Required Skills: •Prometheus Energetics is seeking an experienced •Structural Design & Material Evaluation •Lead structural sizing, margin-of-safety assessments, and strength evaluations for solid rocket motor components, including composite filament-wound cases, metallic pressure vessels, nozzle structures, igniter housings, and interstage structures. •Evaluate orthotropic and anisotropic material behavior for composite structures (e.g., carbon fiber/epoxy wet-wound and prepreg layups) and high-strength metallic alloys (e.g., titanium, maraging steel, aluminum). •Characterize viscoelastic material behavior, structural margin, and cumulative damage models for solid propellant grains, liners, and insulation bond lines across storage, transportation, thermal cycling, and operational firing profiles. •Define structural interface requirements, fastener joint designs, skirts, polar cleats, and bond line shear limits to ensure structural integrity across proof testing, flight, and post-burn heat-soak environments. •Support scalable manufacturing processes (e.g., fiber placement, automated tape laying, hand layup, hydrotesting, and machining) to transition structural designs from prototype into high-rate production. •Develop and maintain complex 2D and 3D finite element models (FEM) using industry-standard tools (e.g., Abaqus, ANSYS, Nastran/Patran, HyperMesh, or custom solvers). Qualifications: •Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, Structural Engineering, or a closely related technical field from an accredited institution. •Master’s Degree or Ph.D. in Aerospace, Mechanical, or Structural Engineering with a focus on composite materials, non-linear FEA, or structural dynamics. •Active U.S. Government Secret Security Clearance. •Direct experience with Filament Wound Composite Pressure Vessels (COPV), composite skirt joint design, or nozzle structural analysis. •Applied scripting experience in Python, MATLAB, or APDL/Abaqus user subroutines (UMAT/VUMAT) for automated mesh generation, post-processing, or custom material law implementation. •Knowledge of aerospace pressure vessel standards (e.g., AIAA S-080/S-081, MIL-STD-1522A, NASA-STD-5001). •Work is performed in office, machine shop, laboratory, and energetics manufacturing environments, including high-hazard areas subject to enhanced safety and security controls. •Must be able to wear required personal protective equipment (PPE) and comply with site safety, explosive-safety, electrostatic discharge (ESD), and access-control requirements. •Demonstrated capacity to move throughout a manufacturing site, inspect physical tooling, participate in shop-floor audits, and occasionally lift up to 25 pounds. •Regular, reliable attendance is required. Periodic travel to vendor machine shops, secondary company facilities, or customer sites may be required during startup, tool qualification, or critical production events.
