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. If forging a secure future excites you, look no further! Northrop Grumman’s Space Sector provides an arena where your passion for innovation and quest for exploration are welcome. As a GNC Engineer – Level 3 or Level 4 your role at Chandler, AZ will be pivotal in supporting missions critical to national and global security. This position is 100% onsite and cannot accommodate telecommute work. Ready to join forces with our visionary team? The GPI Program designs, develops, and validates algorithms, software, and simulation tools that provide precision guidance, navigation, and control for aircraft, spacecraft, missiles, launch vehicles, and marine platforms throughout all mission phases—from powered ascent and coast to orbital insertion and interplanetary cruise. It processes sensor data statistically to feed realistic navigation models, formulates equations to achieve desired positions, orientations, or orbits, and creates control laws together with the necessary hardware and software specifications. Rigorous verification and testing ensure reliable performance during launch, staging events, and sustained operations in diverse environments. This position will work a 9/80 schedule, with every other Friday off. In this job, you will: Design, develop, implement, verify, and test algorithms, software, and simulation tools that enable guidance, navigation, and control (GNC) for aircraft, spacecraft, submersibles, surface ships, missiles, launch vehicles, and upper stages throughout all mission phases (powered ascent, coast, flight, Earth orbit, interplanetary cruise, orbital insertion, and staging events). Perform statistical processing of measured sensor data and integrate the results into algorithms that simulate physical reality for navigation functions. Formulate and implement the equations required to achieve specific positions, orientations, or orbital trajectories as part of the guidance function. Develop control laws and define hardware and software requirements for control‑design and analysis of aircraft, launch vehicles, and spacecraft. Conduct comprehensive verification and testing, including unit, integration, hardware‑in‑the‑loop (HIL), and flight‑representative simulations, to ensure compliance with mission performance and safety standards. Document all design decisions, test plans, results, and compliance evidence in accordance with aerospace software standards (e.g., DO‑178C, ECSS). Collaborate with cross‑functional teams—systems engineering, flight operations, and hardware engineering—to align GNC solutions with overall vehicle architecture and mission objectives.
