Mechanical Engineer, Propulsion

Anduril Industries is a defense technology company with a mission to transform U.S. and allied military capabilities with advanced technology. By bringing the expertise, technology, and business model of the 21st century’s most innovative companies to the defense industry, Anduril is changing how military systems are designed, built and sold. Anduril’s family of systems is powered by Lattice OS, an AI-powered operating system that turns thousands of data streams into a realtime, 3D command and control center. As the world enters an era of strategic competition, Anduril is committed to bringing cutting-edge autonomy, AI, computer vision, sensor fusion, and networking technology to the military in months, not years. ABOUT THE TEAM Anduril is seeking a Mechanical Engineer to join the Propulsion Development team at our Santa Ana facility. 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. Balance operational needs across engine subsystems while optimizing for performance, mass, manufacturability, and cost. Support critical hardware demonstrations with customers as needed. Travel to test sites and vendors as needed. REQUIRED QUALIFICATIONS BS or MS in Mechanical Engineering 2+ years in a technical engineering role, or equivalent experience through student engineering teams (Formula SAE, Baja SAE, etc.), personal projects, or internships, demonstrating a high level of personal contribution Proven CAD skills and the ability to produce high-quality engineering models and drawings that comply with common industry standards. Strong understanding of engineering fundamentals in machine design, mechanisms, fluids, thermal, and structures Hands-on prototyping, fabrication, and assembly skills, including experience with shop tools, machining, and soldering Knowledge of manufacturing processes (CNC machining, 3D printing, castings, sheet metal, composites) and ability to design for manufacturability US Person status is required as this position needs to access export-controlled data. PREFERRED QUALIFICATIONS Hands-on experience with engine design, assembly, or testing (turbine, automotive, etc.) Solid understanding and application of GD&T, including tolerancing for high-speed rotating machinery Experience in NX/Teamcenter, including managing design releases from prototype to production Experience with Python, MATLAB, or similar tools for engineeri
