Job description

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

Qualifications & ExperienceRequired

  • Bachelor's degree in Mechanical Engineering or related field (Master's degree preferred)
  • 5+ years of experience designing and developing twophase or refrigerationbased thermal systems
  • Strong understanding of thermodynamics, heat transfer, and fluid mechanics, particularly for phasechange systems
  • Practical experience with compressor selection, evaporator/condenser design, and systemlevel performance optimization
  • Handson experience assembling and testing fluid loops, refrigeration systems, or thermal prototypes
  • Proficiency with 3D CAD tools (SolidWorks or equivalent)
  • Strong analytical, problemsolving, and communication skills

Preferred

  • Experience with pumped refrigerant loops, vaporcompression systems, or thermosiphons
  • Familiarity with thermal/CFD simulation tools (Solidworks, ANSYS, FloEFD, or similar)
  • Experience working in semiconductor, electronics cooling, or highpower systems

Role Details

  • Onsite position at Advantest's Lake Forest, CA facility
  • Up to 10% domestic and international travel

Why Advantest?

This role offers the opportunity to work at the forefront of advanced thermal management for semiconductor testing, where cooling performance directly enables nextgeneration device capabilities. You'll collaborate with a global R&D organization, influence future product platforms, and help define new approaches to twophase cooling in demanding, realworld applications.
