Data and ML work for AI
AI Training Jobs for Data Scientists
Measured from 38 distinct advertised rates, across 10 platforms. 6 of the 51 open roles here state no hourly rate; 7 advertise only a maximum ("up to $X/hr"), which is excluded.
AI labs pay data scientists and ML engineers by the hour to grade a model's analyses and ML code, design the benchmarks it is tested on, and write the solution an expert would. 51 roles for data scientists are open right now on 13 platforms, including micro1, AfterQuery and Alignerr. Every role is checked against its platform's job board daily.

Before you apply
This is training and evaluation work for AI models. If you are employed, check your contract's outside-work and IP clauses first, and never use your employer's data, code or credentials in a task. A legitimate platform never charges you to apply.
Pay by specialty
Each specialty's typical pay is measured over its own open roles the way every band on this site is (the 25th percentile of what roles pay (the middle of each advertised range) to the 90th-percentile advertised ceiling), and shown only where at least three distinct rates are posted.
| Specialty | Open roles | Typical pay | Highest rate |
|---|---|---|---|
| Machine learning engineers and researchers | 28 | $70–$150/hr | $400/hr |
| Data scientists | 18 | $60–$270/hr | $350/hr |
| Data analysts and data engineers | 5 | $45–$80/hr | $80/hr |

Frequently asked questions
How much do AI training jobs for data scientists pay?
Across the 38 distinct hourly rates posted for roles for data scientists right now, typical pay runs from $60 to $185 an hour, with a median of $85. The highest posted rate is $400 an hour, at Alignerr. 6 of the 51 open roles for data scientists state no hourly rate, so check each listing.
What experience do these roles ask for?
Most ask for professional experience in data science or ML and strong Python, often with SQL; research roles ask for a master's or PhD or published work, and a few for competition results. Each listing states what it requires and where it is open. Of the 30 open roles for data scientists whose requirements we read, 5 a master's, 10 a bachelor's or a degree and 15 name no degree.
What does a data scientist do in AI training?
You check a model's analyses, statistics and machine learning code, build tasks with answers a script can verify, and audit the work of coding agents on data and ML problems. It is remote, hourly contract work, and many roles start with a coding assessment.
How do platforms check data scientists?
Most platforms start with an assessment in your field before any paid work, and each listing says what it asks for. Of the platforms hiring data scientists now, micro1, Alignerr, Turing, SuperAnnotate (SME) and Mercor run an AI interview (a recorded interview scored by AI) for many roles. micro1, AfterQuery, Alignerr, Turing and SuperAnnotate (SME) check a government photo ID, usually with a selfie, before you are paid. AfterQuery and Turing say they check credentials such as degrees. The section on how each platform checks you quotes each guide with its source.
Are these jobs legitimate?
They are posted by established AI data platforms (micro1, AfterQuery, Alignerr and Turing among them), and each platform's page here covers whether it is legit, how it vets people and how it pays. A legitimate platform never charges you to apply or to get work.
