What's the difference between a Software Engineer and a Software Developer?
It's also a way to tell if someone works at a BigCo. "Software Engineer" seems to be the standard HR-compliant title.
You may laugh but a few years ago my Father was then the technical director of a small Electrical Engineering company (spun off from Eaton) told me that a junior engineer could not correctly calulate the thinkness of cables for a particular load.
Back when I was fresh out of uni and doing a junior EE position, I had a design engineer rate an electrolytic for the wrong voltage in a switch mode supply. When raised, the design engineer informed me that he didn't make mistakes and that I should go and build a prototype of the circuit without question. My condition was that only if he powered it up, which he did and promptly spend half an hour removing bits of capacitor fluff off everything...
The result was eventually that we just bought COTS switch mode supplies and the design engineer removed head from butthole.
