Data Scientist

At PNNL, our core capabilities are divided among major departments that we refer to as Directorates within the Lab, focused on a specific area of scientific research or other function, with its own leadership team and dedicated budget.

Our Science & Technology directorates include National Security, Earth and Biological Sciences, Physical and Computational Sciences, and Energy and Environment. In addition, we have an Environmental Molecular Sciences Laboratory, a Department of Energy, Office of Science user facility housed on the PNNL campus.

The Energy and Environment Directoratedeliversscience and technology solutions for the nation’s biggest energy and environmental challenges. Our more than 1,700 staff support the Department of Energy (DOE), delivering on key DOE mission areas including: modernizing our nation’s power grid to maintain a reliable, affordable, secure, and resilient electricity delivery infrastructure; research, development, validation, and effective utilization of renewable energy and efficiency technologies that improve the affordability, reliability, resiliency, and security of the American energy system;

and resolving complex issues in nuclear science, energy, and environmental management.

The Earth Systems Science Division, part of the Energy and Environment Directorate, provides leadership and solutions that advance Earth system opportunities for energy systems and national security. We are a multidisciplinary division connected by a shared commitment to innovate and collaborate towards solving complex problems in the dynamic Earth system.

PNNL’s Environmental Subsurface Science Group is seeking a mid-level scientist or engineer with expertise developing PFLOTRAN to lead and contribute to projects modeling subsurface reactive multiphase flow for problem scenarios including geologic carbon storage, geothermal energy production, and environmental remediation. The position requires the ability to lead and support development of simulation capabilities and application of advanced simulation tools to diverse problems.

The candidate will lead and work collaboratively with teams in multiple disciplines including geophysics, geochemistry, and environmental engineering.
