Job Description:
The Electronic Warfare Division at Leidos has an opening for a Lead Fluid-Thermal-Structures Interaction (FTSI) engineer at Eglin AFB.

This is a technical engineering position to develop fluid-thermal-structural interaction models for high speed missile systems. Work directly with the organizations developing the most advanced weapons systems in the world in the high profile area of hypersonic weapons systems. The Aerophysics group operates in a small team environment where individual creativity is rewarded and continuous learning is the norm. The Destin-Fort Walton Beach-Niceville area is home to world famous beaches and a relaxed 'salt-life' lifestyle.

Apply and develop multi-fidelity computational fluid dynamics, structural dynamics and thermal models of high speed weapons systems. Develop and apply cutting edge coupling methodologies to achieve an FTSI modeling capability in tractable engineering timelines to enable better understanding of the complex interactions on hypersonic weapons systems. Leverage these results to create fast running (orders of magnitude faster than first principle) models for real-time applications; create surrogate models for calculations of fluid-thermal-structural interactions coupling. Develop efficient run/test matrices to minimize the number of required computations and thus enable the evaluation of multiple high speed vehicle designs.

Complexity: develop innovative solutions for complex fluid-thermal-structural interactions problems thru research and integration of best practices. Employ ingenuity and creativity to integrate advanced coupling 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, 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.

Required Knowledge: Experience with one of the following disciplines is required:

Computational fluid dynamics for supersonic / hypersonic flows

Computational structural and thermal modeling using Finite element models

Reduced Order models, including Design of Experiments (DOE), Kriging, Co-Kriging, Proper Orthogonal Decomposition (POD), radial basis functions (RBF), Surrogate Response Surfaces (SRS), near-orthogonal Latin hypercubes, and other methods.

Knowledge of optimization schemes.

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.

Experience with multiple software languages (Fortran, C++, Matlab, Python, etc.) is required.

Education: Requires a Master's degree in Aerospace or Mechanical Engineer, Mathematics, or similar discipline. Master's candidates require 4+ years' experience.

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

Desired Knowledge: Familiarity with Dakota systems analysis software. Experience with aerodynamics models a plus. Familiarity with Neural Network and Support Vector Machine tools (SUMO or other) is desired.

TRAVEL: Attend technical reviews and professional conferences, estimated
