Responsibilities

The Modeling, Simulation & Analysis Intern will work within a multi-discipline team (e.g. Guidance, Navigation, and Control, Signal Processing, Mechanical Design) to design and develop differing levels of fidelity simulation models which represent the components of a system

This includes the ability to read, debug, edit and create computer programming code to enhance simulation models, creating and executing unit tests on the models to verify functionality, documenting the design and test results, and integrating with other component models in a complex system simulation environment

The MSA Intern will support simulations in a high-performance computing environment, which can include the use of Graphics Processing Units, to support missile system design/trade studies, performance assessment, and system test

This Engineer will work within a team to develop analysis of the data for the specific task as well as provide insight and understanding of the system performance, recognizing and troubleshooting any anomalies observed in the simulation results

The MSA Intern will support the solutions provided to meet their defined requirements and function as needed through rigorous verification and validation

This activity utilizes data from multiple sources up to and including system level flight testing
