Engineer doesn't "imply calculus and physics". Calculus and physics is not in the dictionary definition of engineer. In fact, the verb form of engineer is exactly what software, network and devops engineers do. When you say it doesn't mean anything, you must mean you, yourself, doesn't know what it means. ;)

I have a graduate degree in engineering, so I at least have some idea of what it means. Are sanitation engineers 'engineers'? They are according to your dictionary definition.

Edit to say: before I went back to school, I was a technician (no degree) who had the job title of 'engineer'. After I went to school I realized how different the worlds of the technician and engineer are. Not to say one is superior. Just very different.
