Part of your growth may come from realizing that management is quite different form senior engineering roles. You’ll need to learn how to manage a team, and let them do the coding you might be eager to jump in and complete.

Directly answering your question: I’m a member of a peer exchange group (https://www.devcolor.org/). My group meets monthly to discuss our challenges and successes, and learn from each others’ experiences. Perhaps this is something you can explore joining, or starting.

Note that you’re never really on top, and you can always learn more.
