Thermal R&D Engineer

Job Overview

Advantest America is a leading provider of semiconductor test and measurement solutions. As part of our commitment to innovation, we are expanding our Global Thermal R&D Team to advance next-generation cooling technologies for semiconductor testing.

We are seeking a highly motivated and experienced Thermal-Mechanical R&D Engineer with expertise in two-phase cooling systems. This role offers a unique opportunity to design, build and validate advanced thermal solutions involving evaporators, condensers, compressors, refrigerant loops and fluid management systems for high-performance semiconductor test environments. The ideal candidate will combine strong theoretical knowledge with hands-on design and experimental skills to push the boundaries of thermal management technologies.

Essential Duties & Responsibilities

• Design and develop two-phase cooling systems, including evaporators, condensers, compressors, and closed loop refrigerant circuits for semiconductor test applications.
• Define system architecture, component specifications, and performance requirements for pumped refrigeration-based and phase-change cooling solutions.
• Build and assemble test rigs, mechanical fixtures, fluid loops, and prototype hardware to evaluate thermal system performance.
• Execute experiments to characterize thermal performance, pressure drop, and reliability of two-phase systems.
• Develop and validate analytical and simulation models for heat transfer and fluid dynamics in two-phase systems.
• Evaluate refrigerant types, properties, environmental considerations, and compatibility with components and materials.
• Collaborate with cross-functional teams to integrate cooling solutions into complex test platforms.
• Optimize system designs for efficiency, manufacturability, and cost-effectiveness.
• Support technology roadmap development for advanced cooling solutions.
