Isn't this why companies have employees with different levels of experience?

Need a bog standard app to stream audio files? Give it to the person you hired right out of college, or maybe even the summer intern. She's never built something like this before, so to her it will be a challenging novel problem. A (somewhat) more experienced developer may need to provide initial guidance and review code, but that's a comparatively minor time investment, and besides, the act of mentoring someone else should keep it interesting.
