Backend and systems work is judgement about correctness at scale. AI systems need engineers who can review how a model reasons in Go, Rust, C++ and C#.
This isn’t advisory work and it isn’t labelling. You’re reviewing real engineering work and explaining your judgement clearly enough that an AI can learn from it — paid for your expertise, by the hour.
Applied Clinical Judgement connects qualified people to vetted platforms, and Sean Key personally vouches for those he refers. We’re paid a referral fee by the platform on a successful placement — never by you. The roles below are live today.

No live roles match your search.
AI training work is organised by profession, task and software — not by topic or sector. Try your field (for example “nursing” or “Python”), clear the filters, or browse the categories further down the page. The always-open talent pools below are a good place to start.
What the work looks like
Reviewing the model's work
Read what an AI produced in your field and judge whether the reasoning holds — mark where it went wrong.
Setting hard problems
Write the realistic, demanding tasks that separate competent work from confident-but-wrong.
Judging AI answers
Compare two AI outputs and say which is stronger, and why — your written reasoning is what the model learns from.
Common questions
How much does it pay?
Hourly and contractor-based, varying with seniority and role. Every role card shows its pay band. You invoice as an independent contractor and choose your hours.
Can I do this alongside my current job?
Yes — the work is flexible and part-time by design. Check your employer's policy on outside work first; ACJ can't advise on that.
