Location: Dehradun (on-site / hybrid) • Type: Full-time • Experience: 3+ years • Reports to: Technical Team Lead

About the role

You will make sure the right ambulance goes to the right place. You own geocoding, spatial queries and road-network routing, which turn a caller's location into a ranked list of units by real driving time.

Responsibilities

- Design spatial schemas and GiST indexes in PostgreSQL/PostGIS for incidents, stations, facilities and geofences.
- Build the spatial service: nearest-unit search, then ranking by road ETA.
- Self-host and tune OSRM or Valhalla on an India OpenStreetMap extract, including scheduled map updates.
- Set up and tune geocoding (Nominatim or Pelias) for Indian addresses and landmarks.
- Design geofencing, coverage zones and spatial alerts.
- Serve map data to the dispatcher console and responder app as GeoJSON and vector tiles.




- Measure and improve location accuracy and ETA error against real trips.

Requirements

- 3+ years of GIS software engineering.
- Robust PostgreSQL/PostGIS: spatial SQL, indexing, projections and coordinate transforms.
- Hands-on with at least one routing engine (OSRM, Valhalla or GraphHopper).
- Fluent with GeoJSON and web-mapping formats.
- Able to write production services in C# / .NET, or willing to learn it from Python or Java; we budget ramp-up time for this.

Nice to have

- OpenStreetMap data processing (osmium, osm2pgsql).
- Vector tile pipelines (Tippecanoe, Martin, tileserver).
- Experience with Indian address data quality.
- Fleet, logistics or ride-hailing dispatch background.
