Description

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.

Northrop Grumman’s Aeronautics Systems – Research & Advanced Design (R&AD) transforms breakthrough ideas into mission-ready capabilities through intelligent anticipation. We’re the front-end design engine, defining what comes next. From developing cutting-edge next-generation future aircraft to trailblazing collaborative autonomous platforms, we push the boundaries of technology and forge industry-leading partnerships that set new standards for what’s possible.

Our team owns the full lifecycle of advanced concept creation, from visionary early-stage designs and rapid prototyping to high-impact demonstrations and solving the toughest technical challenges in survivability, autonomy, and battle management. We seek curious, adaptable people who thrive on turning intuition into breakthrough solutions. If you’re driven to invent the future, build what’s next, and shape the landscape of national security, this is where you belong.

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.

Perform mission engineering activities to ensure continuity between desired operational capabilities and delivered system performance, through the Systems Engineering “V”. Ensure performance capabilities of new systems and architectures are traded against cost and mission requirements; develop operationally relevant mission scenarios; assess operational effectiveness of existing and emerging systems and capabilities in representative operational environments.
Solicit input from various stakeholders, synthesize data, and communicate results to various levels of leadership within the organization.
