What AI training work is, and who pays for it

AI labs need domain experts to write, review and grade the material their models learn from. A radiologist checks a diagnostic explanation, a tax accountant writes the reasoning behind a filing, a backend engineer builds a test environment an agent has to solve. That work is bought through a handful of specialist marketplaces, it is almost always remote, and it is almost always paid by the hour or by the task.

The problem is that the work is scattered. Each marketplace runs its own board, its own titles and its own pay conventions, so finding the roles that fit you means checking six sites and mentally converting between them. This page collects the listings into one feed with one set of filters, refreshed daily, and links each one straight through to the marketplace that posted it.

1

Find work that matches your expertise

Search by skill, filter by pay, commitment or experience level, and see every marketplace side by side instead of one board at a time.

2

Apply on the marketplace that posted it

Every listing links to the original posting. You apply, onboard and get paid by them directly. Skillora does not sit between you and your earnings.

3

Practise the screen before you take it

Most of these marketplaces screen with a recorded or live interview. Run the same interview with Skillora first and get feedback on your answers.

AI training jobs, answered

What is an AI training job?

It is paid work producing or evaluating the data that AI models learn from. In practice that means writing expert answers in your own field, grading model output against a rubric, building coding or tool environments for an agent to solve, recording speech, or reviewing another contributor’s work. It is contract or task-based rather than salaried, and the marketplaces that buy it recruit for specific domains rather than for general labelling.

How much do AI training jobs pay?

Rates vary far more than in a normal job market because they track scarcity of expertise, not seniority. General contributor work sits in the $15 to $30 per hour range. Specialist domains such as medicine, law, quantitative finance and senior software engineering routinely post between $60 and $150 per hour, and some expert roles go higher. Some work is priced per task instead of hourly, in which case we show the task fee as published rather than inventing an hourly equivalent.

Do I need experience in AI or machine learning?

Usually not. These roles hire for depth in a subject, not for ML skills, because the whole point is to get expertise into the model that the model does not already have. A practising lawyer or a cardiologist is a stronger candidate for a domain role than a generalist who knows how transformers work. Software engineering roles are the exception, since the work itself is writing and reviewing code.

Is AI training work remote?

Almost always. The overwhelming majority of listings in this feed are fully remote and asynchronous, which is why they suit contractors, people between roles and anyone doing this alongside another job. Where a listing states a country restriction we show it on the card, and where it states none we say so plainly rather than claiming it is open worldwide.

Which marketplaces are included?

Mercor, micro1, Alignerr, Outlier, DataAnnotation and Terac. These are the platforms that publish expert AI-training work openly. We refresh the feed once a day and keep listings that have closed accessible, marked as no longer listed, so a link you saved never dies silently.

Does Skillora charge for this?

No. Browsing and applying are free, and you are never asked for an account to see a listing. Where a marketplace runs a referral programme, Skillora may earn a fee if you sign up and work through our link. It costs you nothing, we say so on every listing where it applies, and it has no effect on how listings are ranked. The ranking code has no knowledge of which sources pay.

How do I get hired for one of these roles?

Every marketplace screens before assigning work, most of them with an interview that is recorded or run by an AI interviewer, followed by a paid trial task. The screen is the part most candidates underestimate: it is where you have to explain your reasoning out loud in your own domain. Practising that specific format is the single highest-leverage thing you can do before applying.

Every one of these marketplaces screens you first

The screen is usually a recorded or live interview in your own domain, followed by a paid trial task. Run that interview with Skillora before you take the real one and get feedback on how you explained your reasoning, not just on what you said.
