The Propulsion team designs, develops, and qualifies engines that power Anduril's family of autonomous air vehicles. We take engines from concept through prototype, test, and into production on timelines measured in months. Our team operates at the intersection of high-performance rotating machinery, advanced manufacturing, and rapid flight test, delivering propulsion systems that are redefining what's possible for defense applications.You will work on engine development in a lean, high-ownership culture where you directly shape the product and operate at a velocity to test and fly new hardware within months, not years. ABOUT THE JOB Here you will work on core propulsion hardware development, including engine components, assemblies, and propulsion subsystems. The role requires high ownership and frequent collaboration with other core disciplines within the Propulsion team and across the broader vehicle programs. Ideal candidates are practical, hands-on, and self starters. WHAT YOU'LL DO Own and drive mechanical design and development of propulsion components and assemblies, overseeing the process from initial concept to low rate production. Lead technical efforts to define requirements, propose possible solutions, and establish a methodology for evaluating and verifying mechanical systems. Work in close partnership with other disciplines to ensure the electrical, software, and mechanical systems collectively form a reliable, flexible, cost-effective system. Spearhead design reviews, conduct analysis, visit vendors, prototype and implement hardware test plans. Actively contribute to the enhancement of team tools, templates, processes, and standards.
