  • Working knowledge of statistical modeling, machine learning algorithms, experimental design, and model evaluation techniques.
  • Applied understanding of exploratory data analysis, data wrangling, feature development, data visualization, model production concepts, and insight generation.
  • Familiarity with generative AI, LLMs, prompt engineering, embeddings, RAG, or AI evaluation approaches.
  • Ability to analyze structured and unstructured data and translate findings into business recommendations.
  • Strong communication skills with the ability to explain analytical concepts to technical and non-technical stakeholders.

Preferred Qualifications:

  • Experience with Azure, Databricks, Git, MLflow, or cloud-based analytics environments.
  • Familiarity with vector databases, semantic search, embeddings, or knowledge retrieval methods.
  • Exposure to LangChain, LangGraph, Semantic Kernel, or similar agentic AI frameworks.
  • Experience supporting experimentation, proof-of-concepts, MVPs, or AI product development.
  • Understanding of Responsible AI, model governance, privacy, security, and risk considerations in regulated environments.
