the work

What the work is

AI science jobs here pay scientists to set hard questions in their discipline, solve them step by step and spot where an AI's reasoning fails. Across the 205 live jobs on this page that list pay, most pay $36–100/hr, and the median is $65/hr. This is freelance AI-training work, not research scientist jobs building AI.

Words you will see on this page

  • AI trainer (someone paid to write, check or rate the examples AI models learn from)
  • SME (subject-matter expert: someone with a degree, licence or deep experience in a field)
  • Data annotation (labelling data (text, images, audio) so AI can learn from it)
  • Legit Score (our 0–100 rating of how safe a platform is to work for, based on published inputs)

faq

Real questions, short answers

What do scientists do in AI training?

In practice, that means writing problems hard enough to stretch an expert, supplying full worked solutions and grading AI responses for mistakes in method, maths or units.

How much do AI science jobs pay?

Across the 205 live jobs on this page that list pay, most pay $36–100/hr, and the median is $65/hr.

Is this the same as being an AI research scientist?

No. Building models is what AI research scientists do, usually as full-time employees. The roles here are freelance: reviewing and refining model answers within your own discipline.

Do PhD students qualify?

Some take current PhD students; others ask for a completed Master's or PhD. Each listing spells out the level required.
