Anthropic's RL Scaling Science team studies how reinforcement learning behaves as model size, compute and task horizon grow, and turns that into training recipes for frontier models. A research engineer designs and runs large-scale RL experiments, builds benchmarks that make long-horizon progress measurable, and ships validated findings into production training, debugging failures that appear only at scale. The posting asks for empirical RL or large-scale ML training skills, Python and distributed systems experience, and comfort at the research-systems boundary. London-based, hybrid.
