OverviewWe 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 developcreating 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.
