JobScan.co
I like using a tool called Jobscan.co, which is essentially an ATS system for job seekers. It will analyze your resume compared to the job description and give you a match percentage rating.
FlexJobs
FlexJobs is one of the largest job aggregators for remote/flexible work. You can view the jobs, but in order to see the company and apply, you have to sign up for a membership.
