X-energy is seeking a Thermal Analysis Engineer responsible for the engineering design and development of mechanical systems, structures, and components. This includes concept development, evaluation of concepts, analysis of systems, structures, and components for their ability to perform their intended function, and ensuring they meet all technical specifications and requirements. The role will ensure the development of the systems and components through production including any necessary prototyping, testing, and commissioning.

• Develop mechanical/physical concepts, design and support development of processes to create or identify structures, systems, and components (SSCs) for use in nuclear products or facilities with a focus on nuclear safety.
• Identify, collect, and document applicable requirements, interfaces, design basis and criteria by coordinating with key stakeholders/systems engineers and supporting the identification of applicable industry codes and standards.
• Plan and perform the analysis required to assess aspects of the SSCs to ensure they can perform their intended functions and meet technical specifications and design requirements.
• Perform computations utilizing hand calculations and analytical tools for structural, thermal, hydraulic, and other scoping calculations as required at the direction of project leads and systems engineers.
• The role may include specialization in one or more of the following areas:
  • Thermosystems
    • Perform system-level thermodynamic analyses and process design using system-level simulation codes to support design iterations of X-energy developed reactors and supporting subsystems.
    • Support the sizing and analysis of components including heat exchangers, pumps, circulators, and turbo machinery.
    • Support the development of reactor and plant control philosophy and implement in plant models, simulations, and digital twins.
• Support the assessment of SSCs for manufacturability as well as assembly and integration considerations at the direction of project leads.
• Write and develop design documentation including design basis documents, technical reports, calculations, and drawings in accordance with applicable procedures.
• Develop Verification and Validation (V&V) plans for analytical tools and support qualification of toolset.
• Perform work in accordance with X-energy quality procedures for design and configuration management to ensure project quality requirements are met.
• Provide independent reviews and acceptance reviews of engineering deliverables and data.
• Maintain professional demeanor and behavior at all times in all forms of communication.
• Perform other duties as assigned by manager.

• Bachelor’s degree in mechanical engineering, or related engineering discipline (e.g., nuclear aerospace, chemical, etc.) from an accredited institution required.
• Typically, five years of experience in an engineering role required.
• A master’s degree in engineering or related field (may include a combination of experience obtained through an academic institution) may be in lieu of two years of experience.
• 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.
• Proficiency with engineering hand calculations is required.
• Experience and/or knowledge in a minimum of one of the following areas:
  • Thermodynamics
    • Use of 1D flow-solvers performing heat/energy and mass balance (e.g., RELAP, Flownex, NPSS, SINDA/FLUINT, Flomaster, or similar).
