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.

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).

Required Skills / Qualifications

• 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, Solid Works Simulation, or similar).
• Experience evaluating structural loads, mechanical components, and degradation.
• Strong technical writing and communication skills.
• Ability to support multiple concurrent engineering tasks.

Desired Skills / Qualifications

• Exposure to nuclear mechanical assessments, ASME Code rules, or reactor internals evaluations.
• Background in fatigue analysis, fracture mechanics input prep, or thermal-mechanical load assessment.
• Experience with CAD / 3D modeling (Solid Works, Inventor) and data analytics.
• Familiarity with aging management, inspection programs, or system modifications.

Pay Range

The expected salary range for this role is $101,040 - $184,560 in San Jose, CA; $86,160 - $156,120 in Denver, CO; and $79,900 - $145,320 in Charlotte, NC. Exact pay will be commensurate with experience.
