RESPONSIBILITES
Lead stress analysis of propulsion and fluid system hardware, including thrust chambers, feedlines, manifolds, valves, and pressurized components
Perform and review static, thermal, dynamic, and durability (fatigue, fracture, and damage tolerance) analyses to guide design decisions and ensure strength, stability, stiffness, and life requirements are met
Perform structural analysis using both finite element analysis (Ansys and/or Nastran) and classical hand calculations, and validate models against test data
Define and improve analysis methods, standards, best practices, and material allowables for propulsion and fluid systems
Generate interface loads and boundary conditions that drive sizing of downstream hardware
Develop test requirements for qualification campaigns, correlate analysis models with test data, and support anomaly investigations and design improvements
Collaborate with design, materials, manufacturing, and test engineers throughout the design lifecycle to drive manufacturable solutions
Produce clear, well-documented analysis reports, provide technical guidance and mentorship to less-experienced engineers, and review internal and external analyses
QUALIFICATIONS
Required
B.S. in Aerospace, Mechanical, or a related engineering discipline
5+ years of relevant experience in structural/stress analysis and qualification of aerospace or comparable high-performance hardware
Proficiency with finite element analysis (Ansys and/or Nastran) and classical hand analysis, with strong model validation and verification skills
Experience with fatigue, fracture mechanics, and damage tolerance methods for flight-critical hardware
Experience with thermal / thermo-mechanical stress analysis
Experience analyzing pressurized components such as lines, ducts, and bellows
Strong understanding of structural mechanics, load paths, and first principles related to structures and materials
Preferred
M.S. or PhD in Aerospace, Mechanical, or a related engineering field
Experience with analysis of liquid propulsion components, fluid systems, or rocket engine hardware
Experience with analysis of turbomachinery hardware
Experience with crack-growth / fracture software such as NASGRO or AFGROW
Experience with additive manufacturing structural analysis and material characterization
Experience correlating structural predictions with test or flight data
