Senior Nuclear Systems Engineer

Senior Nuclear Systems Engineer

The Senior Nuclear Systems Engineer supports the development of a next-generation nuclear power plant as part of a multidisciplinary engineering team responsible for Nuclear Island (NI) systems-level design. This role is intended for experienced engineers who can act as a technical authority for assigned NI systems, independently leading system-level design, integration, and licensing activities while mentoring junior engineers in a highly regulated environment.

Supporting the SMR-300, this position works closely with engineering, manufacturing, and licensing teams as part of a U.S. Government cost-shared development program, developing system requirements, specifications, analyses, and design documentation to support safe, compliant, and executable plant designs.

Location:

Camden, NJ or North Pittsburgh, PA (Relocation assistance available!)

• Lead multi-disciplinary system engineering and integration activities across major SMR-300 plant systems, ensuring technical consistency and alignment across engineering disciplines
• Develop and manage system requirements, interface definitions, and component specifications to support detailed design, analysis, and licensing activities
• Serve as a technical mentor to early-career and mid-level systems engineers, providing design guidance and reviewing calculations, specifications, and technical deliverables
• Perform and oversee engineering analyses and calculations, particularly in areas related to thermal-fluids and overall plant system performance
• Conduct and support technical trade studies and design evaluations that inform high-impact decisions affecting plant architecture, safety, and performance
• Coordinate closely with licensing, safety, and regulatory teams to ensure system designs support safety case development and meet applicable codes and regulatory expectations
• Collaborate with internal engineering teams, suppliers, and manufacturing partners to ensure system designs are technically sound, manufacturable, and executable
• Support technical reviews, design documentation development, and internal design approval processes in alignment with program milestones and quality standards
• Serve as a technical lead for assigned Nuclear Island systems, owning system integration, requirements, and cross-discipline alignment
• Execute assigned system-level engineering scope for the SMR-300 development program, delivering work with a high standard of quality, safety, and regulatory rigor

• Bachelor's degree in Engineering (Mechanical, Nuclear, Electrical, or related discipline);
  Master's degree preferred
• 8+ years of progressive engineering experience, with demonstrated growth in technical responsibility and scope
• Prior experience serving as a system owner or lead engineer for safety-related Nuclear Island (NI) systems on an operating or new-build nuclear power plant strongly preferred
• Demonstrated experience mentoring and technically developing junior engineers, including review of designs, calculations, and system-level deliverables
• Proven ability to lead multidisciplinary engineering teams, resolve highly complex technical issues, and drive system-level decisions
• Strong fundamentals in heat transfer and fluid dynamics, with demonstrated application to complex plant systems
• Experience developing engineering designs, specifications, drawings, and technical requirements in collaboration with engineers, suppliers, and manufacturers
• Experience working in the nuclear energy industry in a system design or systems engineering capacity preferred; candidates with aerospace, defense, or other regulated-industry systems experience also encouraged
• Familiarity with engineering and design tools such as Smart Plant, Mathcad, AutoCAD, Pipe Flo, HTRI, Engineering Lifecycle Management (ELM), and requirements management tools (e.g., DOORS NG) preferred
• Excellent technical writing, communication, and stakeholder engagement skills
• Proficiency in Microsoft Office applications, particularly Word and Excel
• EIT and/or PE certification preferred
