About the role

We are seeking a skilled Mechanical Engineer with experience in pipe stress analysis to support the design and qualification of high-integrity piping systems for our advanced reactor projects. The ideal candidate will be proficient in ASME B31 piping codes and have experience or a strong interest in ASME Section III Class 1/2/3/A/B piping design.

What you'll do

• Perform pipe stress analysis using industry-standard software (e.g., CAESAR II, AutoPIPE) in compliance with ASME B31.1, or B31.3.
• Support the design, analysis, and documentation of nuclear piping systems under ASME Section III Class 1, 2, 3, A, or B requirements.
• Conduct pipe support evaluations, thermal expansion assessments, and seismic/operating load analyses.
• Interface with cross-functional teams including structural, thermal, and system design engineers.
• Prepare calculation packages, analysis reports, and design documentation for regulatory and quality reviews.
• Assist in the development and implementation of piping design standards and design review processes.

Qualifications

Required
