• Diagnose quality gaps. When accuracy drops, trace whether it's retrieval, ranking, prompting, or something else causing the issue.
• Experiment with different models and agent configurations, using data to guide decisions.
• Prototype and validate improvements to our RAG pipeline — chunking strategies, retrieval methods, re-ranking approaches.
• Analyze how our customers are using our AI features to help us identify improvements or new areas for development.
• Work closely with other engineers to give them confidence that their changes improve quality.
• Help us stay up-to-date with the cutting-edge AI research, techniques, and tools.
