How to move from Manager to IC?

I'm currently a Product Manager with people-manager like responsibilities. This is my second company to have this type of role. Before that I was purely a people manager, and before that a project manager. I have basic coding capabilities but it's been several years since I've done real engineering work.

I am tired of the meetings, of pestering people to get things done, of having surface level knowledge about a lot of different things but not deep knowledge about one particular thing. I want to be able to sit at my desk and build things, not move from meeting to meeting talking about why things aren't being built.

This leads me to think I should move into an IC role, and away from management. Has anyone done this before? How can I do this at my current org (a series B startup where I definitely am not strong enough engineering wise to jump right into coding, but could feasibly do something like technical writing). Or do I need to start over somewhere new? Spend a few months re-learning to code? I'm really lost but I know I need to make a change, soon.
