Key Responsibilities

We are seeking a highly skilled and innovative Senior R&D Thermal Engineer to lead the development of advanced thermal management and integration solutions for xPUs, high-density power supplies and power rack systems for datacenter facilities. The ideal candidate will leverage their expertise in liquid cooling technologies and system integration to design and scale next-generation thermal management concepts. This role requires thermal and mechanical design, hands-on problem-solving, technical leadership, a forward-thinking approach to address the challenges of modern computing infrastructures, and customer on-site technical support.

Innovative Thermal Management Design:

• Develop cutting-edge thermal management concepts to effectively dissipate heat from xPUs, extending and integrating new thermal solutions on converter- and rack-level cooling for datacenters.

Expertise in Liquid Cooling Technologies:

• Design and optimize systems using technologies such as cold plates, liquid cooling, and heat exchangers.
• Investigate and implement emerging cooling techniques, including liquid immersion cooling, microfluidic cooling channels, evaporative cooling, and two-phase cooling systems.

Scalable Solutions:

• Engineer thermal management solutions that scale seamlessly from xPUs to entire power racks and datacenters.

Collaboration and Leadership:

• Work cross-functionally with hardware design teams and business units to align thermal solutions with company goals.
• Mentor and provide guidance to junior engineers in thermal management techniques and system integration principles.

Minimum Qualifications

• Advanced degree (Master's or PhD) in Mechanical Engineering, Thermal Engineering, or a related field.
• Proven experience in developing advanced thermal solutions and integrating them into power electronic systems.
• Deep understanding of cooling technologies, including liquid cooling, two-phase cooling, and heat exchangers.
• Strong background in scaling thermal solutions from component-level to system-level applications.
• Expertise in CFD simulation tools and thermal modeling software (FloTHERM, MacroFlow, ANSYS Icepak).
• Excellent problem-solving skills, with the ability to work on complex, multidisciplinary topics.
• Strong communication and leadership abilities.

Preferred Qualifications

• Experience with innovative cooling materials.
• Understanding of lifecycle assessment (LCA) and environmental impact analysis for cooling solutions.
• Knowledge of industry standards and regulations for datacenter thermal management and power electronic systems.
• Background in system control and coding, enabling integration of thermal–fluid and control simulations.
• Practical understanding of manufacturing processes (e.g., CNC machining, soldering, brazing, welding).
