Senior Mechanical Engineer

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 The Anduril Rocket Motor Systems (RMS) team is on a mission to build next generation solid rocket motors for a safer, more connected world. To achieve our vision of becoming a large-volume provider of tactical rocket motors, we will develop differentiated products and services that maximize our customers’ capabilities, and we will establish and maintain a reputation of Quality and Reliability. ABOUT THE JOB Anduril's Production Engineering Team is seeking a highly skilled and driven Senior Mechanical Engineer to take holistic ownership of the design, development, and implementation of critical production tooling specifically for advanced solid rocket motors. Our Production Engineering Team is at the forefront of rapidly iterating and building cutting-edge defense hardware. We are the linchpin between innovative design and scalable manufacturing, ensuring our defense systems, particularly our solid fuel rocket motors, reach the warfighter at speed and scale. This role is crucial to accelerating that mission. WHAT YOU'LL DO Lead the end-to-end lifecycle of specialized manufacturing tooling for solid rocket motors, from initial concept and detailed design through prototyping, validation, full release, and successful implementation on the factory floor. Serve as the design authority for a diverse range of tooling, including jigs, fixtures, molds (for propellant casting, insulation, etc.), assembly aids, test fixtures, and specialized ground support equipment critical for SRM production. Drive the design process leveraging advanced CAD software, engineering analysis (FEA, DFM, DFA), and simulation to ensure tooling is robust, repeatable, ergonomic, and optimized for high-rate manufacturing. Take full ownership of the prototyping and validation phases, overseeing fabrication, assembly, testing, and iterating on designs to achieve optimal performance and manufacturability. Spearhead the transition from design to full production release, including creating comprehensive documentation packages, detailed work instructions, maintenance procedures, and quality control plans specifically for your owned tooling. Collaborate closely with internal manufacturing teams, quality engineers, and external vendors to define tooling requirements, manage fabrication, troubleshoot issues, and continuously improve tooling performance and lifespan. Apply rigorous Design for Manufacturability (DFM) and Design for Assembly (DFA) principles not only to the product but, critically, to the tooling itself, ensuring robust, efficient, and scalable production processes. Act as a primary technical resource for all matters related to the tooling you own, providing expert guidance and problem-solving support throughout the entire manufacturing value chain. REQUIRED QUALIFICATIONS Bachelor's degree in Mechanical Engineering or a closely related technical field. 8+ years of professional experience in mechanical engineering, with a significant focus on manufacturing or production engineering. Proven track record of holistic ownership over mechanical design projects from concept through full production release and implementation. Direct experience designing, prototyping, and implementing production-grade manufacturing tooling (e.g., jigs, fixtu
