Requirements

3+ years of professional experience and demonstrated ability in most of the following areas:
JavaScript technologies such as React and TypeScript
Node.js backend frameworks, particularly NestJS
Python web backend frameworks, particularly FastAPI
Relational databases and SQL, with comfort reading and writing analytical queries against cloud data warehouses (e.g. Google BigQuery)
Core knowledge of fundamental web protocols and standards (HTML5, HTTP, WebSockets, CORS, cookies and session management, etc.)
Cloud computing and infrastructure, especially Google Cloud Platform
Client-side mapping using Mapbox GL JS, including working with vector tiles, GeoJSON, and custom source/layer/style configuration
Spatial data in relational databases, particularly PostGIS, including spatial indexes and SQL-level geometric operations
Demonstrated ability to optimize web applications for performant client-side rendering of large datasets — familiarity with strategies such as vector tiles, virtualization, web workers, data decimation, client-side caching (IndexedDB), React performance profiling, and GPU-accelerated rendering
Automated testing frameworks, particularly end-to-end browser testing (e.g. Playwright)
Practical experience using AI/LLM coding assistants and a demonstrated ability to integrate them productively into development workflows
