If you expand your career scope to hardware and embedded software, your odds of having to be at a facility, or some customer site, and thus be by other people, rise substantially. I've had a number of jobs where it'd be quite impractical to be remote. e.g. actually building equipment in labs and installing it in machines, aircraft, etc. There are tons of examples. The obvious downside is that the options need to be near your home, or you move. Hence the various "hubs" that pop up for various expertise (SV obviously, but e.g. if you like aviation, Wichita is a good choice)
