• Bachelor's or associate's degree in computer science or a related field, or equivalent professional experience.

Responsibilities

• Build and maintain full-stack websites, web applications, interactive dashboards, calculators, and internal tools.
• Create interactive experiences that let users explore data by geography, time, scenario, or demographics.
• Integrate GIS data and web mapping platforms into web products.
• Develop APIs, service integrations, and data-processing workflows using Python and frameworks like FastAPI, Flask, or Django.
• Connect web products to external databases, CRMs, CDPs, and marketing platforms such as Salesforce, HubSpot, or Ortto.
• Configure and extend platforms like ArcGIS StoryMaps/Experience Builder or Tableau as project needs require.
• Set up website analytics and measurement (Google Analytics, Google Tag Manager) and apply technical SEO and performance best practices.
