Strong Python; version control, tests, CI, reproducible eval harnesses; retrieval and context engineering (e.g., embeddings and vector search with pgvector or Pinecone, RAG, GraphRAG, cache-augmented generation / CAG, agentic RAG, recursive language models / RLM). With a vision for St. Jude to become a global leader in applying data science to biological discovery, the ODS is creating a seamless ecosystem where experimental, clinical, and data scientists collaborate to accelerate discoveries, support scientific initiatives, and advance the understanding and treatment of pediatric catastrophic diseases.
