The Electronic Warfare Division has an opening for a Principal Level Computational Fluid Dynamic Engineer to work in Shalimar, FL.

This is a technical engineering position performing computational fluid dynamics modeling and simulation for hypersonic flows considering chemical and possibly thermal non-equilibrium effects.  The candidate will perform gridding, computational fluid dynamics simulations, gas dynamics calculations, flow visualization, and workflow programming, using both local and DoD Distributed Supercomputing Resource Centers for massive deployment and monitoring of solutions and harvesting of results.  These solutions will be interfaced with computational structural dynamics models to advance research in fluid-thermal-structural interactions (FTSI) of high speed missiles.



Complexity:   develop highly innovative solutions to complex computational fluid dynamics problems thru research and integration of best practices.  Employ ingenuity and creativity to integrate advanced computational fluid dynamic models with computational structural dynamics models to develop new approaches to FTSI research and achieve customer performance objectives.

Communication:  Must communicate with Leidos airframe research and guidance and control personnel, and interact daily with customer program leadership and team members and end users.   Must develop a clear understanding of customer goals and objectives; shape work to achieve those goals; and introduce new concepts, practices, and approaches.   Must present both verbal and written status on a regular basis, and prepare manuscripts for publication at technical conferences and for professional journals.    

Knowledge:  Demonstrate domain knowledge of high temperature gas dynamics, with solid numerical modeling skills.  Experience with computational fluid dynamic models such as Kestrel, FUN3D, US3D or equivalent is required.   Knowledge of chemical equilibrium and non-equilibrium modeling, and thermal equilibrium and non-equilibrium modeling is required.  Knowledge of how to perform automated gridding of complex aerodynamically controlled vehicles, including articulating control surfaces, and overset grids, is required.  Ability to utilize DoD DSRC capabilities is required.    

Education:  Requires a Master’s or Ph.D. degree in Aerospace, Mechanical or similar discipline and more than 12 years’ experience. 

Clearance:  Must be a U.S. Citizen with active Secret clearance. 

Desired Knowledge


Demonstrated experience with fluid-thermal-structural interaction and/or experience with US3D CFD model are highly desired.  Knowledge of workflow process tools such as Dakota and Galaxy Simulation Builder software.
