• A Ph.D. in engineering or related field may be in lieu of three years of experience.
• Previous experience at X-energy exceeding performance standards may be in lieu of years of experience.
• Experience with mechanical process and/or commercial power generation equipment design, procurement, installation, and/or operation is required; for this role that experience must include designing and specifying pressure vessels and tanks based on system needs while considering all potential impacts of that selection throughout the life of the component, its associated system, and interfacing plant systems.
• Experience with authoring and/or maintaining company design standards and guides related to design, specification, and selection of tanks and pressure vessels is desirable.
• Systems or Design Engineering experience in successful mechanical system development projects.
• Experience with design and operation of mechanical systems including, but not limited to, steam, feedwater, condensate, HVAC, fire protection, drainage, compressed air, services, water-based systems, or nuclear systems.
• Knowledge of best practices for system requirements management and verification.
• Knowledge of Systems Engineering processes, as well as relevant aspects of nuclear power plant licensing, regulatory, quality, and safety requirements.
• Pressure vessel design principles: Expert knowledge of stress analysis, shell theory, nozzle reinforcement, flange design, and support structure design.
• Structural mechanics: Strong understanding of static and dynamic loads, fatigue analysis, thermal stresses, and mechanical property considerations.
• Codes and standards: Comprehensive knowledge of ASME Boiler and Pressure Vessel Code (especially SectionIII andVIII), API650/620, and other relevant codes and standards for nuclear and non‑nuclear applications.
• Materials engineering: Expertise in material selection based on process conditions, corrosion allowances, brittle fracture prevention, and material property degradation over time.
