• Typically 4–6 years of post-graduation engineering experience; advanced engineering degree may be considered toward relevant experience.
• In‑depth knowledge of heat transfer and fluid dynamics fundamentals.
• Demonstrated ability to independently execute moderately complex system design, analysis, or integration assignments with minimal technical guidance.
• Experience developing engineering calculations, system design documentation, technical specifications, and design bases.
• Demonstrated experience developing, managing, and verifying engineering requirements.
• Experience coordinating engineering interfaces across multiple technical disciplines.
• Excellent technical writing, interpersonal, and effective communication skills.
• Experience working in the nuclear energy field.
• Experience with listed software tools and certifications (Smart Plant, MathCad, AutoCAD, Pipe-Flo, ELM, DOORS‑NG, HTRI).

Responsibilities

• Independently perform the design, development, and integration of assigned plant systems for the SMR-300 small modular reactor program.
• Perform and review engineering evaluations, calculations, and analyses related to thermal-hydraulic, mechanical, and process system design.
• Develop and maintain system design documentation, including system descriptions, design specifications, engineering calculations, technical reports, and design bases.
• Develop, verify, and manage system requirements and resolve requirements-related issues within assigned technical scope.
• Coordinate with component, mechanical, civil, electrical, I&C, and licensing engineers to manage system interfaces and resolve cross-disciplinary design issues.
• Lead the selection, specification, and technical evaluation of plant equipment and components within assigned systems.
• Prepare and review engineering drawings, models, vendor documentation, and other design deliverables for technical adequacy and consistency with system requirements.
• Independently identify, evaluate, and resolve moderately complex technical issues through engineering analysis and coordination with internal and external stakeholders.
• Lead or provide significant technical contributions to design reviews, technical meetings, and cross-functional project activities.
• Ensure engineering deliverables comply with applicable codes, standards, quality requirements, design bases, and regulatory expectations.
• Support licensing activities by developing technical information, resolving technical questions, and supporting responses to internal and regulatory requests.
• Maintain engineering documentation and configuration control throughout the design lifecycle and ensure changes are appropriately evaluated for system and interface impacts.
• Provide technical guidance and mentoring to less-experienced engineers and support review of their engineering work products.
• Coordinate assigned engineering scope with project schedules and communicate technical risks, issues, and potential impacts to project leadership.
