Would love to hear more tips. This is me too, and I suspect some of my team members. I've been trying to build in more collaboration into tickets (e.g., an acceptance criteria that is "talk to the rest of the team about the decision you make on X aspect of implementation"), and I'm looking for more.

Those collaborative conversations are so often fruitful in ways I don't expect.

"office hours". a dedicated afternoon where anyone from the company could drop in to a running call and just ask me anything about engineering. bug reports; features; questions; feedback; anything.

building in an extra 30 minutes on team catchup calls just to hang out at the end. usually end up talking about some work stuff, but in a more relaxed/social way.

demo/learning sessions. how to use databricks, how to do X, how X works, this cool thing we built.

I mostly just focus on trying to find one or two people who like pairing and always suggest to do it with them. I always aim to be positive, anti judgemental, understanding, curious, etc. so theyll feel comfortable.

One of my coworkers in an old company set up a "slack" watercooler channel he would always pair in with an explicit invitation that anybody who wanted to drop in could at any time, even if it was just for a chat. That was cool.
