AI training roles

UK-focused · Independent · Listed pay only

AI training jobs in the UK, with the pay listed up front.

These are remote AI training jobs in the UK — contract and freelance work that helps train and evaluate AI models, including data annotation, rater and evaluator tasks. That is not the same as a salaried job teaching people how to use AI. We list the pay from each public posting, never estimate it, and send you to the platform to apply. Hours are often flexible and the work is usually done from home, but an assessment is typical and work is not guaranteed.

FAQ

AI training jobs in the UK: common questions

What is an AI training job?

It is paid work that helps improve AI models: writing prompts and model answers, grading whether a response is correct, comparing two answers, or reviewing audio, images and search results. Most roles on this site are remote freelance or contract work, found after an application and an assessment.

Can I do AI training jobs from the UK?

Yes, for the roles listed here. We only list postings that name the UK or are open to remote applicants worldwide, and we show where each one says it is open. Some ask for years of UK residency, a UK accent or a degree. Always confirm eligibility on the platform before you apply.

What is an AI tutor job?

“AI tutor” and “AI trainer” are common names for the same kind of work: teaching a model in a subject you know by writing good answers, explaining mistakes and scoring its output. On this site those roles appear under titles such as Generalist Expert, English Language Expert or a subject expert in law, science or finance.

How much do AI training jobs pay?

Pay is set by each platform and is usually in US dollars. Hourly roles listed here range from $14 to $170 an hour on the posting, depending on the field and the expertise needed. Some roles pay per task instead. We show the figure each posting states and never estimate it.

Do I pay tax on AI training work in the UK?

Usually yes. These platforms generally engage people as contractors, so in the UK you are normally treated as self-employed and may need to register for Self Assessment with HMRC. We cannot give tax advice; GOV.UK has the official guidance.

Is TrainAI UK a recruiter?

No. TrainAI UK is an independent listings site. You apply on the platform. Some apply buttons are referral links marked “Ad”, and the platform may pay us a fee if you are hired and do qualifying work. Your pay is not affected.

Are these the same as AI trainer or teaching jobs?

Not on this site. Searches for “AI training jobs UK” often bring up salaried posts teaching AI courses or apprenticeships. The roles here are remote contract work in which you help train or evaluate an AI model — for example by writing prompts, scoring answers, or annotating language and media. Job titles may say AI tutor, AI trainer, evaluator or rater.
