Job description

We have an opening for a Senior Software Engineer specializing in C#/.NET, with 8+ years of experience graphics programming, and Windows desktop application development. The successful candidate will be part of our Software Development Team and assist in maintaining, enhancing, and developing creating new features for our desktop application (StormWiseTM StormWiseTM), working closely with our software engineers and subject-matter experts. The candidate's initial primary focus will be learning and supporting the architecture of the existing codebase. Ultimately, the candidate will be tasked with optimizing the existing codebase and developing new features and enhancements. 

Streamline Technologies Inc. is a software development firm located in the Orlando,FL area, specializing in water resources engineering applications and flood forecasting.

Our philosophy and reputation are built on providing innovative software solutions such as the widely used hydrodynamic stormwater model, StormWiseTM (formerly ICPR ®), and our flood forecasting technology, FloodWiseTM.

Our water resources and flood forecasting applications include complex physics-based mathematical models that simulate the rainfall-runoff process, natural & man-made drainage system hydraulics, groundwater flow, water quality, and green stormwater infrastructure. Our applications center around a geospatial graphical interface that utilizes aerial imagery, thematic-based polygons, and digital elevation models. 

#LI-onsite


  • Own and evolve the geospatial rendering engine, the cartographic display layer that visualizes aerial imagery, thematic polygon layers, terrain surfaces, and drainage networks within our desktop platform 
  • Build, maintain, and enhance the drawing and editing tools that engineers use to create, modify, and inspect hydraulic/hydrologic model geometry directly on the map 
  • Implement and optimize 2D/3D rendering pipelines using DirectX (raster tiles, vector overlays, TINs, contour surfaces) 
  • Develop computational geometry algorithms for spatial operations such as polygon intersection, triangulation, coordinate transformations, and surface interpolation 
  • Integrate geospatial data formats and coordinate systems (shapefiles, geodatabases, raster formats) 
  • Collaborate directly with subject-matter experts to optimize the existing codebase and develop new features and enhancements. 
  • Participate in code reviews, technical documentation, unit testing, and continuous improvement of engineering practices 
  • Mentor junior staff and assist with the technical direction of our platform 

Required Skills 

  • Strong proficiency in C# / .NET development (Framework 4.8+, WinForms) 
  • Experience with DirectX, OpenGL, or a comparable graphics API for custom 2D/3D rendering (not just consuming a charting library) 
  • Strong background in vector and raster display technologies,  - built or substantially extended a mapping, GIS/CAD, or geospatial visualization layer 
  • Strong background in geometry and linear algebra as applied to graphics or GIS (projections, transformations, spatial indexing) 
  • Experience with programming vector and raster display technologies 
  • Experience with Git, branching strategies, CI/CD pipelines, and modern software engineering best practices 
  • Ability to communicate complex technical concepts clearly to cross-functional and non-technical stakeholders 
  • Experience with GDAL, SlimDX, or SharpDX 
  • Strong debugging skills using Visual Studio, VS Code, and diagnostic tools 

Preferred but required 

  • Familiarity with GIS concepts and processes — coordinate reference systems, map projections, spatial databases, and geoprocessing 
  • General knowledge of ArcGIS, QGIS, Global Mapper, <
