  • Evaluate LLM performance on real support conversations and tune prompts/pipelines
  • Build evaluation harnesses and regression suites to track model quality over time
  • Research and prototype new agent reasoning patterns

What we're looking for

  • 3+ years hands-on experience with large language models in production
  • Deep understanding of prompt engineering, RAG, and tool-use patterns
  • Strong Python and TypeScript skills
  • Experience evaluating and fine-tuning model outputs

Nice to have

  • Familiarity with Convex Agent or similar orchestration frameworks
  • Prior work on customer support or conversational AI
  • Experience with multi-modal models
