Hired does have companies hiring remote engineers on the platform — so definitely signup & ask your talent advocate for help matching to the right roles.
I've been meaning to write up a roundup of companies with entirely remote teams (technical or all-company) — but in the absence of that, I know Toptal, Buffer, Dribbble, Invision, Zapier, and Github all have remote (or partially remote) technical teams.
Hired (hired.com) does two things that might be close to what you're looking for, if not providing the entire solution:
— We hide candidate profiles from their current employers (and others, upon request)
— We also have a feature for employers called the 'bias elimination tool' which anonymizes candidate names and photos when companies are viewing candidate profiles (more here: https://hired.com/blog/highlights/howhiredcanhelpremoveuncon...)
