Job Type: Full-time

Job Location: Taiwan

Required experience: 5+ years of thermal mechanical test experience.

Responsibilities

• Lead and mentor a team of test engineers and technicians responsible for validation and qualification of passive cold plate solutions and rack-level liquid cooling hardware.
• Plan and execute comprehensive test strategies and qualification plans to meet internal requirements and customer defined standards.
• Drive qualification of passive cold plates, rack manifolds, and fluid distribution components across multiple coolants, covering thermal performance, fluid dynamics, reliability, and mechanical integrity.
• Define and execute stress, reliability, and durability test campaigns including HALT, thermal cycling, temperature stress, pressure, flow, vibration, mechanical load, and leak testing based on risk and field-use conditions.
• Review designs, materials, and specifications to identify technical risks, define mitigation strategies, and recommend design improvements to prevent field failures.
• Detect design and manufacturing defects through structured testing and data analysis; perform root cause analysis and support corrective actions.
• Verify mechanical integrity, sealing performance, and thermal performance for liquid cooling products under realistic operating and stress conditions.
• Collaborate closely with design, reliability, manufacturing, and supplier teams to drive design-for-test and design-for-reliability throughout the product lifecycle.
• Present technical findings and qualification results to internal leadership and external customers; participate in technical reviews and project meetings.

Basic Qualifications

• BS or MS in Mechanical Engineering, Electrical Engineering, Materials Engineering, or a closely related technical field.
• 5+ years of relevant industry experience in thermal-fluid systems, liquid cooling hardware, or electromechanical testing, including 2+ years in a technical leadership or test lead role.
• Strong fundamentals in heat transfer, fluid dynamics, and thermo-fluid behavior.
• Hands-on experience testing and qualifying mechanical and electromechanical components.
• Proven experience executing stress, reliability, and durability testing.
• Solid understanding of failure mechanisms in thermal-fluid hardware, including fatigue, creep, corrosion, erosion, material compatibility, sealing performance, and joint integrity.
• Working knowledge of materials behavior in liquid cooling environments (polymers, elastomers, metals), including aging, chemical compatibility, and thermal degradation.
• Familiarity with relevant industry test standards (ASTM, IEC, ISO) and applying them to build robust qualification methodologies for data center liquid cooling products.
• Proficiency with CAD tools such as SolidWorks (or equivalent) for test fixture design, failure analysis, and test setup definition.
• Experience leading cross-functional validation efforts with design, reliability, materials, and manufacturing teams to drive design-for-reliability improvements early in development.

Preferred Qualifications

• Experience with data center liquid cooling systems.

• Familiarity with rack-level cooling infrastructure such as manifolds, hoses, quick disconnects, and fittings.

• Background in thermal testing.

• SKILLS:

• Ability to manage multiple test programs, priorities, and timelines effectively.

• Strong leadership and mentoring skills with the ability to guide and develop engineers and technicians.

• Excellent problem-solving and analytical skills, especially for failure analysis and root cause investigations.

• Clear and professional communication skills for presenting technical content to diverse stakeholders.
