AI Career Compass · role
Writes, labels and checks the data that trains and tests AI models. AI tutors, annotators and raters, and subject experts who write and grade model answers.
Limited sample: fewer than 20 postings. We show counts, but no rankings or shares as findings.
One employer has 61% of these postings, so they mostly show what that employer asks for.
Measured AI tutors and data specialists make up 18 of the 1694 AI postings in our tracked sample, about 1%.1
Measured The skills these postings ask for most are training data and human feedback, data analysis and communication, each asked for in 4 of 18.123
Written by an AI analyst (claude-opus-5-5) and checked by code against the numbers it cites.
What these postings say the work involves, counted from their lists of duties. A posting can list several.
Out of these 18 postings. “Asked for” adds required, one of several options, and listed; preferred is counted apart.

Measured Evaluation, meaning testing how well an AI model works, is listed as a preferred skill in 5 of 18 postings.1
Measured Knowledge of large language models, the kind of AI behind chatbots, is listed as a preferred skill in 5 of 18 postings.1
Employers list these as preferred. That they ask does not show that these skills decide who is hired.
The systems these postings expect people to build, run or work within.
Only what the postings state. Most do not say everything, so each number has its own count of postings.
6 of 18 postings state a minimum; the median is 3 years.
5 of 18 postings state a degree; 2 of them accept equivalent experience instead.
1 more posting lists a PhD as preferred.
12 postings are remote. Of these, 11 name where you must live or work from, 0 do not say, and 1 says anywhere.
What employers advertise, grouped only when the ranges are comparable. Not a prediction of what you would earn.
8 of 18 postings (44%) advertise a pay range. Employers that publish ranges may differ from those that do not, and some places require it by law, so these ranges do not describe all pay.
No group of at least 10 comparable pay ranges (same currency, period, pay type, country and employment type).
This is advertised pay, not what anyone earns. We pool ranges only when currency, pay period, pay type, country and employment type are the same, and only with at least 10 of them. Nothing is converted. 8 other ranges could not be pooled (period not stated, several countries, or too few alike).
Advice built from what these 18 postings ask for. Tick what you can already do; we suggest up to three steps and one portfolio project, each with the requirement behind it and a way to show the result.
Measured Our window holds one reading so far, taken on 6 October 2026 when tracking began, and only 3 of the 18 postings were first published in the 30 days before that reading.1
Measured The AI postings we track come only from 46 employers that publish their jobs through public feeds; employers that run their own job systems are not included.1
Measured This role's sample is small and concentrated: 18 postings from 5 employers, and 16 of the 18 come from the three employers with the most postings.123
