Job description

Career Opportunities: Senior Civil Structural Designer (1704)

The Senior Civil Structural Designer will design metallic, concrete, and modular structures, systems, and components for the SMR-300 plant, supporting engineering and licensing requirements for deployment worldwide. The role requires a willingness to learn and develop practical solutions to challenging design problems, while closely coordinating with fabrication and construction partners to ensure constructability. The designer will also support Holtec’s deployment of a novel modular steel-concrete structural system that enables accelerated schedules and reduced costs through extensive shop fabrication and site automation.

Primary Responsibilities:

• Develop detailed 3D models and 2D design drawings for civil, structural, and architectural structures, systems, and components (SSCs) supporting the SMR-300 Small Modular Reactor program.
• Prepare general arrangement (GA) drawings, fabrication drawings, erection drawings, and structural connection details for steel, concrete, and composite structures.
• Utilize AutoCAD, Tekla, Revit, and other design software to create accurate engineering models and construction documentation.
• Support the design and deployment of modular steel-concrete structural systems that facilitate accelerated construction schedules, enhanced constructability, and cost-efficient project execution.
• Coordinate closely with civil, structural, mechanical, piping, and equipment engineers to integrate design requirements into plant layouts and structural arrangements.
• Develop structural detailing for foundations, concrete slabs, steel framing systems, platforms, gratings, supports, and other plant structures.
• Review equipment layouts, piping general arrangement drawings, and isometric drawings to ensure structural interfaces are accurately incorporated into design deliverables.
• Collaborate with fabrication shops, suppliers, and construction organizations to ensure designs are practical, manufacturable, and constructible.
• Assist in resolving design challenges through innovative engineering solutions while maintaining compliance with project requirements and applicable industry standards.
• Generate and maintain design documentation, drawing packages, model revisions, and associated technical records in accordance with quality assurance requirements.
• Support engineering analyses and design verification activities by providing accurate geometry, structural layouts, and design data.
• Incorporate applicable U.S. and international codes, standards, and industry best practices into structural detailing and design documentation.
• Participate in design reviews, interdisciplinary coordination meetings, constructability reviews, and model walkthroughs.
• Support nuclear licensing and regulatory documentation efforts by providing design information and drawing updates as required.
• Assist with field support activities, fabrication reviews, and construction issue resolution during project execution.
• Contribute to the continuous improvement of design processes, modeling standards, drafting practices, and modular construction methodologies.

Requirements:

• Diploma or Bachelor’s Degree in Civil or Structural or Mechanical Engineering
• 5 years of experience using AutoCAD or Tekla to create 3D models and 2D detailed drawings
• Formal training in AutoCAD, Tekla, Revit or SolidWorks
• Conversant in Revit for concrete structure detailing and Tekla for structural steel detailing
• Experience in producing GA drawings and connection details for SSCs
• Experience in working with engineers, fabricators, and constructors in developing drawings
• Knowledge of weld symbols and structural design codes and standards
• Capable of reading equipment layouts, piping GA and isometric drawings
• Display creative skills and problem-solving approach for resolving design issues
• Excellent technical writing and communication skills
• Prior experience in nuclear industry
• Industry experience in designing building foundations, elevated slabs and steel gratings
• Exposure to US and UK civil and structural codes and standards
• Experience in creating meshed models using HyperMesh or ANSYS
• Exposure to large scale fabrication and construction activities
• Experience in modular design development of SSCs
