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 is currently seeking a Sr. Principal Engineer Systems – Level 4 to join our team at our Palm Beach Gardens, Florida and Elkton, Maryland locations to support the Propulsion Systems and Controls (PS&C) business unit.

In this role you will be working to support our Propulsion Systems & Controls Business Unit in developing the systems architecture to develop propulsion hardware such as valves, solid rocket motors, scramjets, ramjets, and thrusters for launch vehicles, missile systems, and space missions.

Our programs offer a unique experience to Systems Engineers, as you will get to experience the full Lifecyle development process from preliminary design to final test and delivery. We work with many customers from the Navy to the Air Force, as well as multiple private industry partners. The job will require the blending of Systems Engineering Principles and their application to hardware development programs at the subsystem level.
