Prompt Engineer
The overlap, measured
Skills that appear in both occupations’ posting demand. This is the shared core; everything else on each side is the difference.
Switching, both directions
The asymmetry is the finding: machine learning engineer → prompt engineer reads 65% ready; the reverse only 18%. Skill overlap is not symmetric, and the direction you travel matters.

Quick answers
Which pays more, machine learning engineer or prompt engineer?
Posted mid-bands from each occupation's own corpus: Machine Learning Engineer $98k–$164k, Prompt Engineer $78k–$113k. At the midpoint that favors the machine learning engineer by about $35k a year. Only postings that state pay are counted.
Are machine learning engineer and prompt engineer the same job?
Close: the skill sets largely overlap in live postings, and the difference is mostly emphasis and title. Skills both sets of postings ask for: LLMs / Generative AI, Python, LangChain / Agents, RAG / Vector Search, REST APIs.
Can a machine learning engineer become a prompt engineer?
Skill readiness is 65 percent: that share of what prompt engineer postings demand, a typical machine learning engineer profile already covers. Estimated transition: 9–16 mo.
Can a prompt engineer become a machine learning engineer?
Skill readiness is 18 percent in this direction. Estimated transition: 12–24 mo. The asymmetry is the finding: machine learning engineer to prompt engineer is the easier direction (65% vs 18%).
Method: each occupation’s salary band is the posted 25th–75th percentile from its own corpus; readiness is coverage of the destination’s posting-skill weight; shared skills are read from the overlap waterfall. Pairs sharing too few skills are not scored in that direction. Refreshed with the nightly scrape.
