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 annotator reads 45% ready; the reverse only 13%. Skill overlap is not symmetric, and the direction you travel matters.
Data Annotator → Machine Learning Engineer
The gap, from machine learning engineer postings: Deep Learning, MLOps, LangChain / Agents, ETL.
Machine Learning Engineer → Data Annotator
Transition estimate: 12–24 mo.
The gap, from data annotator postings: Clinical Research, Translation, QA / Testing, Writing & Editing.

Quick answers
Which pays more, data annotator or machine learning engineer?
Posted mid-bands from each occupation's own corpus: Data Annotator $18k–$69k, Machine Learning Engineer $85k–$153k. At the midpoint that favors the machine learning engineer by about $75k a year. Only postings that state pay are counted.
Are data annotator and machine learning engineer the same job?
Related but distinct: postings share a real core and then diverge. Skills both sets of postings ask for: LLMs / Generative AI, Python, Data Analysis, Machine Learning, Computer Vision.
Can a data annotator become a machine learning engineer?
Skill readiness is 13 percent: that share of what machine learning engineer postings demand, a typical data annotator profile already covers.
Can a machine learning engineer become a data annotator?
Skill readiness is 45 percent in this direction. Estimated transition: 12–24 mo. The asymmetry is the finding: machine learning engineer to data annotator is the easier direction (45% vs 13%).
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.
