Senior Data Scientist - CBP

Description

Key Responsibilities:

• Conceptualize research problems, design studies, and lead the development of advanced analytic and ML solutions across supervised, unsupervised, NLP, graph, and (where appropriate) generative-AI techniques.
• Translate ambiguous mission questions into clearly defined hypotheses, data requirements, and modeling approaches.
• Author and review implementation roadmaps, data exploration reports, model prototype evaluations, and final model analysis reports.
• Build, validate, and harden production models — including model cards, bias and fairness assessments, drift monitoring, and reproducibility artifacts.
• Lead code reviews, establish coding standards, and mentor data scientists and analysts on the team.
  Continuously update and enhance analytic dashboards used to model real-world scenarios and identify potential mission impacts.
• Represent the team in technical reviews, working groups, and stakeholder briefings; advise senior project personnel on technical matters.
• Stay current on emerging ML, MLOps, and responsible-AI practices and recommend adoption where they advance the mission.

Requirements

• Ten (10)+ years of relevant experience in applied research, big data analytics, statistics, applied mathematics, data science, computer science, or operations research.
• Seven (7)+ years of direct experience in machine learning.
• Master's or Ph.D. in Statistics, Applied Mathematics, Data Science, Computer Science, Operations Research, or a closely related quantitative or technical discipline. (Ph.D. may substitute for up to three years of experience.)
• Demonstrated ability to create and validate data mining methods, ML models, and analytical results delivered through reporting and visualization.
• Strong communication skills covering analysis techniques, testing, and model validation processes for both technical and non-technical audiences.

Preferred Qualifications:

• Experience in financial crime, fraud detection, regulatory analytics, supply-chain, or other high-stakes mission domains.
• Hands-on experience with modern NLP / LLMs — including retrieval-augmented generation (RAG), embedding models, fine-tuning, prompt engineering, and evaluation frameworks
• Experience with graph analytics for entity resolution, network risk, and link analysis.
• Experience with MLOps pipelines, feature stores, model registries, and production monitoring for drift and bias
  Publications, patents, or open-source contributions in machine learning.
