Anthropic's Domain Scaling team seeks a research engineer to improve Claude's performance on real-world knowledge work in finance, healthcare and legal. The role blends applied research and data sourcing: owning vertical data strategy, designing reinforcement-learning environments and reward signals, managing data vendors, building QA to catch reward hacking, and running generalization experiments. The posting asks for experience fine-tuning large language models, reinforcement learning or reward design, LLM training-data curation, evaluation design, and technical vendor management. It is distinctive for its end-to-end mix of research and hands-on dataset work.
