Job descriptions & requirements

Responsibilities:

Route & Geospatial Architecture:

• Design the platform's geospatial architecture using PostgreSQL/PostGIS.
• Convert transportation routes into accurate digital route geometries and service corridors.
• Develop geofencing and route-validation functionality.
• Determine whether passenger pickup and destination locations can be served by particular routes.
• Identify overlapping routes and route intersections.
• Develop efficient spatial indexing and querying strategies.

GPS & Vehicle Tracking:

• Process real-time GPS data from moving vehicles.
• Develop methods for handling inaccurate, noisy or drifting GPS coordinates.
• Implement map matching to determine the road/route on which a vehicle is actually travelling.
• Determine vehicle direction and route progression.
• Develop vehicle-on-route/off-route detection.
• Support real-time vehicle-location services.

Routing & Pickup Optimization:

• Integrate and/or develop road-network routing capabilities.
• Calculate road-based distance and travel time rather than relying solely on straight-line distance.
• Determine suitable passenger pickup/drop-off points.
• Calculate permissible route deviations.
• Support intelligent passenger-to-vehicle matching.
• Work with routing technologies such as OSRM, Valhalla, GraphHopper or equivalent.

APIs & Backend Integration:

• Develop or support geospatial REST APIs.
• Integrate geospatial services with the existing application backend.
• Optimize PostGIS queries for real-time operation.
• Work with developers responsible for the driver and passenger applications.
• Design geospatial services capable of scaling as vehicle and passenger volumes increase.

Requirements:

• Bachelor's degree or higher in one of the following, or equivalent professional experience:
• A minimum of 3–5 years of professional geospatial software engineering experience.
• Computer Science, Software Engineering, Geoinformatics
• Geomatics, Geographic Information Systems
• Surveying/Geospatial Engineering, Transportation Engineering
• Geography with significant software-development experience
