We are seeking a highly technical Mechanical Design Engineer to support the X-300 SMR project, focused on the design and fabrication of nuclear mechanical components. You will be a key technical authority from design through fabrication and final acceptance, ensuring all components are "fit for service" and fully compliant with nuclear codes and standards. This role is critical to keeping the construction schedule on track and ensuring long-term plant reliability.

Key Responsibilities

• Design Ownership
• Develop and review mechanical component design specifications, calculations, and drawings.
• Define materials, weld details, and inspection requirements in accordance with ASME Section III.
• Approve CMTRs, CoCs, weld and NDE records, dimensional inspection reports, and final data packages.
• Fabrication & Vendor Oversight
• Support Vendor Response (VR) type issues such as, but not limited to, Supplier Change Requests, Inspection and Test Plans, Procedure Reviews, Vendor Document Reviews, etc.
• Translate design requirements into clear, buildable fabrication documents.
• Review and approve vendor fabrication procedures, manufacturing plans, and test plans.
• Monitor and resolve technical issues during fabrication, fit-up, and final inspection.
• Code, Qualification & Compliance
• Ensure compliance with ASME Section III (and related codes), and nuclear QA requirements (10 CFR 50 Appendix B / NQA-1).
• Support environmental and seismic qualification of components, and document justification for design/fabrication decisions.
• Lead resolution of non-conformances (NCRs) and design/fabrication open items.
• Cross-Functional Collaboration
• Work closely with design, analysis, quality, supply chain, and construction teams.
• Communicate technical risks, status, and trade-offs to leadership and suppliers.
