I like to remind largely junior engineers I work with that we're basically Dell. We're system integrators. We take the bits that other people have made and glue them together in a fancy box. If they start doing computer science they need to stop for a second and ask themselves if they're really sure they should be doing computer science in case someone else already has and they can just leverage what they've done.

The focus for me is really building appropriate abstractions over the work I do so that people can focus on improving only the vertical slice they need to.
