Product Engineer

Responsibilities AND Duties

Responsible for structural design, improvement, and standardization of products such as butterfly valves, ball valves, balancing valves, with a focus on stainless steel valves used in liquid cooling systems. Complete product selection, material selection, 3D modeling (Inventor), and output of engineering drawings based on project requirements. Perform structural calculations, strength checks, flow resistance analysis, and reliability optimization for key valve components (valve body, valve seat, valve stem, seals, etc.). Prepare and maintain technical documents, including: BOM, technical specifications, design changes (ECN), test standards (DVP), assembly drawings, and technical process requirements. Provide technical support for product prototype trials, track tests (pressure resistance, sealing, lifespan, torque, flow, etc.), and promote design optimization. Develop valve design input requirements based on application scenarios (liquid cooling, HVAC, etc.), ensuring products comply with relevant national/industry standards (such as GB, ASME, ISO, DIN). Support the procurement team in supplier development and technical evaluation, and participate in sampling and quality control of castings, forgings, and machined parts. Assist the quality, production, and after-sales teams in resolving technical issues during valve production and at customer sites. Participate in cost optimization (VAVE) projects, promoting structural optimization and material substitution.

EDUCATION: Bachelor’s degree or above in Mechanical Engineering, Fluid Machinery, Process Equipment, or related fields. MANAGEMENT: NA
