Full Job Description

ABOUT MACH INDUSTRIES Founded in 2022, Mach Industries is a rapidly growing defense technology company focused on developing next-generation autonomous defense platforms. At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 220 employees, we operate with startup agility and ambition. Our vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security. THE ROLE Mach Industries is seeking a GNC Engineer, Modeling & Simulation to design, build, and maintain high-fidelity aircraft simulation environments in support of Guidance, Navigation, and Control (GNC) development. You will be responsible for realizing equations of motion in software, developing and validating aerodynamic and plant models, and creating the simulation infrastructure required for both software-in-the-loop (SITL) and hardware-in-the-loop (HITL) testing. This role is ideal for an engineer who thrives at the intersection of physics-based modeling, software development, and systems integration. You’ll collaborate closely with aerodynamicists, controls engineers, and hardware teams to ensure Mach’s autonomous platforms are accurately modeled and rigorously tested before flight. KEY RESPONSIBILITIES - Develop and maintain high-fidelity flight dynamics and vehicle simulation models. - Implement equations of motion in C++ and Python for real-time and offline simulation environments. - Collaborate with the aerodynamics team to incorporate aerodynamic models derived from CFD and wind tunnel testing. - Perform system identification and parameter estimation to generate accurate plant models. - Build and sustain simulation infrastructure supporting
