About the role

Stress Analysis Engineer to lead stress analysis, materials characterization, and design allowables for mission-critical maritime and subsea hardware. Bridges classical stress analysis, FEM, and Materials & Processes metallurgy, owning structural integrity from concept through fabrication and qualification.

Responsibilities

  • Structural Analysis & Sizing: Perform classical hand calculations (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 effects—including residual stresses, weld shrinkage/distortion, and surface finishes—in 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 with internal test teams and external facilities to scope, schedule, and execute test plans.

Qualifications

  • Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, Structural Engineering, Materials Science, or related 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 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) and working 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.
  • Ability to manage competing priorities, interface with cross-functional design and manufacturing teams, and wear multiple technical hats to drive hardware to completion.
  • Eligible to obtain and maintain an active U.S. Secret security clearance.
