Senior Civil​/Structural Engineer

Overview

Senior Civil/Structural & Seismic Engineer role ks closely with product teams—particularly those designing reactor enclosures, foundations, and site facilities. Ensures microreactors meet natural phenomena hazards design criteria (e.g., seismic, wind, flood), site/facility engineering requirements, and regulatory expectations. Translates civil/structural design solutions into engineering documentation and coordinates with regulatory bodies. Collaborates with product engineering to shape robust and compliant reactor infrastructure from concept through final design reviews.

• Evaluate and advise on structural loads, seismic design categories, and foundation layouts for transportable microreactors.
• Review and refine civil/structural drawings at conceptual, preliminary, and final design stages in accordance with regulatory specifications.
• Provide real-time feedback on load paths, anchorage, and site-specific solutions (e.g., desert vs. maritime environment).
• Own relevant inputs to the Documented Safety Analysis (DSA) for civil/architectural, structural integrity, earthquake/flood/wind hazard analysis.
• Respond to regulator inquiries (NRC, DOE) about civil/structural codes, site conditions, and anchorage methods.
• Prepare design deliverables demonstrating compliance with site hazards analyses and structural safety margins.
• Ensure that each stage of design review (30%, 60%, 90%) properly documents structural load cases, geotechnical data, and seismic analysis.
• Maintain consistent code interpretations across the organization.

• Bachelor’s degree in Civil or Structural Engineering (or a related Engineering or Physics discipline).
• 5+ years of experience in structural design or analysis for complex projects (e.g., energy, aerospace, or industrial).
• Familiarity with seismic design standards (e.g., ASCE/SEI 7, DOE-STD-1020) and civil/structural codes.
• Hands-on experience preparing or reviewing design drawings, calculations, and site plans.

• Master’s degree in Civil or Structural Engineering or related field.
• Prior experience in nuclear or highly regulated environments, with knowledge of seismic qualification for facilities.
• Experience liaising with government or regulatory bodies for site permitting or hazard classification.
• Proficiency in advanced structural analysis software (e.g., ANSYS, SAP
  2000) and geotechnical evaluation.
• Excellent communication skills to convey design rationale and regulatory compliance in cross-functional teams.

• Ability to work long hours and weekends as necessary to support critical milestones.
