To our valued Leidos candidates:

Coronavirus is on everyone's mind with the effects being felt around the world. The markets are volatile, and we're all concerned for the health and safety of our families, friends, and colleagues. Please know that we're taking all necessary measures to safeguard our employees, customers and the communities in which we live, including following all recommended best practices around social distancing.

With that in mind, in an abundance of caution, we are canceling all face to face career events, such as job fairs and open house events. In the coming days and weeks, we will be hosting career events virtually, using our online chat tools so that we may continue our hiring practice safely and securely. You can find available virtual career events at

We are using telephone meetings and online chats via Brazen to conduct interviews and hiring discussions, and we are offering options for video interviews so that you can have a virtual face to face meeting with your potential new leader. We do not conduct interviews or extend offers via text or chat based social media, such as WhatsApp or MySpace.

Leidos will never ask you to provide payment-related information at any part of the employment application process, nor will Leidos ever advance money as part of the hiring process. And Leidos will communicate with you only through emails that are generated by automated system. If you receive an email purporting to be from Leidos that asks for payment-related information or any other personal information, please report the email to Chris Scalia, Leidos’ Senior Vice President of Talent Acquisition, at [email protected].

As a company, as a country, as a world, we have confronted challenging moments before. We are confident that, guided by our values and the strength of our community as well as the commitment we have to the important work we do each day, we will find our way through this time together. We will do this with the care and concern for one another and the common good that defines. Please keep those impacted by the virus in your thoughts.

Job Description:

Looking for an opportunity to make an impact?

Leidos is seeking a Multiphase Computational Engineer to join our research support team at the US Department of Energy National Energy Technology Laboratory (NETL) in Morgantown, WV.

The successful candidate will support collaborative research for modeling of energy technologies that often encompass pyrolysis, combustion, and gasification.  Current research initiatives involve carbon capture through polymeric reaction, hydrogen storage, and upgrading of biomass and municipal solid waste for potential use as fuel.  Other research relates to high-performance coal-based and natural gas-based energy systems. Duties include the development and application of advanced modeling tools and techniques to design and optimize the performance of carbon and hydrogen capture techniques as well as advanced energy and related systems based on biomass, municipal solid waste, coal, natural gas, and other fuels.

Work performed is primarily directed toward mathematical and computational modeling, as well as software development, as it relates to advanced energy systems. This work will emphasize application of computational fluid dynamics (CFD) to novel multiphase flow reactors and devices including circulating fluidized beds, fixed beds, particle classifiers, catalytic reactors, and other advanced energy systems. In-house simulation will emphasize NETL’s MFiX modeling suite, which includes Two-Fluid (TFM), discrete element (DEM), coarse-grained discrete element (CG-DEM), and Particle-in-Cell (PIC) models. The incumbent will work closely with NETL multiphase flow computational scientists to assist them with detailed code applications, development, and validation studies.  Work assignments will be in support of the NETL Computational Device Engineering Team and Multiphase Flow Science program in the Research & Innovation Center (CDE-RIC). 

If this sounds like the kind of environment where you can thrive, keep reading!

Primary Responsibilities:

  • Provide R&D technical support for the NETL multiphase flow sciences program.
  • Conduct mathematical modeling of energy systems and actively participate in software development.
  • Collaborate closely with multiphase flow science program members and create numerical /analytical /computational studies of advanced energy conversion systems. Apply experimental data to model validation and improvement efforts.
  • Develop high fidelity analytical and computational models of steady state and dynamic flows that exist in advanced energy conversion systems.
  • Analyze experimental data from laboratory tests and published data from other authors.
  • Present ideas and results to the research team. 
  • Contribute to future research planning and assist with proposals.
  • Work independently and collaboratively with members of the research team to meet milestones and deliverables.
  • Assist or lead efforts in writing research papers and creating conference presentations.

Basic Qualifications

  • Ph.D. in chemical engineering, mechanical engineering, or a closely related field
  • 0-1 years’ experience computational multiphase fluid dynamics research involving reacting multiphase fluid dynamics in gas-solids, gas-liquids, liquid-solids, three-phase reacting flows, numerical analysis, and mathematical modeling.

Preferred Qualifications

  • 1-3 years of postgraduate research and development experience in computational, mathematical and analytical model development relevant to fossil and/or biomass energy conversion and chemical process systems. Emphasis on computational multiphase flow with experience in development and application of Lagrangian and Two-Fluid Modeling approaches.  Familiarity with upgrading of biomass pyrolysis gas through catalytic processes and computational modeling of these systems is desired.
  • Ability to develop and apply complex multiphase computational fluid dynamics codes to study multiphase systems, including fluidized beds and other configurations important to energy conversion and chemical reactors. Experience using the NETL MFiX Software Suite to study these multiphase flow systems is highly valued.
  • Experience in scientific code development and application with an emphasis on creating computational models to aid in the design, understanding and analysis of complex multiphase flow systems, including Discrete Element Methods, Two-Fluid Modeling, and Kinetic Theory of Granular Flow approaches.
  • Familiarity with upgrading of biomass pyrolysis gas through catalytic processes and computational modeling of these systems is desired.  Knowledge of bioreactor systems including simulation of reactor performance will be helpful.
  • Experience in CFD modeling of chemical process reactors such as polymerization reactors is desired.
  • Experience with CFD software including FLUENT, OpenFOAM, MFiX, and COMSOL as well as Parallel Programming with C/C++, Fortran, Large-scale simulations on High Performance Computing facilities will be useful.  Experience in mesh generation (GAMBIT, ICEM-CFD), data collection and analysis (Tecplot, Paraview) are also valued.
  • Experience using ML/AI techniques is also a plus.
