Post Doctorate RA - Computational Mechanical Engineer

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, Integrated Discovery 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 Nuclear Sciences Division part of the Energy and Environment Directorate, delivers science and technology innovations for the environment, energy, and national security. At a time when complex challenges are emerging on many fronts, we address some of the most challenging national and international nuclear issues. This includes providing technological solutions that protect the public health and safety around nuclear facilities, developing durable new materials for extreme nuclear environments, innovating new nuclear processes for the safety and security of the nation, and delivering new approaches for accelerating environmental cleanup of nuclear sites.

The division’s capabilities and efforts are focused on environmental management of nuclear sites, nuclear regulatory processes, national nuclear security, and advancing nuclear energy.

The Experimental and Computational Engineering Group explores and delivers engineered solutions based on expert analysis, experimentation, and computation. We are seeking a computational mechanical engineer post doc to join our group in support of complex nuclear challenges.
