There are companies like the one I work for that are willing to hire experienced engineers and then train them on their chosen technical stack. The job engineering descriptions on the Rover.com career page include "Rover’s web app is written in Python and built on the Django framework. Nevertheless, we are willing to train people in Python and Django, so first and foremost are looking for good engineers who are eager to learn."

I think there's another aspect...which is that there is the job and the tools to do the job. The framework is the tools...the job is, in Rover's case, building a web site.
