security clearance: Public Trust (ability is required)

seeking a Senior Data Scientist who will work closely with client stakeholders to support economic analysis of national importance through application of advanced statistics and data science techniques and technologies. In this position, you will utilize your strong background in statistics, machine learning, generative AI, visualization, economic analysis, and big data processing to plan and execute projects to meet business client data needs.

Requirements
Partner with stakeholders to scope questions and assumptions, support solution design, and facilitate project execution
Design and implement robust data ingestion, storage, integration, processing, retrieval, and management strategies for research datasets
Build transparent, reproducible pipelines and analysis environments in cloud infrastructures
Produce crisp exhibits and memos that explain methods, limitations, and uncertainty
Facilitate and execute data-driven research by applying sophisticated statistical, machine learning, and computational methods to analyze complex datasets related to computer and information science
Create compelling data visualizations and reports that convey complex research findings in a clear and accessible manner to both technical and non-technical stakeholders
Support defensible analytics and econometric/causal inference workstreams, translating ambiguous business or legal questions into testable hypotheses and clear, client-ready findings
Design and execute rigorous studies (e.g., difference-in-differences, panel models with fixed/random effects, instrumental variables/2SLS, time series/forecasting, etc.) to turn multi-source datasets into documented, auditable results
Mentor teammates on best practices
Stay updated on the latest academic research and industry advancements in data science, AI, and information systems, and apply relevant findings to ongoing projects

Expertise with application of AI to deliver insights with optimal performance, cost savings, etc. using structured, unstructured data
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 are essential
Familiarity with FISMA/NIST/Zero Trust security frameworks
Current Principal Data Scientist (PDS) Certification

Preferred
Experience with Spark/Databricks.
Domain exposure to antitrust, pricing, healthcare claims, fraud/forensics, or financial analysis is a plus.
Experience producing reproducible, peer-reviewed-method analyses that meet Rule 702/Daubert reliability requirements and can withstand Daubert challenges (methods, error rates, standards/controls, and appropriate bounds on conclusions)
Contribution to open-source projects or participation in relevant data science communities.
