Writing prompts and engineering together = prompt engineer. The engineering depends on the prompt and the prompt depends on the engineering. Just like an ML engineer, or a QA engineer, or [anything] engineer. How specific the job title gets really depends on hiring criteria and daily job function.

Otherwise, the job title would be "prompt writer".

Your point is what, that existing engineering titles cover this effort? Sure, you can just call all of it software engineering, but sometimes it's useful to be more specific. The LLMs are so powerful now that this new, more specific title makes sense to me, and clearly those using this new title. We'll see how it pans out over the next few years.

The engineering doesn't depend on the prompt. If you can't build without the LLM you're not an engineer.

This is demonstrably false for many use cases. For one broad example, LLMs have shown incredible performance on many NLU and NLP tasks, that are not currently possible using other techniques.
