Great for developer jobs, clean design, no need to signup
As of Jun 2018 not many non-developer jobs
Remote OK is a job board for remote-focused job opportunities.
I've been applying to different companies for the past few months, and it's definitely the best of class of the remote job boards – Solid design, easy-to-use, great job postings.
However, most of the job postings are developer-focused, so if you're not a developer you may not get immediate value.
