Kimley-Horn is looking for a Software Developer - Applied AI in our Jacksonville, Florida (FL) office! The position could also be located in Tampa, St. Petersburg, Sarasota, or Orlando. 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, and AI-powered features, ranging from focused utilities that streamline daily workflows to deeper platforms that bring multi-agent and retrieval-augmented systems into engineering practice.

In this role, you will build full-stack applications across that spectrum. Some are conventional web applications with discrete AI integrations; others are built around retrieval-augmented generation, multi-agent orchestration, or similar applied AI architectures. 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.
• Integrate AI capabilities where they create value, including multi-agent workflows, RAG pipelines, and intelligent assistants on top of engineering data.
• 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 models 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 designing and shipping AI multi-agent workflows.
• Practical experience building production RAG systems with Azure AI Search, including chunking, embedding, retrieval, and grounding strategies.
• Experience with Azure AI Foundry for building, deploying, and operating AI applications.
• 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

• Background in civil engineering or familiarity with AEC workflows (CAD/BIM, 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 applied AI, building both the everyday tools engineers rely on and the more ambitious AI-powered systems.
• Strategic transformation opportunity: You will help define how a 10,000-person engineering firm builds, adopts, and scales internal software, including how AI gets woven into engineering practice.
• High ownership: You will shape architecture, influence priorities, and see your work in active use end-to-end.
