Remote AI training and data labeling jobs

Build, tune and evaluate ML models in Python with MongoDB-backed data pipelines for a customer AI training project, and document every experiment. Remote contractor, $80–140/hour, 35 openings. scikit-learn, TensorFlow or PyTorch plus hands-on MongoDB is the core stack.

Technical experts audit the tasks used to train and evaluate AI systems, checking each is accurate, realistic, solvable, reproducible and properly tested. You are matched to one of eight specialties, from GPU kernels and Kubernetes to CVE security and SWE-Bench, and take an assessment in it. $60/hour, remote contractor.

Evaluate AI-generated code for correctness and design, write hard coding problems with reference solutions and test cases, and review how a model reasons about architecture, debugging and system design. Asks for a year at a top technology company and a base in an English-speaking country. Remote contractor work at the top of this board's pay range.

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.

Build reinforcement learning environments that test whether an AI model can fix bugs, add features, refactor code and tune performance in real repositories, then write the golden reference solution it is graded against. Public open-source contributions are the requirement, not AI experience. Remote contractor work, roughly 15 hours a week.

Stress-test autonomous coding agents: review the code they write, find the edge cases where they break down, and build the rubrics and harnesses used to score them. Task-based, fully remote, 10–40 hours a week at your own pace.

Design the coding benchmarks that decide whether a frontier AI model can actually reason, debug and ship production code, and build the data pipelines behind those evaluations. A three-month remote hourly contract, full-time availability preferred.

Build and maintain the backend services, APIs and data pipelines behind AI training, evaluation and deployment. A fully remote hourly contract at 20–40 hours a week, aimed at engineers with five or more years of production experience.

Build reinforcement learning environments that test whether an AI agent can fix bugs, implement features, refactor and optimise code while discovering and reasoning over information from real MCP servers. You design the reproducible environment, the deterministic verification and the golden reference solution. Remote contractor work, roughly 15 hours a week, hours of your choosing.
