As a Senior Modeling & Simulation (M&S) Engineer , you will develop models, tools, and simulations of next-generation space systems. The products you develop will form the backbone of a high-performance space systems team, aligning
requirements and specifications from early mission analysis through spacecraft design, manufacturing, and in-space operations. You will work with subject matter experts across space systems engineering, flight software, manufacturing, and mission operations to continuously improve systems models and digital twins. Applying modern software development practices and technology, you will deliver scalable solutions which enable rapid mission analysis and superior technical decision making. You will be a force-multiplier within the Solutions Architecture team, empowering the rapid development and deployment of next-generation spacecraft, high-speed optical communications networks, and space technology. The ideal candidate possesses experience developing high-quality, scalable software systems within a small cross-functional team. They enjoy learning from subject matter experts across a broad range of technical domains, and can distill complex systems concepts into concise, elegant solutions. They love to experiment, prototype, and use new tools and technology (including AI) to learn, grow, and improve. Success in this role requires creativity, curiosity, pragmatism, and collaboration. \n Key
