team lead
  • Use engineering tools, including finite element analysis (FEA) simulation software, hand calculations, and engineering judgment, to assess stress, deformation, degradation behavior, and lifetime mechanical performance of these nuclear reactor components.
  • Provide feedback and guidance to more junior team members with the execution of the core tasks and responsibilities listed in the Job Profile Task/Responsibilities section of this document.
  • Lead small groups of engineers to solve complex technical problems and deliver high quality engineering work products on time and within budget.
  • Maintain professional demeanor and behavior at all times in all forms of communication.
  • Perform and assist structural analysis for systems, structures, and components of X-energy developed reactors, including pressure vessels and piping, reactor internals, nuclear fuel, and high temperature materials such as graphite.
  • 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.
  • Write and develop design documentation including design basis documents, technical reports, calculations, and drawings in accordance with applicable procedures.
  • Perform work in accordance with X-energy quality procedures for design and configuration management to ensure project quality requirements are met.
  • 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 to ensure SSCs can meet technical requirements.
  • Identify, collect, and document applicable requirements, interfaces, design basis and criteria by coordinating with key stakeholders/systems engineers and support identifying applicable industry codes and standards and the direction of project leads and systems engineers.
  • Develop Verification and Validation (V&V) plans for analytical tools and support qualification of toolset.
  • Planning and performing the analysis required to assess aspects of the SSCs to ensure they can perform their intended functions and meet technical specifications and design requirements.
  • Provide independent reviews and acceptance reviews of engineering deliverables and data.
  • Support the assessment of SSCs for manufacturability as well as assembly and integration considerations at the direction of project leads.
  • Lead the execution of the core tasks and responsibilities listed in the Job Profile Task/Responsibilities section of this document, without close supervision and some latitude for independent judgement.

Culture + Values

50% Growth
Global Energy Growth
Global energy demand is expected to rise by 50% over the next 30 years, driven by population growth and economic development.
  • We’re empowering Solar, wind and hydro are parts of the solution. Nuclear is the only pure base‑load, load‑following, highly scalable, locatable anywhere, stand‑alone or complementary solution. It's an integral piece of the puzzle.
  • Zero Emissions: We believe in leaving a cleaner planet for our children and grandchildren, while continuing to provide sufficient and affordable power to sustain growing populations around the world.
  • Clean Water: X‑energy’s core competencies in HTGR design and high‑temperature fuel design/manufacture makes a unique and compelling combination to apply our skills to Nuclear Thermal Propulsion.
  • Space & Nuclear: The world is facing a pair of challenges … global energy demand is expected to rise by 50 % over the next 30 years. At the same time, we must significantly lower carbon emissions.
  • Our technology relies on physics, not mechanical systems.
