It's a "turtles all the way down" issue, though.

Software architects do the macro design, but they need to do that from an understanding of how it will be implemented, and the various lower level tradeoffs like consideration of the memory constraints of the target platforms.

In order to implement that design the non-architect programmers need to micro-design their bits that they build, too. And those smaller bits also often need abstractions/mini-architectures that aren't part of the macro architecture.
