Senior Data Scientist

Index Analytics, LLC, is a rapidly growing, Baltimore-based small business providing health-related consulting services to the federal government. At the center of our company culture is a commitment to instilling a dynamic and employee-friendly place to work. We place a priority on promoting a supportive and collegial team environment and enhancing staff experience through career development and educational opportunities.

Index Analytics is seeking a Senior Data Scientist to support Government clients in the Baltimore and Washington D.C. Metro Area. This resource will create value from structured and unstructured data by applying domain knowledge, statistical analysis, and advanced machine learning techniques to solve complex healthcare challenges.

This role emphasizes end-to-end development of machine learning and AI systems, including traditional ML, deep learning, NLP, and modern LLM-based architectures such as Retrieval-Augmented Generation (RAG) and agentic AI systems. The Senior Data Scientist serves as a technical leader on AI initiatives, helping guide solution design, mentor data scientists, and establish technical best practices while remaining a hands-on contributor. This role is expected to have a demonstrated track record of successfully deploying AI and machine learning solutions into production environments, preferably within federal government or other regulated settings.

This position requires an in-person interview at our HQ.

Responsibilities

• Serve as a technical lead on AI and machine learning initiatives, providing guidance on solution architecture, model selection, implementation approaches, and technical best practices.
• Mentor and support junior and mid-level data scientists through code reviews, knowledge sharing, technical coaching, and collaborative problem solving.
• Establish and promote best practices for MLOps, model evaluation, model monitoring, reproducibility, and responsible AI development
• Build and deploy end-to-end ML pipelines on AWS (e.g., SageMaker, S3, Glue) for scalable training, evaluation, and inference.
• Develop and implement advanced NLP solutions, including text classification, entity recognition, topic modeling, and semantic search using models such as BERT and transformer-based architectures.
• Design, build, and productionize RAG (Retrieval-Augmented Generation) systems, including document ingestion, embedding pipelines, vector search, and LLM orchestration.
• Develop LLM-powered applications, including prompt engineering, evaluation frameworks, and optimization techniques for accuracy, consistency, and cost.
• Contribute to agentic AI system design, including multi-step reasoning workflows, tool use, and orchestration of LLM-driven agents for complex tasks.
• Implement predictive analytics and statistical modeling to uncover patterns, trends, and insights from healthcare data.
• Evaluate emerging AI technologies, frameworks, and techniques and recommend their appropriate application to government healthcare use cases.
• Perform data mining and exploratory data analysis (EDA) using state-of-the-art techniques across structured and unstructured datasets.
• Contribute to technical leadership across multiple AI initiatives while remaining an active hands-on developer and model builder.
• Build data visualizations, dashboards, and analytical tools to communicate findings clearly to technical and non-technical stakeholders.
• Evaluate model performance using appropriate metrics (e.g., accuracy, AUC, precision/recall) and present results in a clear, actionable manner.
• Collaborate in an Agile environment with cross-functional teams including engineers, analysts, and stakeholders.
• Recommend data-driven solutions and AI strategies aligned with CMS business needs and healthcare policy objectives.
