Expertise with data visualization tools (e.g., Tableau, Matplotlib).
Experience processing large datasets, deploying LLMs in government cloud data platforms (e.g., Azure ADLS/Databricks/Azure ML, or equivalents).
Comparative understanding of LLMs (e.g., Claude Code, ChatGPT) and tradeoffs in terms of capabilities, cost, and performance.
Excellent problem-solving skills and the ability to think critically and analytically to address complex research challenges.
Exceptional verbal and written communication skills and a bias toward rigor, clarity, and defensibility over black-box modeling.
Familiarity with FISMA/NIST/Zero Trust security frameworks.
Current Principal Data Scientist (PDS) Certification.
U.S. Citizenship required.
Preferred Qualifications:
Experience with Spark/Databricks.
PhD preferred in Statistics, Mathematics, or a related quantitative field.
