We are seeking an R&D Engineer to develop and validate test methods for advanced heat transfer systems. The R&D engineer executes with collaboration between scientific, engineering, and global test teams to support new product development. The R&D engineer is responsible for tests that characterize thermal, mechanical, electrical, and long-term reliability performance of heat transfer systems.

Key Responsibilities

• Design and develop test methods to evaluate the thermal, mechanical, electrical, rheological, and reliability performance of heat transfer technologies.
• Establish, optimize, and validate test protocols using equipment such as thermal test vehicles, thermal analyzers, mechanical compression systems, rheometers, and environmental chambers.
• Develop and implement automated test sequences and instrument interfaces to improve testing throughput, repeatability, and data integrity.
• Design and validate prototype fixtures that reproduce customer application conditions.
• Write technical reports on test development and test results.

Mechanical & Thermal Characterization

• Evaluate interactions between TIMs and system interfaces, including heat spreaders, heat sinks, power modules, and IGBT/SiC-based packages.
• Investigate anomalous or unexpected test results through root-cause analysis.
• Analyze large and complex datasets to extract key performance metrics and establish statistical confidence in results.
• Partner with materials scientists, design engineers, and product managers to support material formulation and product development decisions.
• Support customer validation testing and application-specific performance evaluations.
• Train laboratory technicians and global test teams to ensure consistent execution.
• Experience with phase-transition heat transfer technologies like heat pipes and vapor chambers is a plus.

Required Qualifications

• Bachelor's degree with 3+ years of experience, or a Master's degree, in Mechanical Engineering, Electrical Engineering, Materials Science, or a related discipline.
• Hands-on experience in thermal, material, electrical, and/or mechanical testing involving multidisciplinary systems.
• Strong foundation in heat transfer, solid mechanics, and materials behavior.
• Proficiency in data analysis and statistical tools such as Python, MATLAB, Minitab.
