Freelance Python Gis Developer Jobs in Dallas, TX

Kimley-Horn is looking for a Software Developer - 3D Visualization in our Dallas, Texas (TX) office! The position could also be located in Richardson, Texas. This is an office-based opportunity.

Kimley-Horn's Technology and Innovation team builds internal software that helps civil engineers deliver projects faster, more consistently, and with higher quality. Our work spans full-stack web applications, system integrations, AI-powered features, and interactive visualizations, ranging from focused utilities that streamline daily workflows to platforms that render CAD models, engineering data, and geospatial scenes in the browser.

In this role, you will build full-stack applications with a strong emphasis on interactive 3D and visualization. Some are conventional web applications with discrete geometric or mapping features; others are visualization-forward platforms with WebGL pipelines, CAD model viewers, or 3D geospatial scenes at their core. You will work directly with practicing engineers to understand real problems, ship solutions end-to-end, and refine them based on adoption. Additionally you will:

• Build full-stack web applications that solve real workflow problems for civil engineers, ranging from focused utilities to firm-wide platforms.
• Develop interactive visualizations that render CAD geometry, BIM models, geospatial scenes, and engineering data in the browser for review, analysis, and decision-making.
• Develop reliable backend services and modern, responsive front ends, integrating with CAD, engineering platforms, document stores, and structured and unstructured data.
• Partner with engineers and domain experts to identify high-impact opportunities, prototype solutions, refine with feedback, and productionize for firm-wide adoption.
• Maintain engineering-grade quality through testing, version control, CI/CD, and supportable releases as platforms and underlying tools evolve.

• 3+ years of professional post-grad software development experience building applications used by others. 
• Full-stack development experience with strong C#/.NET/TypeScript on the backend and a modern front-end framework (React, Blazor, Angular, or equivalent).
• Strong SQL and/or NoSQL skills with sound data modeling instincts.
• Experience with Azure Cosmos DB, including data modeling and querying for application backends.
• Hands-on experience building interactive 3D or visualization-heavy applications using Three.js, Babylon.js, WebGL, or equivalent web rendering technologies.
• Experience working with spatial, geometric, or geospatial data such as CAD geometry, BIM models, point clouds, or GIS/mapping data.
• Demonstrated use of AI-assisted coding tools (Claude Code, OpenAI Codex, or equivalent) to accelerate delivery while maintaining code quality.
• Strong communication skills and the ability to partner directly with practicing engineers, translating ambiguous needs into shipped software.

Preferred

• Experience with AEC platform SDKs such as Autodesk Platform Services (Forge), Bentley iModel.js, or IFC.js.
• Experience with applied AI development, including multi-agent workflows, RAG systems, or platforms like Azure AI Foundry and Azure AI Search.
• Python proficiency, particularly for ML, data, or AI workflows.
• Machine learning background, including model evaluation, fine-tuning, or applied ML beyond prompt-based systems.
• Experience with data lakes, lakehouses, or modern data platforms (Azure Data Lake, Microsoft Fabric, Databricks, or similar).
• Background in civil engineering or familiarity with AEC workflows (CAD/BIM, GIS, plan production, site/roadway/drainage design).

Why This Role

• Enterprise impact: Your software will be used daily by engineers delivering real infrastructure projects across the country.
• Range of work: Your day-to-day moves between standard full-stack development, system integration, and interactive visualization, building both the everyday tools engineers rely on and the more ambitious platforms that render CAD, BIM, and geospatial data in the browser.
• Strategic transformation opportunity: You will help define how a 10,000-person engineering firm builds, adopts, and scales internal software, including how interactive visualization gets woven into engineering practice.
• High ownership: You will shape architecture, influence priorities, and see your work in active use end-to-end.
