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. Please note that this opportunity is contingent on program funding. Start dates are determined after funding confirmation. At Northrop Grumman, we Define Possible. We are a passionate community of engineers and leaders, a creative community of scientists and researchers, a diverse community of human beings, all driven to pioneer the future. And in Survivability, that future is bright… Or, from the enemy’s perspective, it is as dark as the cover of a moonless night. Now, imagine sitting in a stadium, or outside at a parade, and the next generation of Stealth Technology flies overhead, drawing a roar of admiration from the crowd. Imagine being able to turn to the person next to you and saying “I had a hand in that.” At Northrop Grumman Aeronautics Systems and in Survivability Engineering, that could be Your Possible. We are tasked with developing, testing, and implementing new materials, technologies, and concepts, that enable the most lethal, intelligent, and collaborative systems to penetrate and operate in enemy airspace with impunity. We work hand in hand with a broad swath of other engineering disciplines to design, develop, manufacture, and sustain these systems. Our responsibilities span the full Systems Engineering lifecycle—from research and development to modeling and analysis, from static / component test to dynamic flight test, from manufacturing floor support to field repairs and maintenance, and more. We work across multiple spectrums—from RF (Radio Frequency) to IR (Infrared) and Visual, to Acoustic. Our engineers have the opportunity to work in various environments—behind desks, in highly specialized labs, at indoor and outdoor test and measurement ranges, and at overseas operational locations. Our team is absolutely critical to the cradle-to-grave success of our cornerstone programs and the programs of the future, and your role on our team would be equally critical to our success as an organization.
