Job summary

TerraPower is seeking a Technical Lead in Mechanical Engineering Analysis to drive the mechanical performance evaluation of reactor core components and structures. You will lead a team of analysts and collaborate with engineers and scientists to advance next-generation nuclear designs.

The role focuses on mechanical analysis, stress, seismic, buckling and thermal assessments using ABAQUS/ANSYS, with a strong emphasis on ASME code compliance and high-quality documentation.

Qualifications

• B.S., M.S. or Ph.D. in Mechanical Engineering from an accredited university.
• Minimum 10 years of mechanical analysis experience with a B.S. degree, or 8+ years with an M.S. or Ph.D. with a demonstrated ability to produce high-quality work.
• Minimum of 2 years of experience coordinating technical project teams with a demonstrated ability to meet project goals.
• Experience interfacing with other engineering disciplines.
• Proficient in finite element stress analysis, mechanical analysis methods and modeling tools with emphasis on ABAQUS or ANSYS.
• Strong understanding of solid mechanics, fracture mechanics, and metal fatigue principles.
• Experience in mechanical analysis of equipment or components (seismic, buckling, thermal, creep/inelastic).
• Experience in analysis to ASME Boiler/Pressure Vessel Code Section III and other ASME codes (VIII, B31.1, B31.3).
• High degree of trust, open communication, and teamwork.

Responsibilities

• Lead mechanical analyses of reactor structures, systems, and nuclear island components.
• Perform stress, creep-fatigue, buckling, seismic, and vibration analyses using classical tools and FEA software.
• Collaborate with cross-functional teams for static and dynamic analyses (linear and non-linear).
• Establish, review, approve and maintain documents of analysis results and design solutions.
• Direct inputs and methodologies to establish structural sizing and load combinations for critical components.
• Provide technical insights, mentorship and support high-quality work packages.
• Identify, define and coordinate activities for design, analysis, and verification of reactor structures.
• Participate in technical discussions on strategy, budget, goals, resources and team performance.
