It’s a huge faff, you will get a different answer from every person you ask. They’re used interchangeably, and it just doesn’t matter.

To entertain your prompt. Real world engineers (structural, etc.) aren’t entrusted the title because they “care” about what they build, it’s because they have to be correct, and as such, they follow extremely rigid process and take the time to never be wrong.

That’s not how software works most of the time, and it’s even heavily discouraged in a lot of the industry. We learn from failure, and the consequences of software failing are nil compared to the consequences of a bridge failing.

Again, I don’t really care though what the industry wants to call it, developer or engineer. It doesn’t matter and it’s all made up anyway.
