I wish there was a jobs board for companies that are somehow vetted for this type of engineering culture.

So many jobs are sold as “we’re pragmatist's” and when you show up there’s 5 devs, 50 repos and most of the work is discussing if x requirement should be a new micro service. The product is usually an web app with 10 entities and and an API.

Suppose it’s keeping people in jobs

There is, it's java/ruby shops. No one wants to use that stuff in current year, so if they're using it anyway, they're pretty likely to be boring tech users.
