The role

You will design and develop concrete and precast structural systems for manufacturing and deployment sites. This includes performing structural analysis, conducting trade studies, and managing fabrication and testing for microreactor infrastructure.

What you will do

• Ownership of critical concrete structures such as spent fuel dry cask storage systems, factory and facility foundations, and precast concrete elements.
• Conduct trade studies and develop designs for static, thermal, and seismic loading conditions.
• Perform detailed structural analysis and dynamic analysis using hand calculations and finite element tools.
• Develop and execute construction, fabrication, and test plans for precast and cast-in-place concrete elements.
• Create and manage a Bill-of-Materials (BOM).
• Find and develop suppliers and fabricators for precast concrete components.
• Own subassembly/structure design, fabrication, and test schedules.
• Own risk analysis (FMEA) for concrete structural subsystems.
• Collect requirements and provide expertise to engineers in other functional areas.

Required qualifications

• Bachelor's degree from an accredited institution in Civil, Structural, or Mechanical Engineering.
• 5+ years of experience designing concrete or reinforced concrete structures.
• 4+ years of experience performing structural analysis using both hand calculations and finite element tools (Abaqus, Ansys, SAP2000, or similar).

Nice to have

• Active PE license
• Experience with reinforced concrete design codes (ACI 318 or similar)
• Experience designing precast concrete systems, including handling, transport, and erection considerations
• Experience with dry cask storage design or spent nuclear fuel storage systems
• Experience with seismic design/qualification of concrete structures
• Experience with nuclear or other critical-facility structural design
• Experience designing hardware/structures that were fabricated, deployed, and iteratively improved
• Experience resolving thermal expansion and thermal gradient issues in concrete designs
• Experience working with interdisciplinary teams (mechanical, civil, geotechnical)
• Solid understanding and application of GD&T and construction tolerancing
