A lot of major companies offer remote work, but why is that important? Are you using that as a proxy for salary?
How do you find them?
Are you based in the US? weworkremotely.com has worked well for me in the US
Shameless plug here, my side project https://www.mikesremotelist.com finds about 10-20 newly listed remote positions a day, they are not all US based, but the majority are.
