• Spot Verification: Evaluate and benchmark third-party geocoding services (e.g., Google, Mapbox, Overture Maps, etc.) vs. in-house builds to validate consistency and/or differentiation.
• Quality Frameworks: Evolve automated “confidence” scoring systems to measure and report on the "health" of our addressing and geocoding data over time.
• Ideate, iterate and implement enhancements to the geocoding stack to unlock higher accuracy, explainability and currency
• Perform hands-on experimentations using modern open-source, cloud native geospatial tools, and collaborate with engineering team to take features from idea to production
