• assisting and executing the application of hydraulic and hydrologic riverine models to natural and urban watersheds;

• supporting water resource management studies,

• assisting in quantitative impact assessment studies related to our client’s operations in lacustrine, riverine, and marine environments;

• using geospatial data analytics, related software (ArcGIS or similar), calculations and models to address impact, regulatory and climate change issues; and

• acquiring and processing datasets, monitoring model applications, performing supporting calculations, and documenting results.

• Collaborating with modeling and engineering teams to develop, deploy, and maintain modeling tools on cloud platforms (e.g., Azure), including web-based or desktop interfaces for internal and client-facing applications.

• Supporting full-stack development needs, including integration of scientific computing models (e.g FORTRAN, VBA, Python, R), and frontend interface developments using Docker, Lambda or APIs.
