Job description

Overview
Join our Indoor GIS team and help shape the future of how people understand, navigate, and interact with the built environment. We are building AI-powered capabilities that bring intelligence to indoor spaces, extracting meaning from 3D scans, floor plans, imagery, and spatial data to automate workflows and unlock new possibilities for our customers.
This role sits at the intersection of computer vision, AI/ML, 3D graphics, and geospatial software. Depending on the problem, your work may span applied research and prototyping, production engineering, or integration with other Esri teams. You will help define what's possible and figure out the best path to get there.
If you are energized by ambiguous, high-impact problems and want to work across a wide technology surface, from LLMs and Gaussian Splatting to image processing and semantic search, this team offers a uniquely broad and forward-looking challenge.
Esri has a Relocation Assistance Program and can provide support with relocating to the Redlands, CA area for this position.
Responsibilities
Research, prototype, and develop AI-powered features across a diverse problem space, including:
  • Develop software components and tools for indoor feature extraction, Gaussian Splatting, PDF floor plan extraction, indoor reality workflows, and AI-assisted validation
  • Prototype and integrate algorithms for image/video analysis, geometric calculations and transformations, model evaluation, semantic search, and visual positioning under guidance from senior engineers
  • Write clean C++, .NET/C#, and Python code to process spatial data, imagery, video frames, floor plan geometry, and user-reviewed AI/ML outputs
  • Contribute to experiments with LLMs, computer vision models, embeddings/vector search, and AI coding workflows, documenting results and limitations clearly
  • Collaborate with cross-functional engineering and product teams across Esri
  • Participate in code reviews and software quality processes
  • Learn and apply GIS concepts, floor-aware mapping patterns, ArcGIS data models, and indoor facility workflows to ensure features solve real user problems
  • Present prototypes, demos, and findings to the team and incorporate feedback into iterative development
  • Participate as an individual contributor to a Scrum software development team

Requirements
  • 2+ years of professional software development experience
  • Proficiency in Python and working knowledge of C++ or .NET/C#; willingness to deepen expertise in all three as required by product work
  • Experience prototyping or integrating AI/ML technologies into real software
  • Strong understanding of software algorithms and data structures
  • Familiarity with image analysis, computer vision, or 3D/graphics programming
  • Experience working with APIs and services
  • Strong analytical, problem-solving, and communication skills
  • Experience or exposure using AI to assist in code development (Copilot or spec driven development with an LLM like Claude, Codex, or similar)
  • Bachelor's degree in Computer Science, Software Engineering, or a related STEM field

Recommended Qualifications
  • Experience with OpenCV, ONNX, image/video feature extraction, object detection, segmentation, or model evaluation
  • Exposure to Gaussian splats, 3D mesh processing, graphics programming, game engines, WebGL/OpenGL/DirectX, or reality capture workflows
  • Familiarity with GIS concepts, ArcGIS, CAD/BIM/Revit, LiDAR, 360 imagery, indoor positioning, or indoor mapping workflows
  • Experience with semantic search, embeddings, vector databases, RAG, LLM APIs, Claude/ChatGPT/Gemini/Llama, or AI-assisted coding tools such as GitHub Copilot/Copilot Chat
  • Experience creating clear technical specs, unit tests, benchmark scripts, data analysis notebooks, or prototype documentation
  • Master's degree or advanced coursework in Computer Science, AI/ML, Computer Vision, Graphics, Robotics, GIS Science, or a related STEM field
