Leidos is seeking a Senior Data Scientist with strong machine learning development and coding expertise to support a customer mission in Springfield, VA. Russian language proficiency is a strong plus, but not required.

An active TS/SCI clearance with willingness to obtain a Polygraph is required to be considered.

This position is focused on advanced data science and machine learning development within a GEOINT mission space. The ideal candidate brings strong coding, model development, and analytic problem-solving skills, with the ability to integrate geospatial and multi-source data to deliver mission impact. Russian language and geospatial linguistic experience are considered a plus, but not required. The selected candidate will exploit, analyze, and produce imagery-derived intelligence products while integrating foreign geographic names data, native-language sources, and geospatial metadata to enhance analytic accuracy and mission impact.

The analyst will work closely with Intelligence Community (IC) partners, geographic names experts, and multi-INT analysts to ensure imagery-derived assessments are geospatially precise, linguistically accurate, and operationally relevant.

Accuracy, analytic rigor, and mission responsiveness are essential.

Primary Responsibilities

• Design, develop, train, and deploy machine learning models to solve complex mission problems.

• Write production-quality code in Python (or similar) to support model development, testing, and deployment.

• Structure disparate and unstructured data (imagery, text, geospatial features) into usable formats for quantitative analysis and fusion.

• Develop and maintain scalable data pipelines to support automated analytic workflows.

• Build and apply statistical models, machine learning algorithms, and data processing techniques for pattern detection and predictive analysis.

• Generate automated workflows to improve efficiency, reproducibility, and scalability of analytic production.

• Aggregate existing data stores and enable natural language processing (NLP) query capabilities using existing APIs.

• Process and analyze large volumes of unstructured data and documents to extract mission-relevant insights.

• Integrate geospatial and multi-source data into advanced analytic workflows.

• Translate complex quantitative findings into clear, actionable insights through visualization and storytelling.

• Collaborate with cross-functional teams to deliver scalable, mission-focused data science solutions.

• Brief findings clearly and confidently to technical and non-technical audiences.

Basic Qualifications

• Active TS/SCI clearance with willingness to obtain a Polygraph.

• Bachelor’s degree and 12+ years of relevant experience, or Master’s degree and 10+ years of relevant experience in Data Science, Computer Science, Analytics, or related field. Additional experience may be considered in lieu of degree.

• Demonstrated senior-level experience designing, training, and deploying machine learning models.

• Strong coding skills in Python (or similar), with experience building scalable and maintainable solutions.

• Demonstrated experience applying data science methodologies (machine learning, statistical analysis, data engineering) to real-world problems.

• Experience structuring and processing large, complex, and unstructured datasets.

• Experience processing unstructured data and documents (e.g., text, reports, open-source content).

• Experience developing or supporting NLP capabilities, including querying across aggregated data sources.

• Strong understanding of data pipelines, feature engineering, and model evaluation techniques.

• Experience working with geospatial data and integrating spatial context into analytic workflows.

• Strong research, critical thinking, and analytic writing skills.

• Familiarity with working in high-side (classified) environments.

• Experience operating effectively in fast-paced, mission-driven environments both independently and as part of a team.

• Familiarity with working in high-side (classified) environments.

Desired Qualifications

• Russian language proficiency (ILR 2+ or higher).

• Experience working with geospatial linguistics, toponymy, or foreign geographic data.

• Regional expertise in Russian Federation and/or Russian-influenced geographies.

• Experience developing machine learning models or AI-enabled analytics within national security or GEOINT environments.

• Proficiency in Python for advanced analytics, automation, or data engineering workflows.

• Experience developing ontologies, schemas, or knowledge graphs.

• Experience integrating multi-INT or multi-source data into advanced analytic workflows.

• Prior experience briefing senior government stakeholders.
