Remote AI training and data labeling jobs

Evaluate frontier AI responses on grey-area and policy-sensitive topics (misinformation, political persuasion, self-harm, violence, cyber, biosecurity), apply safety rubrics and write structured feedback. 5+ years in trust and safety, journalism, policy, research or security. US, UK and most of Europe. $60–70/hour.

Design adversarial prompts, find jailbreaks and policy failures, and document vulnerabilities in frontier AI models across cyber, biosecurity, fraud, misinformation and political content. Hourly remote contract at $70–84/hour for residents of Europe, the UK and the US; 5+ years' relevant experience required.

The UK posting of Mercor's molecular biology project: design primers, plasmids, gRNAs, mRNA constructs and repair templates as ground truth for a frontier model, and write the rubrics that judge them. PhD strongly preferred, first-author record expected, 20 hours a week. $70–105/hour.

Produce the decks, models and operating-model work you'd build on a normal engagement, alongside experts from two other disciplines, so the outputs can be turned into the tasks and rubrics that train frontier models. $140–200/hour for 40 hours a week from 14 September to 10 October 2026. You must be based in the UK with the right to work there.

Build and document the production pipelines you'd work on during a normal week, alongside experts from two other disciplines, so the outputs can be turned into the tasks and rubrics that train frontier models. $140–200/hour for 40 hours a week from 14 September to 10 October 2026. You must be based in the UK with the right to work there.

Write difficult problems in your own field for a top AI lab's language models. Open to PhDs (or equivalent industry experience) in medicine, statistics, AI/ML, computer science, game development or mechanical and aerospace engineering, living in the US, UK, Canada or Australia. Remote hourly contract at $55–80/hour, paid weekly.
