Job Description:

Looking for an opportunity to make an impact?

We are seeking a Computational Fluid Dynamics (CFD) Software Engineer to join our team in Morgantown, WV.  The position will be a hybrid of on site and remote research and development support for the NETL R&D facility in Morgantown, WV. This work will involve a multi-disciplinary, scientific, and technically-oriented national laboratory team, participation alongside other data scientists, engineers, geologists, and computer scientists that produces technological solutions for America’s energy challenges. From developing creative innovations and efficient energy systems, to advancing technologies that enhance oil and natural gas extraction and transmission processes, NETL research is providing breakthroughs and discoveries that support home-grown energy initiatives, stimulate a growing economy, and improve the health, safety, and security of all Americans. Highly skilled women and men at NETL’s three research sites – Albany, Oregon; Morgantown, West Virginia, and Pittsburgh, Pennsylvania – conduct a broad range of research activities that support DOE’s mission to advance the national, economic, and energy security of the United States. We are seeking a CFD Software Engineer interested in joining a distributed, multidisciplinary team working on the cutting edge of high-performance computing (HPC) and multiphase flow modeling. This work specifically supports MFIX-Exa, an energy application in the US DOE’s Exascale Computing Project.  MFIX-Exa is a coupled computational fluid dynamics and discrete element method (CFD-DEM) code developed on the AMReX software framework ( The high-performance code is massively scalable, performance portable and designed to utilize the largest supercomputers in the DOE’s fleet. The challenge problem which MFIX-Exa is tasked with simulating is NETL’s 50kW chemical looping reactor which will require tracking billions of particles and solving all relevant physicochemical phenomena. In this exciting role, you will support the MFIX-Exa project just as the code is being deployed at a new scale of leadership class computing.

Hybrid Schedule: Approximately 25% onsite and 75% working from home.

Come join the Leidos Research Support Team supporting the National Energy Technology Laboratory (NETL), where you’ll be able to work side by side conducting research with world-class scientists and engineers using state of the art equipment to contribute to new areas of basic and applied research; discover, integrate, and mature technology solutions to enhance the nation’s energy foundation and protect the environment for future generations. You will contribute to the development of patents, written reports, journal articles, and contribute to presentations on findings, highlights, and innovative solutions in DOE-sanctioned meetings, scientific conferences, and national committees.
