  • Communicate complex technical issues and provide direction on key design trades, technical decisions, requirements allocation, system interfaces, and design margins affecting reactor system performance and safety.
  • Lead or support major design integration reviews to ensure structures, systems, and components are compatible, accessible for installation and maintenance, and aligned with safety, construction, and lifecycle requirements.
  • Prepare and review reactor systems design documentation and supporting engineering analyses, including design descriptions, drawings, test plans, reports, specifications, calculations, design decision records, thermal/structural/system analyses, FMEAs, hazard analyses, and design margin assessments.
  • Maintain knowledge of and assess compliance with applicable codes and standards such as ASME, ANSI, ASTM, ASME Boiler and Pressure Vessel Code, and other relevant industry standards.
  • Assist in cost, schedule, and risk assessments related to reactor system design, testing, fabrication, integration, and deployment activities.
  • Mentor engineers across Reactor Systems and adjacent technical teams, including coaching on design rigor, engineering judgment, documentation quality, and cross-functional integration.
  • Represent Reactor Systems in high-impact technical discussions, design reviews, readiness reviews, audits, and executive-level technical briefings.
  • Promote a strong engineering culture focused on safety, technical excellence, accountability, clarity, and efficient execution.
  • Other duties as assigned.

What they require

  • Bachelor’s or advanced degree in Mechanical Engineering, Nuclear Engineering, or a related technical discipline is required.
  • 20+ years of progressively increasing technical leadership experience in nuclear reactor design, reactor systems engineering, advanced technology development, complex mechanical systems, high-temperature systems, or similarly regulated engineering environments is required.
  • Demonstrated experience leading major technical scope across complex engineering programs, preferably involving nuclear, energy, chemical, oil and gas, or power generation systems is required.
  • Recognized technical authority with demonstrated contributions to the advancement of advanced reactor technology, complex engineered systems, or related engineering disciplines through technical leadership, publications, patents, standards development, invited presentations, or equivalent achievements preferred.
  • Experience working within formal configuration management, design control, or product lifecycle management systems under a recognized quality program such as ASME NQA-1, ISO 9001, or equivalent is desired.
  • Experience with applicable codes and standards such as ASME Boiler and Pressure Vessel Code Section VIII Division 1 and 2, Section III Division 5, ANSI, ASTM, ASME Y14.5, or related standards is desired.
  • Experience participating in or leading formal technical reviews, readiness reviews, design reviews, or safety-related engineering reviews.
  • Experience communicating complex technical issues to executive, regulatory, quality, manufacturing, operations, or cross-functional stakeholders.
  • Recognized expert capable of defining technical vision and engineering strategy across multiple engineering disciplines.
  • Strong understanding of advanced reactor technology, high-temperature systems, molten salt systems, reactor vessel systems, reactor internals, auxiliary systems, and safety-significant mechanical components.
  • Knowledge of high-temperature design considerations, including thermal stress, creep-fatigue, irradiation effects, material compatibility, and component degradation mechanisms.
  • Ability to establish long-term technical vision and guide engineering organizations toward successful execution of complex technology roadmaps.
  • Ability to influence technical direction without organizational authority and align long-term technology strategy with business objectives.
  • Ability to interpret and apply industry codes and standards, including ASME, ANSI, ASTM, and ASME BPVC.
  • Ability to evaluate enterprise-level technical tradeoffs involving safety, manufacturing, operability, licensing, economics, and commercialization.
  • Familiarity with 3D CAD design tools such as SolidWorks, AVEVA, or equivalent, and engineering analysis tools for thermal and structural modeling.
  • Knowledge of FEA, CFD, thermal-fluid analysis, structural analysis, and system-level analysis methods, with the ability to apply analysis results to design decisions.
  • Ability to evaluate design maturity, technical readiness, test adequacy, and verification strategy for first-of-a-kind reactor systems.
  • Strong analytical problem-solving abilities to resolve complex design issues efficiently.
  • Ability to make sound engineering recommendations with incomplete information while identifying risks, assumptions, and required follow-up actions.
  • Excellent technical writing skills and ability to produce clear, concise, reviewable engineering documentation.
  • Provide independent engineering judgement on the organization’s highest-risk technical decisions.
  • Flexibility to consistently deliver tangible results in a rapid and dynamic work environment.
  • Capable of mentoring Principal Engineers, Lead Engineer, Senior Engineers, and emerging technical leaders while strengthening organizational engineering capability and succession planning.
