Senior Data Scientist (NLP and Unstructured Data Analytics)

Location: Herndon, VA (Remote Work)

Must have a Public Trust Clearance

KEY RESPONSIBILITIES

• Integrate and scale natural language processing methods to parse, clean, and analyze large corpora of unstructured and semi structured text, using optical character recognition, semantic similarity algorithms, and large language models as needed.
• Design, develop, test, calibrate, and implement statistical and machine learning models targeting financial fraud, improper payments, and non compliance within SBA programs.
• Build and refine supervised and unsupervised models, including regression, Bayesian, clustering, and ensemble approaches.
• Review, maintain, and support all existing loan fraud indicators developed by TSD.
• Perform data quality analysis on source tables and develop repeatable processes for combining and analyzing large data sources.
• Collaborate directly with criminal investigators to determine and execute analytic strategies supporting loan fraud cases, and adhere closely to the federal rules of criminal procedure governing protected information, including Rule 6(e).
• Develop case leads for SBA OIG investigations from model outcomes.
• Document all methodology, test models, and production models in a form that satisfies criminal evidentiary requirements.
• Build visualizations and dashboards conveying methodological choices, outcomes, and predictive capability, iterated on end user feedback.
• Deliver findings in multiple registers: data summaries and visualizations for investigative staff, executive summaries for OIG leadership.
• Coordinate with the data engineering seat so the architecture supports machine learning and text processing pipelines efficiently.
• Create programming and automation techniques using SharePoint, Python, Excel, Power BI, Power Apps, and similar tools.
• Identify new business questions that expand the scope of analysis and reporting.

Required

Education

Master's, Ph.D., or doctorate level equivalent degree in data science, machine learning, computer science, mathematics, or a related field. Alternatively, ten years of applied work experience in any of the same fields.

• 5+ years Designing, implementing, and maintaining advanced AI systems and predictive models, including both supervised and unsupervised models.
• 5+ years Developing analytic rules and models using leading edge analytic tools and best practices.
• 5+ years Developing regression, classification, and other statistical models to identify anomalies, patterns, and predictive variables.
• 3+ years Providing data support for criminal investigations into financial fraud or abuse of government funds.
• 3+ years Manipulating data in Python. Pandas is required.
• 3+ years Working in a modern cloud environment: Azure, AWS, or GCP. Certifications preferred.
• 2+ years Conducting advanced data analysis in SQL, specifically SQL Server and PostgreSQL.
