Build, query, and maintain knowledge graphs (Neo4j, JanusGraph, Vantage, ADVANA) to capture relationships among entities. Mine and analyze structured/unstructured datasets to identify trends, correlations, and mission-relevant insights. Develop predictive models, simulations, and algorithms to support operational decision-making. Perform ETL processes to integrate and validate data from multiple Army and enterprise sources. Visualize and present findings to stakeholders using dashboards, reports, and knowledge graph queries. Coordinate with cross-functional and joint teams to implement models and monitor outcomes. Knowledge/Skills/Abilities
Strong problem-solving skills with an emphasis on mission-focused data science. Proficiency in statistical computer languages (Python, R, SQL) for data manipulation and analysis. Experience working with and creating data architectures, including semantic/ontology-driven frameworks. Knowledge of machine learning techniques (clustering, regression, neural networks, decision trees) and their real-world applications. Familiarity with semantic technologies and tools: RDF, OWL, SHACL, Protégé. Experience with graph databases and query languages: Neo4j, JanusGraph, SPARQL, Cypher. Hands-on experience with ETL processes and distributed data/computing tools (Hadoop, Spark, Hive, NiFi). Strong skills in data visualization (Tableau, Power BI, Matplotlib, Seaborn, ggplot). Excellent written and verbal communication for coordination across Army, joint, and interagency teams. Qualifications
5–7 years of experience manipulating datasets, building statistical models, and applying advanced analytics. Master’s or PhD in Statistics, Mathematics, Computer Science, Data Science, or a related quantitative field. Experience designing and implementing semantic models and knowledge graphs.
