The successful candidate will be part of our Software Development Team and will assist in maintaining, enhancing, and creating new features for our cloud-based SaaS platform and desktop application, working closely with our Software Engineers and the Water Resources Engineering Team. The candidate's initial primary focus will be learning and supporting the architecture of the existing codebase. Ultimately, the candidate will be optimizing the existing system and adding new features.

Streamline Technologies Inc. is a software development firm located in the Orlando area of Central Florida specializing in water resources engineering applications. Our philosophy and reputation are built on providing innovative software solutions such as the widely used hydrodynamic stormwater model, StormWise (formerly ICPR ). Our stormwater and flood forecasting models include complex mathematical models that simulate the rainfall-runoff process, drainage systems, flooding and flood forecasting, groundwater flow, water quality impacts, and green stormwater infrastructure. Our applications center around a geospatial graphical interface that utilizes aerial imagery, thematic-based polygon map layers, and terrain surfaces.

We pride ourselves on hiring the best and brightest in our field. At Streamline, we work in an atmosphere of cooperation and mutual respect, and as a company, we embrace a high standard of both external and internal accountability. We value safety, integrity, quality service, business success, and most importantly, our employees.
