Senior Frontend Developer

We are looking for a Senior Developer with Angular experience to lead the frontend development of a complex, GIS-driven web application built from the ground up. The system will deliver advanced geospatial visualization and interaction capabilities using technologies such as OpenLayers and potentially CesiumJS for 3D mapping.

This is a hands-on role requiring strong architectural thinking, deep Angular expertise, and the ability to handle performance-intensive geospatial data in a rich client application.

Key Responsibilities:

Architect and develop a scalable Angular application from scratch, establishing best practices and coding standards
Design and implement advanced interactive map features using OpenLayers and/or CesiumJS
Integrate with backend REST APIs delivering geospatial data (e.g., GeoJSON, vector data)
Work with map services (e.g., MapServer, OGC-compliant WMS/WMTS) and ensure efficient data rendering
Optimize performance for large datasets and complex map interactions
Build reusable, maintainable, and testable UI components
Collaborate closely with backend developers, product managers, and domain experts
Lead technical decisions on frontend architecture and mapping technologies
Mentor other developers and contribute to code reviews and technical standards

Requirements:

Required Qualifications:

5+ years of experience in frontend development, with strong expertise in Angular (latest versions), TypeScript, and RxJS
Proven experience building complex, high-performance web applications from scratch
Strong understanding of REST API integration and asynchronous data flows
Experience with at least one web mapping library (OpenLayers, Mapbox GL JS, Leaflet, or similar)
Solid understanding of application architecture, modular design, and state management
Experience working with Git and modern development workflows

Preferred Qualifications:

Hands-on experience with OpenLayers and/or CesiumJS
Familiarity with GIS concepts such as coordinate systems, projections, spatial indexing, and geospatial data formats
Experience integrating with OGC map services
Experience rendering and optimizing large geospatial datasets in the browser
Familiarity with 3D visualization or WebGL-based frameworks
