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’s Space Sector is seeking a Guidance Navigation Control Engineer: Modeling and Simulation (M&S) Product Lead – Level 4/5 to join our team in Chandler, AZ. This position is 100% onsite and cannot accommodate telecommute work. Our GNC (Guidance, Navigation and Control) Engineers design, develop, implement, verify, and test algorithms and simulation tools that deliver guidance, navigation and control for aircraft, spacecraft, missiles, launch vehicles and related platforms across every mission phase—from powered ascent to interplanetary cruise and orbital insertion. In this job, you will be responsible for both the GNC technical modeling, simulation, and analysis as well as the Modeling and Simulation product lead responsibilities of IMS planning, team management/support, cross‑team coordination, as well as customer‑facing communication and facilitation of internal/external working groups. This position will work a 9/80 schedule, with every other Friday off. This position is contingent upon the candidate obtaining final clearances and program access(es) within a reasonable period of time as determined by the company. In This Job, You Will Design, develop, implement, verify, and test high‑quality software and simulation toolchains for missile flight systems. Develop and integrate autopilot and guidance algorithms directly into missile flight code. Seamlessly incorporate algorithms into the vehicle’s flight software while collaborating with software and hardware teams. Utilize various trajectory‑optimization tools to generate, interpret, and analyze vehicle trajectory results. Modify or create new scripts (e.g., Python, MATLAB, Bash) to capture customer requirements and measure vehicle performance. Build, validate, and maintain modeling and simulation frameworks for aerospace vehicles and components, ensuring accuracy across operational scenarios. Enhance simulation fidelity by integrating advanced modeling techniques to support system analysis and decision‑making. Conduct rigorous testing and evaluation of simulation models, identifying and resolving discrepancies between simulated and real‑world performance metrics. Gather, post‑process, and analyze large, complex data sets to verify and validate performance results. Ensure that simulation outcomes match intended performance metrics and system specifications. Document design rationale, test results, and compliance evidence for aerospace standards and program reviews. Collaborate with multidisciplinary engineering teams (systems, propulsion, structures, avionics) to integrate GNC solutions into overall vehicle architectures. Other duties as assigned. Basic Qualifications For Level 4 Bachelor’s degree with 8 years of professional experience – OR – Master’s degree with 6 years of professional experience – OR – PhD with 4 years of professional experience.
