Ask HN: Experience hiring a Knowledge Architect (or similar)?

How does your organisation manage knowledge and its flow in your company? I'm picturing systems like Slack and Notion (and heck, ZenDesk and Jira et al). As you've grown and perhaps gone fully remote, how have you scaled these systems and the processes on top of them? Have you made or considered full time hires to implement and share best practices, or have teams been able to manage and effectively share their knowledge themselves?

I don't really know what job title is common here, but I'd love to hear if you either _do_ this sort of work or have hired someone to do it.
