🎯 Role Definition

A Geospatial Developer is a specialized software engineer who designs, develops, and implements systems and applications centered around geographic data and spatial analysis. This role is the critical link between the worlds of software development, data engineering, and geographic information science (GIS). They are the architects behind the tools we use to understand our world spatially—from interactive web maps and satellite imagery processing pipelines to complex location-based services. This professional doesn't just analyze spatial data; they build the robust, scalable software solutions that make that analysis possible for others, turning raw location data into actionable intelligence and intuitive user experiences.

  • Automate complex GIS workflows and geoprocessing tasks using scripting languages like Python, leveraging libraries such as ArcPy, GDAL/OGR, and GeoPandas.
  • Develop and optimize spatial databases (e.g., PostgreSQL/PostGIS, SQL Server Spatial, Oracle Spatial) for efficient storage, indexing, and querying of geographic data.
  • Build interactive and user-friendly web mapping applications using modern front-end libraries and frameworks (e.g., Leaflet, Mapbox GL JS, OpenLayers, React, Esri's ArcGIS API for JavaScript).
  • Publish, manage, and secure geospatial web services (e.g., WMS, WFS, Vector Tile Services, Image Services) using platforms like ArcGIS Enterprise, GeoServer, or custom server solutions.
  • Integrate geospatial capabilities into broader enterprise systems and business applications, ensuring seamless data flow and functionality.
  • Perform advanced spatial analysis, geostatistical modeling, and raster analysis to derive insights and support complex business or research questions.
  • Implement and deploy containerized geospatial applications and services using technologies like Docker and Kubernetes for improved scalability and portability.
  • Leverage cloud platforms (AWS, Azure, GCP) to build and manage cloud-native geospatial infrastructure, utilizing services like S3/Blob Storage, EC2/VMs, Lambda/Functions, and managed databases.
  • Develop custom tools, add-ins, and extensions for desktop GIS software (e.g., ArcGIS Pro, QGIS) to enhance functionality for GIS analysts and other users.
  • Conduct performance tuning and optimization of geospatial queries, applications, and services to ensure rapid response times and efficient resource utilization.
  • Implement and maintain version control for code and geospatial data workflows using systems like Git.
  • Create and maintain comprehensive technical documentation for developed applications, APIs, and data processing workflows.
  • Research and evaluate emerging geospatial technologies, standards, and methodologies to drive innovation and continuous improvement within the team.
  • Collaborate closely with product managers, UI/UX designers, and data scientists to translate requirements into functional and technically sound geospatial solutions.
  • Write unit, integration, and end-to-end tests for geospatial code to ensure quality, reliability, and correctness of outputs.
  • Administer and maintain GIS server environments, including ArcGIS Enterprise or open-source alternatives, ensuring system health and availability.
  • Process and analyze satellite imagery and other remote sensing data, developing algorithms for feature extraction, change detection, and classification.
  • Develop solutions that adhere to OGC (Open Geospatial Consortium) standards to promote interoperability between different geospatial systems.
  • Troubleshoot and resolve complex technical issues related to spatial data, geoprocessing algorithms, and application performance.

Secondary Functions

  • Support ad-hoc data requests and exploratory spatial data analysis for various business units.
  • Contribute to the organization's broader data governance and data quality strategy, with a focus on geospatial assets.
  • Collaborate with business units to translate their location-based questions and needs into tangible engineering requirements.
  • Participate actively in sprint planning, daily stand-ups, and retrospective ceremonies within an agile development team.
  • Mentor junior developers and GIS analysts, providing guidance on best practices in geospatial development.
