About the Role

We are seeking a Sr./Staff Reliability Test Engineer with expertise in cold plate systems for direct liquid cooling in high-performance computing, data center, and hyperscale environments. You will define, execute, and report on reliability qualification tests for cold plates, ensuring they meet rigorous performance, durability, and safety criteria aligned with industry best practices and standards including Open Compute Project (OCP) requirements.

Key Responsibilities

• Develop and execute reliability test plans for cold plates, including corrosion testing, pressure cycling, shock, and environmental testing.
• Conduct failure analysis and root cause investigations for leaks, material degradation, and performance issues
• Collaborate with design and manufacturing teams to improve cold plate robustness and reliability
• Evaluate materials (e.g., aluminum, copper alloys, coatings) for corrosion resistance, erosion, and compatibility with coolants
• Analyze test data and field performance to identify reliability risks and recommend design improvements
• Define reliability requirements, validation criteria, and qualification standards
• Support design reviews (DFMEA, PFMEA) with a focus on thermal and mechanical reliability
• Work with suppliers to ensure component quality and reliability compliance
• Develop accelerated life testing methodologies and predictive reliability models
• Document test procedures, results, and engineering recommendations

Required Qualifications

• Master or PhD degree in mechanical, materials, physics, thermal Engineering, or related field.
• 3 years of experience in thermal/mechanical reliability testing of liquid cooling hardware or analogous HVAC/heat exchanger systems.
• Hands-on experience with cold plates (liquid cooled heat exchangers) or heat sinks in high-performance electronics environments.
• Deep understanding of reliability engineering and testing methodologies
• Familiarity with relevant industry standards (ASTM, IEC etc.) for reliability testing.
• Experience in creating or adhering to reliability qualification documentation for hyperscale products or similar use cases.

Preferred Skills

• Experience with cold plates used in data centers, EVs, or power electronics
• Knowledge of coolant chemistries (e.g., water-glycol, dielectric fluids)
• Background in manufacturing processes such as brazing, welding, or additive manufacturing
