Stress Analysis Engineer, Maritime Structures

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.

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 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.

• 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.
• M&P and Metallurgy Integration: Act as the primary analysis interface to Materials & Processes (M&P) and Manufacturing Engineering. Translate material specifications heat treatments and weld joint efficiencies (WPS/PQR) into actionable finite element models and structural margin calculations.
• Manufacturing Impact & Dispositions: Account for manufacturing-induced effectsincluding residual stresses weld shrinkage/distortion and surface finishesin structural assessments. Provide rapid quantitative stress dispositions for non-conformances deviations and material anomalies.
• Test Campaign Execution: Drive structural test programs from coupon-level mechanical testing to full-scale subcomponent qualification. Partner directly with internal test teams and external mechanical testing facilities to scope schedule and execute test plans.

• Bachelors or Masters 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.

• Prior experience with maritime subsea or pressure-vessel structural design (NAVSEA criteria ASME Section VIII ABS rules or deep submergence standards).
• Working knowledge of fatigue and fracture mechanics software (e.g. NASGRO) and damage-tolerance methodologies.
• Hands-on experience coordinating with external mechanical and environmental testing laboratories.
• Familiarity with modern CAD platforms (NX Creo SolidWorks) and automated scripting for analysis post-processing (Python MATLAB).
• Active U.S. DoD Secret or Top Secret clearance.
