Warhead Design Engineer - Modeling & Simulation

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 Lethality team is responsible for the design, analysis, testing, and transition to production of advanced warhead and ordnance systems across multiple platforms. This team operates at the intersection of design engineering, explosives understanding, safety, test execution, and numerical analysis to help Anduril build high-performing, mission-relevant systems faster and with better technical judgment. This is not a narrow, siloed engineering environment. The team supports a broad range of applications across land, air, sea, ship, underwater, and other mission contexts, depending on where warhead-related capability is needed. In practice, that means the team contributes not only to design maturity and performance analysis, but also to safety-related questions such as storage compatibility, accidental initiation, sympathetic detonation risk, and other system-level concerns. The team also plays a critical role in helping Anduril move quickly without relying on unnecessary physical testing. Numerical analysis and simulation are used to guide design decisions, shape experimental setups, inform diagnostic strategies, interpret results, and improve future product and proposal work. This role sits directly in that loop. ABOUT THE JOB Anduril is looking for a Warhead Design Engineer — Modeling & Simulation to join the team in Costa Mesa, CA. This role is for an engineer who can use academic literature, empirical data, first-principles reasoning, and computational modeling to help steer warhead design and related ordnance decisions from concept maturity through testing and toward production readiness. The objective of this role is not simply to run simulations. It is to use modeling and analysis as an engineering tool to improve decisions across design, explosive selection, initiation concepts, test planning, and post-test interpretation. The right person will help the team evaluate performance at a high level, build credible pre-test predictions, correlate model outputs to test data, and contribute to the broader engineering understanding needed to support complex munitions systems. This role will support work across multiple programs rather than sitting in a tightly bounded lane. It is a strong fit for someone who wants broad technical exposure, meaningful influence on real engineering decisions, and the opportunity to work alongside a deeply technical team on some of the hardest warhead and effects problems in the business. Steven Todd described the role as one that should not be overly pigeonholed and that may grow into broader ownership over time depending on the person’s strengths. WHAT YOU’LL DO Leverage academic studies and literature, empirical data, and simulation to steer the design of warheads and missile/ordnance systems from concept design maturity to production. Analyze lethality and performance using hand-calculations (Gurney equations) and multi-physics modeling and simulation tools (CTH, Sierra, Zapotec, etc.) Create pre-test predictions and correlate models with test data. Manage arena and system testing of munitions products from end-to-end, including project planning, design of experiments, and safety. Capture test video, compile data from ground and flight tests, and analyze results. Ass
