About the RoleAs a Thermo-Mechanical Design Engineer, you will play a key role in developing, designing, qualifying, and deploying advanced heat exchanger systems for cutting-edge energy applications. You will work closely with Responsible Engineers and cross-functional teams to mature designs from concept through production. The ideal candidate will bring strong mechanical design fundamentals, thermal engineering knowledge, and hands-on hardware development experience to deliver reliable, high-performance heat exchangers and associated piping systems for next-generation energy applications.
Roles & Responsibilities- Perform mechanical design, modeling, and analysis of heat exchanger systems, ensuring thermal performance, structural integrity, and compatibility with system interfaces.
- Design and analyze heat exchanger inlet/outlet piping, manifolds, and associated mechanical interfaces, ensuring compatibility with system performance and installation requirements.
- Evaluate thermal stresses, differential thermal expansion, pressure loads, piping flexibility, and mechanical loads transmitted between heat exchangers, piping, and supporting structures.
- Support development of manufacturing methods, including material selection, fabrication processes, joining techniques, and assembly of heat exchanger and piping components.
- Design and support development of test articles, test stands, and procedures to validate thermal performance, structural integrity, and operational life.
- Coordinate with internal teams and external stakeholders to translate system requirements into manufacturable and reliable hardware products.
- Support the design and integration of piping connections, flanges, weld joints, supports, and other fluid-system components, considering manufacturability, assembly, inspection, and maintenance.
- Define operating limits and performance envelopes for heat exchanger systems.
- Investigate hardware failures, identify root causes, and rapidly implement design improvements to enhance performance and reliability.
Basic Qualifications- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Nuclear Engineering, or a related physics-based field.
- 5+ years of experience in mechanical or thermal engineering, preferably involving heat exchangers, pressure-containing equipment, or high-temperature systems.
- Demonstrated experience with mechanical CAD design and engineering analysis tools (e.g., SolidWorks, NX, ANSYS, COMSOL).
- Understanding of heat transfer fundamentals, fluid mechanics, thermal stresses, and structural mechanics.
- Understanding of piping and pressure-containing component design, including pressure loads, thermal expansion, and mechanical interfaces.
- Knowledge of materials science as it applies to material selection, thermal properties, and structural performance.
Preferred Skills and Experience- Master's degree in Mechanical Engineering, Aerospace Engineering, Nuclear Engineering, or Thermal Sciences.
- Demonstrated experience in heat exchanger design, analysis, manufacturing, and testing.
- Experience with high-temperature (500°C+) systems, including thermal expansion, creep, fatigue, and material compatibility considerations.
- Experience with thermal and structural finite element analysis (FEA) and computational fluid dynamics (CFD).
- Experience designing high-temperature piping systems, manifolds, and associated mechanical components.
- Experience evaluating piping flexibility, thermal stresses, and loads at equipment connections using analytical or simulation tools.
- Familiarity with heat exchanger and piping fabrication methods, including welding, brazing, and other joining processes.
- Experience designing pressure-containing components and familiarity with applicable ASME codes and standards (e.g., ASME BPVC Section VIII, ASME B31.1, or B31.3).
- Experience developing and executing hardware validation tests, including pressure, thermal cycling, and performance testing.
- Understanding of nuclear safety standards, quality requirements, and regulatory considerations.
- Strong communication skills and ability to collaborate effectively across engineering, manufacturing, materials, quality, and testing teams.
