• Analyze equipment in accordance with applicable engineering codes and standards including ASME BPVC, ASCE, and AISC.
• Support structural evaluations including stress, fatigue, fracture mechanics, buckling, creep, and thermal analyses.
• Collaborate with mechanical, systems, and design engineers to optimize component designs for safety, manufacturability, and performance.
• Prepare engineering calculations, technical reports, and design documentation.
• Perform peer reviews to ensure compliance with engineering quality standards.
• Support design reviews and provide technical recommendations throughout the project lifecycle.
• Mentor junior engineers and provide technical leadership as needed.
• Serve as a technical resource for structural analysis activities.

Required Qualifications

• Bachelor's degree in Mechanical Engineering, Civil Engineering, Nuclear Engineering, Aerospace Engineering, or a related discipline.

• Experience working with pressure vessel and piping codes including:
  • ASME Section III
  • ASME Section VIII Division 2
  • ASME B31.1 and/or B31.3
• Experience performing engineering calculations and documenting analytical results.
• Excellent communication and teamwork skills.

Preferred Qualifications

• Nuclear industry experience.
• Seismic analysis experience using response spectrum and time-history methods.
• Knowledge of:
  • ASCE 4
  • ASCE 43
  • AISC N690
  • AISC 360
  • AWS D1.1
  • AWS D1.6
