AngelList works almost as you'd expect from a dating app. You can click "Interested" in a position or company. If the company does the same with you, an introduction email will be sent to both parties. This helps save time applying for jobs as you know who's interested.
Currently there are a couple hundred remote jobs listed (in total, not specific to front end). While that is still a good number to look through, it's nothing compared to many of the remote-specific job boards.
