Vantor is seeking a Geospatial Developer to design, build, and support high-impact geospatial applications, REST integrations, and data pipelines across our enterprise GIS environment. In this role, you will bridge the gap between technical GIS development and business needs, translating functional requirements into scalable web applications, automated geoprocessing services, and advanced data collection tools.
The ideal candidate brings deep technical expertise in Esri enterprise architecture—including ArcGIS Enterprise/Portal, ArcGIS Pro, Experience Builder Developer Edition, and Survey123—alongside demonstrated experience exposing geospatial REST services to external enterprise systems, proprietary search engines, and lightweight 3D clients (ArcGIS Earth).
Responsibilities:
Custom Web & Widget Development
Design, build, and maintain custom widgets and extensions using ArcGIS Experience Builder (Developer Edition) (React/TypeScript).
Integrate custom widgets with underlying Enterprise Portal web maps, feature services, and geoprocessing tasks.
Optimize client-side rendering and user experience (UX) for specialized analytical workflows.
Enterprise Services, Geoprocessing & REST Integration
Author, publish, and manage robust ArcGIS Enterprise / Portal Services, with an emphasis on custom geoprocessing (GP) tools and spatial analysis web services.
Expose and optimize ArcGIS Server/Portal REST endpoints (Feature Services, Map Services, Query Services, and GeoJSON endpoints) for seamless consumption and indexing by proprietary enterprise search engines and external indexing engines.
Automate data preparation and back-end tasks using Python (ArcPy, ArcGIS API for Python) to support enterprise analytic services.
Dashboard Backends
Engineer and maintain optimized data layers, views, and back-end geodatabase architectures in ArcGIS Pro and Portal to power high-performance operational dashboards (ArcGIS Dashboards).
Establish automated ETL routines to ensure real-time or near-real-time synchronization between spatial databases and dashboard reporting layers.
Advanced Field & Data Collection Systems
Architect and implement complex ArcGIS Survey123 forms utilizing advanced XLSForm logic (cascading selects, nested repeats, dynamic calculations, custom validation expressions, and pull data functions).
Integrate Survey123 workflows with webhooks, automated notifications, and post-submission geoprocessing tasks.
Cross-Portal Migration & Content Governance
Plan and execute secure, reliable content and data migrations across disparate ArcGIS Enterprise Portals (e.g., Development Staging Production, or cloud-to-cloud/tenant-to-tenant).
Utilize the ArcGIS API for Python to script repeatable migration pipelines for web maps, hosted feature layers, user permissions, and associated assets.
