Position Summary

RSI is recruiting for a Staff Hydrologist who will support the Groundwater Program for U.S. Department of Energy Office of Legacy Management projects. The scientist will assist with projects involving groundwater and contaminant characterization, conceptual site model development, long-term monitoring, and remedial design and performance evaluations. Groundwater Program scientists embrace innovation and cutting-edge methodologies and technologies and are recognized as industry leaders in 3-D visualization and evaluation, geochemical assessment, and groundwater flow and reactive transport modeling. Staff development is a program priority and is accomplished through mentoring and increasingly challenging technical assignments; conference attendance and journal publications are encouraged. The culture promotes work-life balance, where member needs and accomplishments from their personal and professional lives are strongly valued.

In addition, the Staff Hydrologist will support the LM Applied Studies and Technology (AS&T) Program and support data mining for groundwater applications and water balance data QC and calibration activities. Data mining is designed to support the LM mission through improved understanding of processes that affect remedy protectiveness and performance, including evaluation and application of advancements in technology. Ongoing AS&T studies include long-term disposal cell cover performance, plume persistence, enhanced natural attenuation, system operations and analysis at remote sites, data mining and project visualization and educational collaborations. AS&T studies are not limited to the ongoing studies; any study related to LM’s mission will be considered for inclusion in the program.

The ideal candidate will have a solid foundation in hydrogeologic and hydrologic principles, an understanding of groundwater and contaminant characterization methods, and strong skills in data analysis and reporting. Strong quantitative skills and experience with groundwater modeling tools, Python and R programming, and statistical analysis is preferred. This role requires a balance of technical expertise, fieldwork leadership, and project coordination, with opportunities for growth under the guidance of senior staff.
