There is a Stack Exchange staff member with the role "Community Evangelist", as mentioned here:
This person is not part of the Community Management Team, where their role is explained.

I'm still carving out and building out the role. It's similar in scope to what's known as a Technology Evangelist in the industry, but we don't really do "typical" roles here when it comes to community. I do a lot more.
I've served a lot of roles within the company all centered around the community (I'm on my 7th year now). Prior to that, I was an elected Stack Overflow moderator. After serving out my four year demotion to management and regaining the ability to become an individual contributor again, I wanted to get back to a role where I focus mostly on Stack Overflow, and making sure we keep everything that makes it amazing as we head into the future.
Some of the stuff I do:
Eventually this role, like other roles I've had in the past, will probably split into several roles. The duality of focus between keeping up on everything going on with the platform and products, and keeping a really good eye on what the community is doing and outreach initiatives will, sooner than later, become three or more full-time jobs.
This is also not exhaustive, but a pretty good overview. I don't know if "evangelist" is the best word, but it's the closest we could come while still keeping something that stood a shot at being recognized :)
If I'm honest with myself, I'm still pretty much a unicorn yodeler.
