The Aeronautics Systems Survivability & Systems Engineering group is looking for a Systems Modeling and Simulation Engineer to help us shape the future of the sector, the company, and our customers. We work in conjunction with Northrop’s Strategy and Business Development organization to evaluate the performance of existing and candidate system designs in representative operational environments. Our work influences the investment decisions of our senior leadership and customer program offices. The Modeling and Simulation discipline draws from the skills and experience of many other (e.g. Systems Engineering, Aerospace Engineering, Electrical Engineering, Software Engineering, etc.) and frequently collaborates across diverse and functional disciplines, offering a unique opportunity to obtain a broad understanding of many areas or to more narrowly focus on developing a deep expertise in any of the contributing fields.

In this role, the selected candidate 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 (CONOPs) and Tactics, Techniques and Procedures (TTPs) at the system, mission, and campaign levels.

The selected candidate with be responsible for developing new and/or integrate existing system simulation frameworks, performance models and algorithms, threat models and command and control models.

Essential Functions:
