## Description

Join BAE Systems and contribute to one of the most complex national-defense modernization efforts in the world. As a Principal MS&A Software Engineer, you will play a critical role in developing the digital architecture that underpins the next-generation LGM-35A Sentinel ICBM. Your work directly supports the U.S. Air Force by ensuring the missile system is safe, accurate, and mission-ready.
What You'll Do

In this role, you will lead the creation and refinement of a high-fidelity six-degrees-of-freedom (6-DOF) simulation model used to predict missile flight performance and validate vehicle design. Your responsibilities include:

 * Simulation Development: Design, code, and test advanced rocket and missile dynamics models to evaluate flight behavior and system performance.
 * Technical Validation: Apply advanced engineering principles to ensure MS&A tools are physically accurate, complete, and reliable.
 * Cross-Functional Collaboration: Work closely with propulsion, guidance, and systems engineering teams to assess solid rocket motors, guidance components, and propulsion systems.
 * Strategic Reporting: Convert complex simulation outputs into clear technical briefings and reports for the USAF System Program Office.
