About The Position

Structural Integrity Associates (SIA) is seeking a Senior Mechanical Engineer or Consultant to support mechanical analysis and assessment of nuclear components, reactor internals, pressure boundary systems, and mechanical hardware. This role focuses on structural analysis, FEA-based evaluations, degradation assessments, and mechanical support for aging management programs. It blends mechanical design, analysis, FEA, and problem-solving. Candidates should have strong mechanical analytical skills, experience evaluating loads and stresses on components, and an interest in complex mechanical systems within operating nuclear plants.

Requirements

• B.S. or M.S. in Mechanical Engineering or related discipline.
• 4–10 years of mechanical engineering experience (preferably power/nuclear or similar heavy industry).
• Experience with FEA (ANSYS, Abaqus, SolidWorks Simulation, or similar).
• Experience evaluating structural loads, mechanical components, and degradation.
• Strong technical writing and communication skills.
• Ability to support multiple concurrent engineering tasks.

Nice To Haves

• Background in fatigue analysis, fracture mechanics input prep, or thermal-mechanical load assessment.
• Experience with CAD/3D modeling (SolidWorks, Inventor) and data analytics.
• Familiarity with aging management, inspection programs, or system modifications.

Responsibilities

• Mechanical and Structural Analysis Perform mechanical and structural evaluations for reactor internals, vessel components, and pressure boundary hardware. Participate in evaluations of mechanical degradation including fatigue, cracking, wear, or thermal-mechanical aging. Review engineering drawings, specifications, and inspection data to support mechanical integrity decisions.
• Component and System Evaluation Support design or redesign of mechanical components, incorporating operational load conditions and aging effects. Participate in evaluations for equipment modifications, upgrades, or corrective actions. Support emergent outage work including root-cause evaluations, foreign material assessments, or mechanical damage investigations.
• Project Execution and Reporting Prepare technical reports, drawings packages, analyses, and calculation files with nuclear-grade quality. Collaborate with cross-functional teams (materials, chemistry, FEA, piping) to develop integrated solutions.
• Client Engagement & Business Development Contribute to proposals, scopes, estimates; identify growth opportunities
• Collaboration & R&D Collaborate across disciplines; contribute to internal R&D roadmap and industry activities (e.g., EPRI participation, method improvements).
