As someone who always knew I didn't really need to know code for what I wanted to do, I'd posit that a developer comes across as someone who may not be formally trained. Maybe they're a hacker, maybe they know a language or two and dabble. A software engineering is someone who is comfortable at various levels and understanding machine level code in so far as also being comfortable with software patterns.

-shrug-. That's what I feel like in my org at least.
