I don't know about processes or mindset; I think it's mostly a matter of hiring real Engineers and letting them do real Engineering on your backend. That's a cultural problem, though, on an organizational level: if you run everything in the "20-somethings burning midnight oil to ship" mode, the experienced Engineers don't want to join you. You'd have to shift your culture into one that has room for them (like e.g. Facebook is continuing to attempt to do with the Engineers from Whatsapp.)
