At Northrop Grumman, our employees have incredible opportunities to work on revolutionary systems that impact people's lives around the world today, and for generations to come. Our pioneering and inventive spirit has enabled us to be at the forefront of many technological advancements in our nation's history - from the first flight across the Atlantic Ocean, to stealth bombers, to landing on the moon. We look for people who have bold new ideas, courage and a pioneering spirit to join forces to invent the future, and have fun along the way. Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they're making history.

Northrop Grumman Aeronautics Systems has an opening for a Modeling Simulation and Analysis Engineer (Principal or Sr. Principal Level) to join our team of qualified, diverse individuals within our Systems Engineering organization. This role may be located in El Segundo, CA.

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 (CONOPs) and Tactics, Techniques and Procedures (TTPs) at the system, mission, and campaign levels.

You will be responsible for developing new and/or integrate 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, collaborative/team settings across all levels.
