Sr Staff Software Engineer

RELOCATION ASSISTANCE: Relocation assistance may be availableCLEARANCE TYPE: SecretTRAVEL: Yes, 10% of the Time 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.Designs, develops, implements, verifies and tests algorithms and software and simulation tools to perform guidance, navigation and control of aircraft, spacecraft, submersibles, surface ships, missiles, launch vehicles and upper stages during powered and coast phases of launch, flight, earth orbit, interplanetary cruise and orbital insertion, as well as during staging events. Navigation functions include the statistical processing of measured data points and their substitution into algorithms simulating physical reality. Guidance functions include the formulation of specific equations to achieve a desired position, orientation or orbit in space. Control design and analyses processes consist of the development of the control laws and hardware and software requirements for aircraft, launch vehicles and/or spacecraft.
