Our employees are not only part of history, they're making history. Northrop Grumman Aeronautics Systems  has an opening for a  Systems Engineer (2/3 level) - Modeling Sim & Analysis Software Dev to join our team of qualified, diverse individuals within our Systems Engineering organization. This role is located in  Palmdale, CA . Roles and Responsibilities will include: Design, develop, integrate, and test physics‑based, real‑time engineering simulations supporting mission‑level Operator‑In‑The‑Loop (OITL) environments. Implement and maintain software components that model sensor/payload operations and advanced Electronic Warfare (EW) effects, using modern frameworks and object‑oriented programming languages (e.g., C#/C++, Java). Perform trade studies via computer simulation to compare architectures and recommend software and system design alternatives. Develop, integrate, and refine advanced graphical user interfaces and visualization tools to support operator interaction and mission analysis. Utilize software and analytical tools to model system behavior in real‑time and constructive simulations, focusing on robust, scalable, and maintainable code. Conduct software builds and installations, perform smoke tests, and drive automated/continuous integration test approaches to ensure software quality. Debug complex software issues, optimize performance, and enhance existing simulation capabilities based on test results and user feedback. Periodically demonstrate integrated software capabilities to sector leadership and key customers and incorporate feedback into the product roadmap. Collaborate within Integrated Product Teams (IPTs) to define requirements, design interfaces, and deliver integrated mission‑simulation solutions across multiple security environments, programs, and platforms.
