I'm not an engineer, so I don't like referring to myself as one. Even most actual engineers who are "software engineers" don't do anything remotely engineering-y.

Programmer or coder etc to me sound too mechanical, as if literally (badabish) writing code is all I do, which isn't true.

So software developer feels more accurate to me.

But at the end of the day I'll take whatever title will pay the most for the most enjoyable work.
