Description

  • Own machine learning projects from exploration through production deployment and ongoing iteration.
  • Design reliable agentic LLM workflows using tool calling, retrieval, and orchestration for clinical use cases.
  • Build evaluation datasets, offline and online evaluation harnesses, LLM-as-judge pipelines, human-review processes, and regression tests.
  • Improve model quality through prompting, retrieval, distillation, and fine-tuning based on evidence.
  • Work across data preparation, model adaptation, serving, monitoring, and production feedback loops.
  • Partner with Product, Clinical, and Engineering teams to translate clinical needs into technical decisions and identify tradeoffs.
  • Review code, share technical learnings, and mentor earlier-career engineers.
