• Strong ability to work with structured, semi-structured, and selected unstructured datasets. 

• Strong familiarity with applied AI methods, including LLM-enabled workflows, text-oriented analysis, AI-assisted feature extraction, summarization, and classification. 

• Strong familiarity with notebook-based development and collaborative data science workflows, including Databricks and MLflow-supported experimentation.

• Strong written and verbal communication skills in English, including confidence in client-facing and leadership-facing settings.

• Expected to be an active adopter of approved AI-enabled analytical, coding, experimentation, documentation, and productivity workflows that improve the quality and speed of data science work. Uses AI-assisted workflows to support exploratory analysis, feature thinking, code and notebook development, model documentation, experiment design, analytical summarization, and stakeholder communication while maintaining human accountability for method selection, statistical reasoning, validation, interpretation, and final recommendations.
• Understands that AI-generated code, modeling suggestions, analytical summaries, or methodological recommendations must be reviewed against source data, assumptions, statistical rigor, business context, governance expectations, and reproducibility standards before use. Demonstrates curiosity and practical enthusiasm for applying AI to improve analytical leverage, decision support, and delivery quality without weakening scientific discipline or human judgment.
• At this level, AI fluency means using AI responsibly while helping a team adopt AI-enabled practices with consistency and care.
