Burke Libbey has a few talks that are available on YouTube including a presentation at NixCon about the work he is doing at Shopify. I would highly recommend checking them out if you are interested in Nix.
Can you provide more information about setting a build infrastructure in an organization. Particularly how to set up a shared cache so if one user builds something it is available to others?
Yes, we’re hiring! You may have seen the news today that we’re all in on remote now. Send an email to burke.libbey@shopify.com, I’m as good a point of contact as any for Nix stuff.
