Groundwater Modeling Remote Jobs (NOW HIRING)

We are seeking a senior Postdoctoral Research Associate to join our interdisciplinary research team at ExxonMobil Biomedical Sciences, Inc. (EMBSI). The Associate will support and lead a diverse portfolio of applied research projects aimed at evaluating the role of water management in enhancing ecosystem resilience, hydrologic function, and biodiversity across a range of ecosystems. Serving as a cross-disciplinary scientific integrator, the candidate will provide leadership in study design, QA/QC oversight, and technical coordination across hydrologic modeling, hydrogeologic systems, ecological monitoring, and geospatial analytics. This role emphasizes ensuring scientific defensibility, data integrity, and alignment across complex datasets and modeling systems, while synthesizing outputs to inform adaptive management and decision-making.

In addition to coordinating ongoing efforts, the Associate will actively generate novel research directions by translating integrated data insights into new hypotheses, study designs, and strategic initiatives. The position requires close collaboration with a broad team of industry, academic scientists, and 3rd party collaborators to co-develop approaches, harmonize methodologies, and integrate expertise across disciplines. Through these efforts, the candidate will contribute to high-impact research, proposal development, and partnerships with academic and industry collaborators, advancing our understanding of the water, soil, plant, animal nexus, including surface-groundwater interactions. In addition, postdoctoral researchers are encouraged to publish and present their work in peer-reviewed journals and conferences. This is supported through a standard internal review process designed to protect intellectual property and confidential business information while enabling timely dissemination of scientific results.

This opportunity is for a postdoctoral position expected to last one to three years, subject to annual review and renewal.
