Python Developer

Must be able to work on W2

Overview: The Arizona Department of Health Services (ADHS) is seeking a skilled and experienced Python developer to modernize and refactor the Python codebase that supports an existing full-stack geocoding system. This system includes multiple Python scripts for data processing and automation, a SQL Server database, Esri file geodatabases, and a PHP-based web interface for configuring and running geocoding jobs. It also features a manual geocoding interface built with the ArcGIS JavaScript API. Geocoding workflows leverage a combination of locally installed geocoding software, ArcGIS Server-based geocoding services, and the Google Maps API.

Experience working with third-party geocoding APIs, especially Google’s Geocoding API (including authentication, usage limits, and response parsing)

Familiarity with API security protocols such as OAuth2, API keys, or JWT

Understanding of API authentication and security protocols

Software Development Best Practices

Adherence to PEP 8 and modular design principles

Use of Git for version control and collaboration

Experience writing clean, maintainable, and well-documented code

Comfortable working independently and delivering clear, reliable deliverables in a contract environment

Preferred Qualifications

Experience modernizing or rewriting legacy Python codebases

Familiarity with geocoding accuracy scoring, fallback strategies, and manual resolution workflows

Prior work with public health, government, or GIS teams is a plus
