TBH, as a hiring manager outside of a FAANG, "mid-career parents who want to work remotely" is really the sweet spot for me.
I can't offer enough compensation to compete with FAANGs for new graduates of elite universities, so I have to look at lower tier institutions. That's not to say they're bad or anything... I and many of my best employees dropped out of state schools. But generally, the ceiling is lower, and identifying a new graduate's value is really hard.
And because I'm at a tech company which is not in a super exciting tech hub, I have to be exceptionally remote friendly to land good candidates.
But the thing is: there are tons of employees out there who are smart, get things done, and want to clock out for the day with enough time to cook dinner and play with their kids. We've even hired a few ex-Amazon/Googler's who left because the pay was great but they wanted to have a family.
I selfishly find myself hoping that remote work isn't embraced by those places, or else I'll lose my hiring edge.
You may have a business idea there.
