Fluid-Thermal-Structures Interaction Engineer (637003)

  • 02/19/2018

Job Description


The Electronic Warfare Division has an opening for a Lead Level Fluid-Thermal-Structures Interaction (FTSI) engineer.

This is a technical engineering position to develop Reduced Order Models (ROMs) of fluid-thermal-structural interaction of high speed missile systems. Leverage results of first principles fluid, thermal, and structural dynamics modeling to create fast running (orders of magnitude faster than first principle) models for real-time applications; create surrogate models for speed calculations of fluid-thermal-structural interactions coupling. Develop efficient run/test matrices to minimize the number of required computations.


Complexity: develop innovative solutions to complex fluid-thermal-structural interactions problems thru research and integration of best practices. Employ ingenuity and creativity to integrate advanced reduced order models to develop solutions that achieve customer performance objectives.

Communication: Must communicate with Leidos aerodynamics, airframe, and guidance and control personnel, and interact daily with customers and team members and end users. Must develop a clear understanding of customer goals and objectives and shape work activities to satisfy them. Must present both verbal and written status on a regular basis, and prepare manuscripts for publication at technical conferences and for professional journals.

Knowledge: Experience with Design of Experiments (DOE), Kriging, Co-Kriging, Proper Orthogonal Decomposition (POD), radial basis function (RBF), Surrogate Response Surfaces (SRS) and other methods is required. Knowledge of optimization schemes is required. Ability to manipulate “big data” sets and reduce the size of aerodynamic, structural, and thermal knowledge among computational tools is essential. Ability to utilize DoD DSRC capabilities is required.

Education: Requires a Master’s degree in Aerospace or Mechanical Engineer, Mathematics, or similar discipline. Master’s candidates require gt; 2 years’ experience.

Clearance: Must be a U.S. Citizen with active Secret clearance or able to achieve a Secret clearance.

Desired Knowledge

Familiarity with Dakota systems analysis software. Ability to utilize DoD DSRC capabilities. Experience with aerodynamics models a plus.

TRAVEL: Attend technical reviews and professional conferences, estimated lt; 10%.
