architectural Engineering. A starting electrical engineer with a Masters is around $60-65k in Los Angeles, more in Bay Area. Junior staff cannot be effective remotely; they do not work independently for a few years, and when they hit that mark they need to be helping to mentor the next generation.
Senior engineers can be remotely with only limited loss in productivity, and mid-level can safely be remote a day or two per week. We do have a remote office, as well as one full-time remote employee. It works very well for some things, but going for a job survey on a day's notice is a little hard when you are a thousand miles away.
We can find plenty of people, at salaries we are quite comfortable with. It is important to understand the cost of bringing one employee on board through the first few months of work though. It is rarely less than $50k, and often double or triple that for senior staff.
As for flyover country, grew up there, went to school there, always happy to hire from there. Not especially interested in hiring people living there that can only be productive for 65% of tasks though, even if it is at a 50% salary discount. Too many additional costs that direct salary don't reflect.
