Responsibilities

  • Evals for Conversational Quality: Developing custom evaluation frameworks to measure "conversational success." You'll go beyond basic fact-checking to rigorously assess conversational dynamism, warmth, engagement, and hallucination reduction.
  • Building prompt systems that allow Known to maintain a consistent, empathetic, and uniquely "Known" personality.
