Maritime Stress Engineer - FEA, Materials & Allowables

Anduril Industries, Inc.; Santa Ana, Northern (CA, KY); Hybrid; USD 129,000 - 171,000; Full time

Job summary

Anduril Industries, Inc. in Santa Ana, CA, is seeking a Stress Analysis Engineer to lead structural analysis, materials characterization, and design allowables for mission-critical maritime hardware, bridging classical methods with FEM and metallurgy.

You will own the structural integrity of pressure-boundary enclosures and launch systems from concept through fabrication and testing, with high autonomy and potential to scale as the product line grows.

Qualifications

• Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, Structural Engineering, Materials Science, or a related technical discipline.
• 4+ years (Mid) or 7+ years (Senior) of demonstrated experience in structural stress analysis on high-consequence hardware (aerospace, defense, marine/subsea, or space systems).
• Deep proficiency in both classical hand calculations and commercial FEA tools (e.g., Abaqus, ANSYS, Nastran/Patran, or HyperMesh).
• Practical experience developing design allowables using statistical methods (e.g., MMPDS methodologies) and working closely with metallurgy/materials teams on alloy selection, heat treatments, and welded joint efficiencies.
• Strong understanding of heavy metallic fabrication processes (machining, forging, casting, welding) and their influence on fatigue life and structural margins.
• Demonstrated ability to manage competing priorities, interface with cross-functional design and manufacturing teams, and wear multiple technical hats to drive hardware across the finish line.
• Must be a U.S. Person due to required access to U.S. export controlled information or facilities.
• Eligible to obtain and maintain an active U.S. Secret security clearance.

Responsibilities

• Perform classical hand calculations 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.
• Define, build, and maintain statistical structural design allowables (A- and B-basis) across primary metallic and composite materials.
• Serve as custodian of the centralized allowables database across engineering teams, establishing thresholds for requalification when processing, vendor sources, or material lots change.
• Translate material specifications, heat treatments, and weld joint efficiencies into actionable finite element models and structural margin calculations.
• Account for manufacturing-induced effects—including residual stresses, weld shrinkage/distortion, and surface finishes—in structural assessments.
• Drive structural test programs from coupon-level mechanical testing to full-scale subcomponent qualification with internal and external testing partners.
