• Verify component performance against applicable engineering codes and standards including ASME, ASCE, and AISC requirements
• Support interdisciplinary engineering teams to optimize component and structural designs
• Develop and maintain engineering analysis documentation and technical reports
• Perform peer reviews and support engineering quality assurance processes
• Serve as a technical point of contact for assigned engineering tasks and analysis activities
• Mentor junior engineers and support development of technical team capabilities
• Assist engineering leadership with technical evaluations and project execution support

Qualifications

• B.S., M.S., or Ph.D. in Mechanical Engineering or related engineering discipline
• 8+ years of related experience with B.S., 5+ years with M.S., or 3+ years with Ph.D.
• Strong proficiency with finite element analysis (FEA) and mechanical analysis methods
• Advanced experience using ANSYS and SolidWorks
• Strong understanding of:
  • Structural mechanics
  • Fracture mechanics
  • Fatigue analysis
  • Thermal and buckling analysis
  • Creep-fatigue/inelastic analysis
