Our team operates in a collaborative, entrepreneurial environment where employees are encouraged to solve challenging technical problems and advance the materials technologies needed for next‑generation energy systems.

NANO Nuclear Energyis seeking a Thermal Structural Engineer to support the design, analysis, and development of advanced microreactor systems. The successful candidate will contribute to thermal and structural evaluations of reactor components and supporting systems, including heat transfer analysis, mechanical design evaluations, finite element analysis (FEA), and engineering documentation. Mo reexperienced candidates are encouraged to apply and may take on expanded technical ownership, mentoring responsibilities, and leadership of analysis activities.

• Perform thermal and structural analyses supporting the design and development of advanced microreactor systems.
• Conduct heat transfer, thermal stress, and mechanical performance evaluations for reactor components and subsystems.
• Develop and execute engineering analyses using analytical methods and simulation tools such as ANSYS, COMSOL, Abaqus, or equivalent.
• Support finite element analysis (FEA), computational modeling, and design optimization activities.
• Evaluate components under steady‑state, transient, and accident‑condition operating scenarios.
• Support mechanical design activities including component sizing, material selection, and design verification.
• Prepare engineering calculations, technical reports, design documentation, and presentations.
• Collaborate with nuclear, mechanical, materials, systems, and licensing teams.
• Participate in design reviews, testing activities, and engineering problem‑solving efforts.
• Apply engineering principles and industry standards to support safe and reliable reactor designs.

• Bachelor’s degree in Mechanical Engineering, Nuclear Engineering, Aerospace Engineering, Chemical Engineering, or a related engineering discipline required;
  Master’s degree preferred, with flexibility on years of experience.
• 5+ years of engineering experience.
• Strong understanding of heat transfer, thermodynamics, fluid mechanics, and mechanics of materials.
• Experience with thermal‑fluid systems, structural analysis, pressure vessels, high‑temperature components, or similarly complex engineering systems.
• Strong computational analysis and engineering simulation experience.
• Experience with ANSYS, COMSOL, Abaqus, or similar advanced engineering analysis tools.
• Experience with MATLAB, Python, or other modeling and programming tools is valuable, particularly when used for engineering analysis and simulation. The relevance of this experience will be evaluated based on how these tools have been used in practice.
• Ability to communicate complex technical information clearly through written reports, presentations, and technical discussions.
• Ability to work collaboratively within a multidisciplinary engineering environment.
• Nuclear experience is highly preferred but not required. Relevant…
