I realize that I’m late to this party, but if you’re a techie there are a several sites out there that cater to remote job listings (disclaimer/disclosure, the first one is my site):

Remote Jobs: Hiring Programmers and Designers | Remotely Awesome

Remote Jobs for Digital Nomads

Remote Jobs: Design, Programming, Rails, Executive, Marketing, Copywriting, and more.

Jobspresso

You also mentioned Angelist — the job post section of their site now features a “collection” that shows only remote jobs: https://angel.co/job-collections/remote
