  • Build and administer web GIS services (ArcGIS Server, ArcGIS Online/Enterprise, GeoServer) including map services, feature services, WMS/WFS, and REST APIs for internal and public consumption.
  • Author and maintain spatial ETL procedures and data pipelines to integrate CAD, BIM, sensor feeds, CSVs, shapefiles, raster layers, and third-party APIs into centralized geodatabases with robust transformation rules and provenance tracking.
  • Implement and enforce geospatial data governance policies, including coordinate reference system standards, topology rules, naming conventions, metadata compliance (FGDC/ISO), and data lifecycle management.
  • Perform raster and remote sensing image processing (orthorectification, mosaicking, classification, NDVI, change detection) for satellite and aerial imagery to extract land cover, vegetation indices, impervious surfaces, and other thematic products.
  • Conduct LiDAR point cloud processing and classification (ground, vegetation, building), create digital elevation/terrain models (DEM/DTM), and derive hydrologic and slope analyses for infrastructure and flood modeling projects.
  • Optimize spatial queries and database performance by creating indexes, tuning SQL/PostGIS statements, and monitoring service performance to ensure fast map rendering and query response times.
  • Support network analysis and modeling (routing, service area, closest facility, transportation analytics) to inform logistics, emergency response planning, and utilities operations.
  • Integrate GIS with enterprise systems (asset management, ERP, SCADA) through APIs and webhooks to maintain synchronized spatial and attribute data across platforms.
  • Produce repeatable reports, dashboards, and storymaps (ArcGIS Dashboards, Power BI integration) that communicate geospatial insights to stakeholders and leadership in an intuitive, data-driven format.
  • Lead or participate in stakeholder workshops to gather functional requirements, translate business questions into spatial queries, and prioritize geospatial deliverables aligned to project goals.
  • Validate, clean, and reconcile spatial attribute data and tabular datasets; perform data matching, deduplication, and geocoding to ensure high-quality location intelligence and accuracy.
  • Prepare technical documentation, standard operating procedures, metadata records, and training materials necessary for team adoption and handover of geospatial workflows and solutions.
  • Provide technical support and training to internal users on GIS tools, web mapping applications, and data access protocols to increase geospatial literacy across the organization.
  • Manage project tasks and timelines, coordinate with vendors and contractors for specialized geospatial services (orthophoto production, LiDAR acquisition), and ensure deliverables meet specifications and budgets.
  • Evaluate new geospatial technologies, open-source tools, and cloud services (AWS, Azure geospatial offerings) and make recommendations for adoption to modernize GIS infrastructure.
  • Conduct spatial risk assessments, suitability, and environmental impact analyses to support regulatory compliance, permitting, and strategic planning efforts.
  • Execute geocoding, address standardization, and spatial joins for demographic, cadastral, and parcel-level analyses supporting utilities, real estate, and public works decision-making.
  • Implement version control and change management strategies for geospatial datasets and map services to track edits, enable rollback, and support multi-user editing workflows.
  • Develop reproducible spatial analysis scripts and unit-tested geoprocessing modules to enable sharing and reuse across teams and to support DevOps/CI-CD practices in GIS development.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
  • Assist in procurement and vendor evaluation for GIS software licenses, data subscriptions, and imagery services.
