Full Stack Web Developer (React/ArcGIS)

We are seeking a highly skilled GIS Web Developer to lead the design and implementation of high-performance geospatial applications. You will bridge the gap between complex spatial analysis and modern user interfaces, leveraging the ArcGIS Maps SDK for JavaScript and the React framework to deliver location intelligence solutions.

Core Responsibilities

• Application Development: Design and develop responsive, scalable web applications using React Hooks, TypeScript, and State Management libraries (e.g., Redux, Context API).
• ArcGIS Integration: Implement complex mapping features using ArcGIS Maps SDK for JavaScript (4.x), including 2D/3D visualizations, feature layers, and spatial queries.
• Custom Widget Development: Build and extend custom widgets for ArcGIS Experience Builder (Developer Edition) to meet unique business requirements.
• Spatial Data Engineering: Optimize interaction with ArcGIS REST APIs and Feature Services to minimize latency and improve geometry rendering performance.
• UI/UX Standards: Utilize the Esri Calcite Design System to ensure consistent, accessible, and user-centric design across all geospatial tools.
• Collaboration: Partner with GIS Analysts and Stakeholders to translate business needs into technical specifications and lead code reviews for junior developers.

Required Technical Skills

• Frameworks: 5+ years of experience with React (Functional Components, Hooks) and modern front-end build tools like Vite or Webpack.
• GIS Platforms: Proven expertise in the Esri Ecosystem, including ArcGIS Online, ArcGIS Enterprise, and ArcGIS Pro.
• Mapping APIs: Deep knowledge of ArcGIS Maps SDK for JavaScript, including spatial analysis, geoprocessing services, and OAuth 2.0 authentication.
• Geospatial Fundamentals: Strong understanding of coordinate systems (WGS84, Web Mercator), projections, and spatial algorithms.
• Data & Back-end: Proficiency in SQL (PostGIS or SQL Server) and scripting with Python (ArcPy) for data automation.

Qualifications

• Education: Bachelor’s or Master's degree in Computer Science, GIS, or a related STEM field.
• Experience: Minimum 5 years of professional software development experience, with at least 3 years focused on ArcGIS web applications.
• Soft Skills: Exceptional problem-solving abilities and the ability to explain complex spatial concepts to non-technical audiences.
