• Lead the design and development of advanced cold plates, including high-performance internal structures and thermal enhancement features.
• Develop innovative cold plate architectures to support increasing heat flux requirements and next-generation processor platforms.
• Collaborate with thermal engineers to optimize thermal resistance, pressure drop, manufacturability, and system integration.
• Develop innovative coolant flow path designs and manifold architectures to improve cooling efficiency and flow distribution.
• Optimize internal channel structures, flow balancing strategies, and pressure drop performance through simulation and experimental validation.
• Apply CFD analysis and design methodologies to achieve superior thermal-fluid performance.
• Lead the development and qualification of new cold plate joining technologies, including vacuum brazing, laser welding, friction stir welding, diffusion bonding, and other advanced manufacturing processes.
• Collaborate with suppliers and manufacturing teams to evaluate process capability, reliability, and scalability.
• Drive process innovation to improve product performance, yield, and production efficiency.
• End-to-End Product Development: Lead product development from concept, prototype, design validation, and qualification through mass production.
• Establish design verification plans, reliability requirements, and manufacturing readiness criteria.
• Drive DFM, DFA, and cost optimization activities throughout the product lifecycle.

What We're Looking For

• Bachelor’s or Master’s degree in mechanical engineering, Thermal Engineering, or a related field.
• 7–10+ years of experience in thermal and mechanical design.
• Proficiency in CAD software (e.g., NX, Creo, SolidWorks).
• Familiarity with End-to-End Development (Concept to Production).
• Experience with manufacturing processes (CNC machining, stamping, plating, injection molding, LSR molding, Rubber Molding Process).
• Experience with mechanical & thermal design and testing requirements.
• Excellent problem-solving and analytical skills, able to deeply analyze testing failure modes with a focus on manufacturability and quality control.
• Demonstrated experience working with cross-functional teams in English.
• Tolerance stack-up analysis for CAD and product specification definition, review thermal and reliability testing report.

Nice to Have

• Hands-on experience in advanced cold plate design and liquid cooling product development.
• Strong knowledge of coolant flow path optimization, manifold architecture design, and CFD analysis.
• Experience with advanced joining technologies such as vacuum brazing, laser welding, diffusion bonding, friction stir welding, or seal welding.
• Experience developing liquid cooling solutions for AI servers, data centers, HPC, or telecom infrastructure.
• Deep understanding of heat transfer, fluid dynamics, thermal interface materials, and cooling system reliability.
• Proven track record in bringing innovative thermal products from concept to mass production.
