Thermal Controls 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.

• 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.
