120 Numerical Weather and Earth System Prediction Developer

The Cooperative Institute for Research in the Atmosphere at Colorado State University is a multi-million-dollar research organization located on CSU’s Foothills Campus in Fort Collins, Colorado. CIRA is a cooperative institute that is also a research department within CSU’s College of Engineering, in partnership with the Department of Atmospheric Science. Its vision is to conduct interdisciplinary research in the atmospheric sciences by entraining skills beyond the meteorological disciplines, exploiting advances in engineering and computer science, facilitating transitional activity between pure and applied research, leveraging both national and international resources and partnerships, and assisting the National Oceanic and Atmospheric Administration, CSU, the State of Colorado, and the Nation through the application of our research to areas of societal benefit. NOAA’s Global Systems Laboratory is a federal science and research laboratory under NOAA’s Office of Oceanic and Atmospheric Research. GSL provides the National Weather Service (NWS) and the nation with environmental observation, prediction, computer, visualization, and information systems. These systems deliver data, forecasts, and predictions of weather, including severe weather events, within the next few minutes to weeks away. GSL is a leader in the applied research, directed development, and technology transfer of environmental data, models, products, and services that enhance environmental understanding with the outcome of supporting commerce, protecting life and property, and promoting a scientifically literate public., The individual in this position will be a technical lead for numerical weather and Earth system prediction model development in the context of NOAA’s Unified Forecast System (UFS) leveraging the Model for Prediction Across Scales (MPAS) atmospheric dynamical core. They will lead and assist the implementation of new and revised modeling capabilities, infrastructure, and workflows. A particular focus will be on porting modeling system codes to future NOAA research, development, and operational cloud-computing architectures. The individual in this position will also play a leading role in optimizing modeling system components to improve their computational efficiency while maintaining their scientific robustness and in managing the code bases for which GSL - and specifically Physics branch members - are the lead developers and maintainers. This position will report to the Ensemble Prediction Scientist. Full Consideration Date: Monday, 9/28/2026, 11:59 pm (MT) Essential Job Duties:
