Thermal R&D Engineer

Position Overview

Advantest is a global leader in semiconductor test and measurement solutions. To support nextgeneration test platforms and increasing device power densities, we are expanding our Global Thermal R&D Team to develop advanced cooling technologies.

We are seeking a Thermal R&D Engineer with handson experience in twophase cooling and refrigerationbased systems. This role focuses on the architecture, design, prototyping, and validation of closedloop phasechange cooling solutions for highperformance semiconductor test environments.

The ideal candidate combines strong fundamentals in thermodynamics and heat transfer with practical experience designing and experimentally validating evaporators, condensers, compressors, and refrigerant loops. This is a highly technical, handson R&D role with real product impact.

Key Responsibilities

• Design, develop, and optimize twophase cooling systems, including evaporators, condensers, compressors, and closedloop refrigerant circuits for semiconductor test applications
• Define systemlevel architecture, component specifications, and performance requirements for refrigerationbased and phasechange cooling solutions
• Build and assemble prototype hardware, fluid loops, test rigs, and instrumentation to experimentally evaluate performance
• Plan and execute experiments to characterize thermal performance, pressure drop, stability, and reliability of twophase systems
• Develop and validate analytical, firstprinciples, and simulation models for heat transfer and fluid flow in phasechange systems
• Evaluate refrigerants with respect to performance, operating temperature range, environmental impact, safety, and material compatibility
• Collaborate closely with mechanical, electrical, manufacturing, and system teams to integrate cooling solutions into complex test platforms
• Drive design optimization for efficiency, robustness, manufacturability, and cost
• Contribute to longterm technology roadmaps for advanced thermal and twophase cooling solutions
