Stress Analysis 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 Maritime Manufacturing Technology team is responsible for rapidly developing and implementing manufacturing technologies and processes for cutting-edge defense hardware, including deployable static and moving surface, undersea and sea to air vehicles and scaling these products in our new manufacturing facilities.

ABOUT THE JOB

We are looking for a Stress Analysis Engineer to join our rapidly growing team in Santa Ana, CA to lead stress analysis, materials characterization, and design allowables development for mission-critical maritime and subsea hardware. In this role, you will be the foundational structural authority bridging the gap between classical stress analysis, finite element modeling (FEM), and Materials & Processes (M&P) metallurgy.

You will own the structural integrity of advanced pressure-boundary enclosures, launch systems, and high-consequence maritime structures from clean-sheet architecture through fabrication and qualification testing. This is an individual contributor role with high autonomy and the opportunity to scale into a technical capability lead as the product line expands.

WHAT YOU’LL DO

• Structural Analysis & Sizing: Perform classical hand calculations (first-principles, Roark, Bruhn) and advanced Finite Element Analysis (FEA) including linear, non-linear, buckling, fatigue, and fracture mechanics on complex maritime pressure boundaries, structural enclosures, and mechanism assemblies.
• Material Allowables & Characterization: Define, build, and maintain statistical structural design allowables (A- and B-basis) across primary metallic and composite materials. Define coupon-level test matrices to characterize tensile strength, fatigue, fracture toughness, and environmental degradation.
• Allowables Database Ownership: Serve as the custodian of the centralized allowables database across engineering teams, establishing clear thresholds for requalification when processing, vendor sources, or material lots change.
