Job Description

Position Overview: Advantest is a global leader in semiconductor test and measurement solutions. To support next‐generation 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 hands‐on experience in two‐phase cooling and refrigeration‐based systems. This role focuses on the architecture, design, prototyping, and validation of closed‐loop phase‐change cooling solutions for high‐performance 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, hands‐on R&D role with real product impact.

Key Responsibilities:

Design, develop, and optimize two‐phase cooling systems, including evaporators, condensers, compressors, and closed‐loop refrigerant circuits for semiconductor test applications
Define system‐level architecture, component specifications, and performance requirements for refrigeration‐based and phase‐change 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 two‐phase systems
Develop and validate analytical, first‐principles, and simulation models for heat transfer and fluid flow in phase‐change 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 long‐term technology roadmaps for advanced thermal and two‐phase cooling solutions

Job Requirements:

Qualifications & Experience Required
Bachelor's degree in Mechanical Engineering or related field (Master's degree preferred)5+ years of experience designing and developing two‐phase or refrigeration‐based thermal systems
Strong understanding of thermodynamics, heat transfer, and fluid mechanics, particularly for phase‐change systems
Practical experience with compressor selection, evaporator/condenser design, and system‐level performance optimization
Hands‐on experience assembling and testing fluid loops, refrigeration systems, or thermal prototypes
Proficiency with 3D CAD tools (SolidWorks or equivalent)
Strong analytical, problem‐solving, and communication skills
PreferredExperience with pumped refrigerant loops, vapor‐compression systems, or thermosiphons
Familiarity with thermal/CFD simulation tools (Solidworks, ANSYS, FloEFD, or similar)
Experience working in semiconductor, electronics cooling, or high‐power systems

Role Details:

On‐site 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 next‐generation device capabilities. You'll collaborate with a global R&D organization, influence future product platforms, and help define new approaches to two‐phase cooling in demanding, real‐world applications.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
