As an engineer, I like Figma because it provides a nice platform to review designs and add feedback (though I often get lost in it due to its infinitely large canvas and how there feels like there's absolutely no organization whatsoever).

However, every time I've tried to create anything in it, I am quickly confused and overwhelmed.

I don't mind designers who don't touch code - in fact I prefer it. So long as they are receptive to feedback on their designs.
