Key Responsibilities

In this role, you will provide technical leadership and work in collaborative small team environments to conduct research and analysis, develop models and scenarios, and perform analysis of a wide variety of system types across multiple domains (friendly and adversary; ground, air and space) to drive the development of clean-sheet requirements, refine existing program system requirements, and influence the pursuit of future technologies and capabilities.

You will work with air vehicle and subsystem engineers, as well as with program and customer leadership, to recommend candidate designs, and to develop Concepts of Operation, Tactics, Techniques and Procedures at the system, mission, and campaign levels. You will be responsible for developing new or integrating existing system simulation frameworks, performance models and algorithms, threat models and command and control models.

In this role you will be expected to thrive in a fast-paced work environment with high expectations, significantly diverse assignments, and collaborative/team settings across all levels.
