Where do you find your contract US startup jobs? All I see is full time jobs on angel list. Maybe I'm not looking in the right place?

All jobs on AngelList are potentially contract if you're outside the US. Unless they want to set up a subsidiary for you (they won't) or use a global PEO (some do want to do this but most are happy with a direct contract in my experience).

I get lucky on slack sometimes.

They can't do it like they do on the discovery channel
