Responsibilities

  • Design, build, and ship production ML systems powering autonomous underwriting decisions
  • Create feedback loops that convert underwriter behavior into training signals and ongoing model improvement
  • Develop confidence scoring and evaluation frameworks to determine when the system should increase autonomy or defer to humans
  • Build reliable, auditable, and improvable LLM-based agentic workflows across the underwriting lifecycle
  • Work directly with underwriters to extract domain knowledge, validate outputs, and expand the system’s operating domain
  • Contribute to observability, monitoring, and guardrail infrastructure for safe AI underwriting

  • Production experience with LLMs, including prompt engineering, structured outputs, tool use, evaluation, and cost and latency tradeoffs
  • Experience building reliable models with limited labeled data using synthetic data generation, data augmentation, or similar techniques
  • Strong evaluation judgment and ability to define measurable improvement criteria
  • Comfort working autonomously in ambiguous, high-ownership environments
