Anthropic's Code RL team is hiring a staff software engineer to build APIs, frameworks, and abstractions for agentic coding environments and reinforcement-learning research. The person will embed with research teams on rotation, improve reliability in evolving research codebases, design safeguards against silent failures, and support production RL runs. The posting asks for deep Python skills, including static typing and concurrency; experience designing adopted APIs; comfort in large codebases; and strong communication. Distinctive aspects are the rotational embedding model and responsibility for engineering standards on a new team.
