Job Description

## Position Description

The Johns Hopkins University Applied Physics Laboratory (APL), a national leader in scientific research and development, is located midway between Baltimore and Washington, DC. We are seeking a highly motivated, creative analyst to join a dynamic diverse group providing superior mechanical and aeronautical engineering services and products to address the hard challenges for programs of national importance.

**Job Summary:** Analyze and evaluate the thermal response and Electro-Optic/Infrared (EO/IR) signature of missiles, rocket motor plumes, wakes and trails in endo and exo-atmospheric flight conditions supporting ballistic missile defense technology development and other programs. Develop and extend innovative thermal and EO/IR numerical simulation capabilities for existing and new phenomenologies.

**Duties (Listed in order of importance with the estimated amount of time spent at each task):**

1. Create numerical models to predict EO/IR signature phenomenology's of missiles, rocket motor plumes, wakes, trails and the relevant background scenes in endo and exo-atmospheric flight conditions in support of ballistic missile defense technology development and other programs. (20%)

2. Aerothermal analyses of Thermal Protection System (TPS) composites exposed to thermo-chemical ablation and mechanical erosion at high temperatures. (20%)

3. Improve modeling of radiation thermal and EO/IR transport. (20%)

4. Develop and extend the analytical capabilities used for intensive numerical analyses and associated graphical applications using the LINUX operating system. (20%)

5. Compare predictions with wind tunnel, laboratory and flight test data and literature. (10%)

6. Document results in technical memorandum and publications, present findings to government agencies and professional societies. (10%)

**_Note: This job summary and listing of duties is for the purpose of describing the position and its essential functions at time of hire and may change over time._**
