About the Job

Requirements

  • A bachelor's degree in engineering, such as nuclear, chemical, or mechanical engineering, from an ABET-accredited university is required.
  • Typically, ten years of experience in an engineering role is required for level IV.
  • A master's degree in engineering or a related field may substitute for two years of experience; qualifying academic experience may include design projects, research, or design teams, in addition to professional experience.
  • A Ph.D. in engineering or a related field may substitute for three years of experience; qualifying academic experience may include design projects, research, or design teams, in addition to professional experience.
  • Previous experience at X-energy meeting performance standards may substitute for years of experience.
  • Ability to perform elementary mathematical model programming for engineering calculations.
  • Ability to interpret, apply, and assess standards.
  • Ability to perform engineering studies and manage project schedules and interfaces with minimal oversight.
  • Work in the office four to five days per week and travel 10% of the time.

Responsibilities

  • Perform safety analyses, including leading system-level thermal-fluid analyses and process design using one-dimensional system simulation codes.
  • Guide and initiate source-term analyses and radiological consequence analyses.
  • Lead development of models supporting licensing-basis event analysis and evaluations.
  • Develop verification and validation plans, including code verification and validation efforts.
  • Lead execution of the role's core tasks independently and without close supervision.
  • Provide feedback and guidance to more junior team members.
  • In collaboration with engineering leadership, set enterprise-level technical direction by developing and owning technology- or discipline-specific roadmaps, best practices, and design criteria.
  • Collaborate with engineering, project leadership, and the safety analysis team to provide project updates, maintain priorities, adapt to change, and raise project or timeline concerns.
  • Provide engineering and technical expertise and guidance to identify, analyze, and resolve problems of increasing scope and complexity.
  • Contribute to team decisions and business objectives through planning, organizing, estimating, scheduling, and monitoring work; respond to changing priorities and situations and make decisions that may affect the team's work.
  • Prepare technical reports, correspondence, documentation, calculations, and sketches for well-defined problems and analyses of increasing scope and complexity.
  • Conduct engineering and related studies and complete routine engineering projects with minimal oversight.
  • Develop, maintain, and produce safety-basis documents and program procedures.
  • Identify and describe how safety-basis requirements relate to existing and new designs and operations.
  • Develop, maintain, and produce technical documentation informing system and subsystem requirements and specifications.
  • Interface with customers and regulators during nuclear safety reviews and technical working-group meetings to comply with requirements and meet project objectives.
  • Perform other duties as assigned by the manager.

About the Company

X-energy

Develops SMR reactors and TRISO fuel

X-energy designs and develops Generation IV high-temperature gas-cooled pebble-bed reactors and the TRISO-X fuel for small modular reactors (SMRs). Its modular reactor units use TRISO fuel to operate at high temperatures, producing heat that powers electricity generation or process heat through conventional power cycles, with safety features built into the fuel and design. The company differentiates itself by combining a fully modular Gen IV gas-coooled platform with proprietary TRISO-X fuel and a clear path toward commercialization backed by substantial financing. Its goal is to deliver cleaner, safer nuclear energy at commercial scale by completing design, obtaining regulatory clearance, and deploying its SMR technology and fuel.
