I like Spotify's organizational structure. In addition to product groups and tribes, there are cross concern practices that anyone can join. For example: UX, TDD, and SRE can be engineering disciplines that bring their voice across product groups. And I totally agree, reliability engineering starts in the beginning with dev. I see this mindset happen more with Elixir/Erlanf devs than Rails devs. (I do both). The whole focus on "developer experience" tends to bias concerns for reliability engineering as if that will magically go away.
