In my experience as the carrier of a developer progresses, it is getting less about coding, and more about other tasks. The difference is probably the strongest between a senior vs principal/staff software engineer. In the places I worked principal/staff engineers are looking after the overall design and architecture, negotiating with teams developing other components, helping management with planning, looking after the progress of other devs especially new joiners, etc, etc. I'd say it's about 15% coding at that level and 85% everything else.
