As the company grows a certain proportion of new engineers - by law of averages - will be self motivated to seek out and understand how things work, what makes the company tick and how people go about getting things done. You want to make it as easy as possible for them to acquire this knowledge - for they will be standard bearers in carrying the culture forward to the next generation. Record videos and documetns from greybeards and leaders on war stories, architecture, general rules for making decisions and really any other topic that is germane to how culture is defined.

Circumscribed of course as my opinion only, and what I've seen in my career.
