Outside of tech, there are plenty of pretty mundane businesses that do lots of social good. In tech this is harder mostly because everything has almost global availability by default. But still, you don't neccesarily have to work at one of the big five to have social impact.

As for finding meaning within, I see this as a cop out. If you extend it to the limit, the most meaningful life is that of doing nothing and enjoying your inner self. It's not the kind of life I'd personally find meaningful.
