I think you should also look into and apply to the next Polkadot Blockchain Academy:
As far as I understand, Rust developers are in scarce supply in the whole blockchain ecosystem. Most teams would be willing to interview and hire individuals without specific Polkadot / blockchain experience, but are talented in Rust and able to learn fast.
I would say start applying today, and see what happens while you also follow up with these other things.
EDIT: And on top of all of that, I believe there are a number of specific asks our community would have for the Clippy project, since it doesn’t handle all of our linting perfectly yet. If you’d be interested in helping improve clippy FOR Substrate / Polkadot, I am sure there will be a lot of opportunities there too.
