Anthropic is hiring a full-stack engineer for its Reinforcement Learning organization. The person builds the web platforms, backend services, and APIs behind RL environment creation, human data collection, vendor tooling, and training observability, including labeling workflows, QA systems, and evaluation dashboards. The posting asks for Python and a modern web stack (React, TypeScript), end-to-end ownership from database schema to frontend, and comfort turning vague research needs into shipped products. No ML research background is required; Claude writes much of the committed code.
