The Figma team has a great ladder. I think it’s published on their community Figjam.

Yes, I've seen that one and I like it as well. I'll probably do something similar, but with an IC track and leadership track.

What do you wanna do? Create your own? My faves are Intercom, Gitlab and Gov.uk

Definitely not trying to create my own. If anything, maybe a simplified version of someone else's. These are great suggestions, I'll check them out!
