If your only, or primary, experience building games was scripting systems in blueprints (or analogous visual scripting language), you wouldn't get hired as an engineer at most large studios. There is a role for that on those teams: technical designer. The (gameplay) engineer exists to build large systems that might have hooks that allow designers to script/customize the functionality through a visual scripting system. Engineers provide their value lower in the stack.
