Senior Two-Phase Cooling R&D Engineer

advantestcareers; Chandler (AZ); On-site; USD 120,000 - 180,000; Full time

Job summary

Advantest is seeking a Thermal R&D Engineer to develop two‑phase cooling solutions for high‑density semiconductor test platforms at our Lake Forest, CA site. You will architect, prototype, and validate closed‑loop refrigerant systems, evaporators, and condensers while collaborating with cross‑functional teams.

Ideal candidates have a strong thermodynamics background and 5+ years of hands‑on experience in thermal systems, CAD design, and experimental validation.

Qualifications

• Bachelor’s degree in Mechanical Engineering (MS preferred).
• 5+ years designing two-phase or refrigeration-based thermal systems.
• Strong fundamentals in thermodynamics, heat transfer, and fluid mechanics.
• Experience designing and testing evaporators, condensers, and refrigerant loops.
• Proficiency with 3D CAD tools.

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
