Yep, factory techs just need a brain and can be trained up to it.

Actual semiconductor design work doesn't happen at said factories. There's also not that much shortage in that space because colleges pump out plenty of EEs with semiconductor focus with Masters and PhDs. They can also struggle to find jobs because well, it's such a niche industry that anyone doing semiconductor design isn't going to leave their job for a non-semiconductor job easily and there's been a lot of industry consolidation in the semiconductor space. The electrical space is quite mature compared to decades ago.
