Job summary

PathGen-AI is building a containerized geospatial analytics platform blending an interactive web UI, a Python analytics API backed by DuckDB, and raster tile services for COG datasets. You will collaborate with data engineers and frontend developers to ship end-to-end data pipelines, geospatial correctness, and scalable user workflows.

As a senior engineer, you will optimize SQL, drive real-time data delivery, and craft map-centric dashboards.

Qualifications

• Strong TypeScript + React experience building map-driven SPAs.
• Strong SQL and analytical mindset; familiarity with columnar/Arrow data exchange.
• Experience building reactive data architectures with centralized state coordination.
• Expertise in geospatial query optimization across vector (DuckDB/PostGIS) and raster (COG/TiTiler) data sources.
• Practical experience with COGs and raster tooling (rasterio, rio-tiler, TiTiler-like systems).
• Comfort with containerized, multi-service development and E2E testing (Playwright or equivalent).

Responsibilities

• Deliver features end-to-end across UI, APIs, and geospatial services.
• Design and optimize analytical schemas and SQL (DuckDB) for performance.
• Implement real-time query and data delivery via WebSockets/streaming plus REST endpoints.
• Build interactive, map-centric dashboards with correct geospatial interpretation and responsive UI.
• Build coordinated, interactive analytics so actions in one view update all others.
• Improve performance and reliability through profiling, caching, defensive data handling, and sane defaults.
• Strengthen developer experience via reproducible Docker workflows and robust automated testing.
