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 → data scientist reads 70% ready; the reverse only 54%. Skill overlap is not symmetric, and the direction you travel matters.
Data Scientist → Machine Learning Engineer
Transition estimate: 12–24 mo.
The gap, from machine learning engineer postings: Computer Vision, GCP, Clinical Research, Model Fine-tuning.

Quick answers
Which pays more, data scientist or machine learning engineer?
Machine Learning Engineer, by about $4k a year at the midpoint. Going by postings that state pay, the posted middle band for a data scientist runs $76k–$160k, and for a machine learning engineer it runs $78k–$166k. We only count postings that state a salary, so these are advertised figures rather than estimates.
Are data scientist and machine learning engineer the same job?
Close to it. Their postings ask for largely the same skills, and the difference is mostly emphasis and title. The skills both sets of postings want are Machine Learning, LLMs / Generative AI, Python, Deep Learning, MLOps.
Can a data scientist become a machine learning engineer?
Yes, and a typical data scientist profile already covers 54% of what machine learning engineer postings ask for. Our estimate for the transition is 12–24 mo. The route page lists the exact skills that make up the gap.
Can a machine learning engineer become a data scientist?
In this direction a typical machine learning engineer profile covers 70% of what data scientist postings ask for. Our estimate for the transition is 6–12 mo. It is worth noticing that the two directions are not symmetric: machine learning engineer to data scientist is the easier move (70% against 54%).
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.
