this is a great summary, and pretty much exactly reflects my role. My job is to help other engineers in our org be as productive as possible. That always means trying to include other people in what I'm doing from a mentor/career-development perspective, but otherwise follows your % splits pretty well.

The bits that people don't talk about frequently are things like "what do you actually do in the 20% of the time you are coding?" It's usually things like performance analyses and optimizations, solving misc tech debt that I have the flexibility to work on since my time isn't allocated to project teams/squads, architecture and PoC work for new capabilities we think we will need, and honestly sometimes its just picking up a couple super low level tasks anyone could do because keeping team members focused on other things is what's most important.

At least in my org the common theme is almost always "there's a hard problem over there, go help them fix it'.
