Perform analysis of mechanical components and systems for heat exchangers utilizing CFD and FEA such as Ansys multiphysics, CAD (Solidworks, Creo, or equivalent.
Design, build and test of prototype heat exchanger units for Exowatt’s power conversion units.
Validate models by test and analytical methods
Create detailed engineering drawings and specifications for manufacturing
Collaborate with cross-functional teams, including electrical, controls, thermal, and software engineers
Evaluate and select appropriate materials based on requirements, cost, and sustainability
Design for manufacturability, assembly, and serviceability
Interface with suppliers, manufacturers, and external engineering partners
Participate in design reviews and ensure compliance with industry standards and regulations
Troubleshoot issues during testing and deployment
Requirements
Bachelor's degree in Mechanical Engineering or related field; Master's degree preferred
7+ years of mechanical engineering experience with a focus on thermal-fluid systems with a focus on heat exchanger design, analysis, and development.
