Anduril Industries is a defense technology company transforming U.S. and allied military capabilities through advanced technology. The Maneuver Dominance team is building Thunder, an autonomous attack rotorcraft designed to fight alongside crewed combat aviation. Thunder is a compact airframe with weapons, sensors, and radios competing for limited antenna real estate while flying low and in formation in contested spectrum environments. As Senior Mass Properties Engineer, you will develop, track, and manage mass properties for air vehicles to meet design and performance criteria. You will translate configuration concepts and design requirements into accurate mass estimates, center of gravity (CG) data, and inertias. Your responsibilities include developing and maintaining detailed weight statements, performing mass distribution analyses, and assessing the impact of design changes on overall vehicle mass characteristics. Key responsibilities: - Contribute to development of mass properties (weight, CG, inertia) data for new air vehicle development - Develop, track, and manage mass properties data throughout air vehicle design phases - Participate in defining mass properties-related design requirements - Provide vehicle and subsystem configuration trade study guidance - Support vehicle and subsystem level weight and balance control efforts - Estimate, calculate, measure, and verify weight, balance, and inertia of components, assemblies, and completed vehicles or systems - Participate in developing and maintaining mass properties accounting systems - Generate mass properties reports - Participate in developing and implementing new processes and tools You will work on a compact, weapons-laden autonomous aircraft operating in contested spectrum—the antenna real estate and RF environment challenges are core to the problem you'd own. REQUIREMENTS: - Bachelor's degree in Aerospace Engineering, Mechanical Engineering, Robotics, Physics, or related technical discipline - 5+ years of experience in aircraft mass properties or related aerospace design roles - Strong understanding of aerospace principles, vehicle dynamics, and system integration - High ownership and bias toward action—if you see a problem, you want to fix it PREFERRED QUALIFICATIONS: - Proven track record leading aircraft mass properties efforts from early development through flight test and production - Experience with aircraft mass properties tools - Coding experience to build out complex databases to manage and process BOM and weights data - Experience with Formula SAE, Baja SAE, Design Build Fly, or similar competitive engineering programs demonstrating hands-on vehicle integration experience
