected to be straightforward. I've heard a junior engineer bluntly tell the team that we're wasting time in a meeting, and everyone agreed, apologized and got back on track. This is on top of the standard cultural best practices of no-blame, psychological safety, team autonomy, mandatory work-life balance, etc. The downside is a long onboarding process.
