• Use Python, Tableau, ArcGIS, and related tools to process large datasets, automate workflows, prepare data for analysis, and build visual analytics products.
• Partner with mission users to understand geospatial data needs, analytic questions, visualization requirements, and operational workflows.
• Identify, acquire, clean, transform, validate, curate, and publish large geospatial and tabular datasets from diverse sources.
• Develop Python scripts and tools to automate geospatial data processing, quality control, enrichment, transformation, and publication workflows.
• Manage and update ArcGIS Portal content, including hosted feature layers, map services, web maps, dashboards, data hubs, and related geospatial products.
• Build and maintain Tableau dashboards, reports, and analytic visualizations for the data processing office and mission stakeholders.
• Apply cartographic design and usability practices such as symbology, labeling, layer management, metadata practices, and performance tuning.
• Integrate structured, unstructured, tabular, and spatial datasets into cohesive analytical and visualization environments.
• Support geospatial data library functions, including dataset organization, metadata creation, version management, quality control, discoverability, and lifecycle maintenance.
• Develop documentation including data dictionaries, standard operating procedures, user guidance, and technical recommendations to support repeatable workflows.
