• Lead applied materials and metallurgical R&D for liquid cooling devices, driving material selection, innovation, and performance trade-offs for next‑generation AI computing systems.
• Design and execute experimental test programs to evaluate materials, joints, coatings, and surface treatments under high heat flux, thermal cycling, pressure, and coolant exposure.
• Investigate materials‑related failures and anomalies in prototypes and early builds, performing root cause analysis and translating findings into design and process improvements.
• Collaborate with mechanical, thermal, R&D, and manufacturing engineers to co‑develop cooling hardware concepts, ensuring materials considerations are embedded early in the design cycle.
• Explore and qualify new materials, alloys, and manufacturing technologies that improve thermal performance, reliability, or scalability of liquid cooling solutions.
• Document research findings and communicate technical recommendations to guide product architecture, design decisions, and future R&D roadmaps.

• Bachelor’s degree in Materials Engineering, Metallurgical Engineering, Material Science or a closely related field.
• Minimum 5 years of experience in materials or metallurgical R&D.
• Experience with application‑specific materials characterization such as defining chemical compatibility/interactions, erosion‑corrosion thresholds, physical properties, etc.
• Practical experience with materials manufacturing, forming, and bonding.
• Extensive hands‑on experience in a laboratory environment.
• Proven ability to collaborate with mechanical and thermal engineers to influence component design, material specs, and validation plans.
• Excellent communication skills, including the ability to write reports and present technical concepts to diverse internal and external audiences.

• Master’s degree or PhD with a relevant specialization is preferred.
• R&D experience involving thermal management or fluid‑exposed systems.
• Proficiency with hand tools, fabrication equipment, instrumentation, data acquisition, modification, and physical testing of prototypes.
• Familiarity with CAD tools such as SOLIDWORKS for designing components or fixtures for testing.

• Well organized, clear communication in English, time management skills.
• Work in a fast‑paced environment.
• Creative, out‑of‑the‑box thinker that thrives in uncertainty.
