Responsibilities include but are not limited to:

Lead design, development, and testing of heat exchangers and related thermalfluid systems, driving successive design iterations toward improved effectiveness, cost, and manufacturability
Develop system requirements, specifications, and design documentation for heat exchanger cores and assemblies
Design and optimize heat exchanger geometries and components - including cores, headers, manifolds, tube sheets, and mounting/support structures - balancing thermal effectiveness against pressure drop, mass, and volume
Select appropriate materials for applications considering thermal cycling, creep, fatigue, and corrosion resistance
Create detailed engineering drawings and models using 3D CAD software with proper GD&T per ASME Y14.5 standards
Lead and participate in component and system level testing, including test planning, execution, and thermal/hydraulic data reduction and correlation to analytical predictions
Troubleshoot design and operational issues (e.g., thermal stress, flow maldistribution, fouling, leakage) with calculated risk assessment
Collaborate with manufacturing and quality teams to ensure producibility of designs, including brazed, welded, and additively manufactured cores
Interface with various engineering disciplines to ensure proper thermal and system integration
