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.

As a GNC Engineer – Level 3 or Level 4 located in Chandler, AZ
, your role will be pivotal in supporting missions critical to national and global security. This position is 100% onsite and cannot accommodate telecommute work. 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.

• 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.
• Other duties as assigned.

• Bachelor’s degree with 5 years of professional experience – OR – Master’s degree with 3 years of professional experience – OR – PhD with 1 year of professional experience. Will consider an additional 4+ years of experience in lieu of degree.
• Must have the ability to obtain and maintain a U.S. Government DoD Secret security clearance.
• Experience performing performance analysis on large data sets using data‑analytics and statistical‑analysis techniques.
• Proficiency creating and maintaining analysis tools in C++, MATLAB, and Python.
• Strong C++ development skills in a Linux environment.
• Proficiency with MATLAB and Python tool chains.

• Bachelor’s degree with 8 years of professional experience – OR – Master’s degree with 6 years of professional…
