Job Description 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. The system includes multiple Python scripts for data processing, automation, a SQL Server database, Esri file geodatabases, a PHP‑based web interface for configuring and running geocoding jobs, and a manual geocoding interface built with the ArcGIS JavaScript API. Geocoding workflows leverage locally installed software, ArcGIS Server‑based services, and the Google Maps API.
In this contract position, you will improve maintainability, clarity, and structure of the existing Python codebase. Core responsibilities include refactoring scripts that handle geocoding logic, address standardization, data validation, and geospatial enrichment. The refactored code should follow Python best practices (PEP 8), improve error handling and logging, and allow for more efficient testing, debugging, and future enhancement.
Key Responsibilities
Assess the current Python codebase, workflows, and dependencies related to geocoding and spatial data processing.
Refactor and modernize existing Python scripts to improve code readability, modularity, and adherence to best practices (e.g., PEP 8, logging, error handling).
Maintain and improve integration with multiple geocoding services, including locally installed software, ArcGIS Server REST‑based services, and Google Maps Geocoding API (including quota management and API key security).
Transition data processing from flat files (CSVs, Esri file geodatabases) to an ArcGIS Enterprise Geodatabase (SQL Server).
Implement robust logging, error handling, and validation throughout the codebase.
Optimize and document fallback logic for handling geocoding failures and manual resolution workflows.
Produce high‑quality technical documentation, including code comments, usage instructions, architecture diagrams, and workflow documentation.
Improve the logging and reporting framework for better error tracking and system transparency.
Collaborate with internal GIS and IT staff for requirements clarification, testing, and implementation support.
Required Skills & Experience
Core Technical Proficiency
Advanced Python proficiency with clean, modular code for data processing and automation. Familiarity with PEP 8, logging, and error handling; libraries may include pandas, os, shutil, logging, arcpy, pyodbc, requests.
Experience using ArcPy for spatial joins, geoprocessing, and field calculations.
Strong understanding of SQL Server databases, including querying and updating tabular data; working knowledge of geospatial data stored in ArcGIS Enterprise Geodatabases.
Experience with third‑party geocoding APIs, especially Google’s Geocoding API (authentication, usage limits, and response parsing).
Familiarity with API security protocols such as OAuth2, API keys, or JWT.
Software Development Best Practices – adherence to PEP 8 and modular design principles; use of Git for version control and collaboration; 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.
Deliverables
Refactored Python scripts with improved structure, documentation, and testability.
Modularized codebase that supports future enhancements and integration of new geocoding services.
Revised error handling and logging mechanisms.
Documentation including code comments, docstrings, developer setup instructions, system architecture diagram or data flow chart.
Updated configuration files and batch scripts (if applicable).
Knowledge transfer sessions to internal staff.
Qualifications
Education
– Bachelor’s degree in Computer Science, Geographic Information Systems, Software Engineering, or a related field. Equivalent professional experience may be substituted for formal education.
Experience
– Minimum of 5 years of experience in Python development; demonstrated experience refactoring or modernizing existing codebases for improved maintainability and performance.
Experience working with government or public health organizations is a plus.
