AI System Engineer - Data Centers

Johnson Controls is a global leader in thermal management and energy efficiency, and they are seeking an AI Systems Engineer for their Data Center Thermal Solutions team. The role focuses on developing and deploying liquid cooling solutions for high-density data centers, requiring strong knowledge of GPU-based AI hardware and thermal management principles.

Responsibilities:

• Design, analyze, and deploy liquid cooling systems (single-phase, two-phase, immersion, and hybrid) for high-density data centers
• Perform thermal modeling, CFD simulations, and performance optimization for CPU and GPU workloads
• Commission and validate CDUs, cold plates, immersion tanks, and thermal test vehicles at lab and facility scale
• Evaluate system resiliency and reliability under operational and failure scenarios
• Collaborate with hyperscalers, OEMs, and partners to align solutions with AI/HPC workload demands
• Contribute to patent filings, publications, and industry standards engagement

Requirements:

• PhD or Master's in Mechanical Engineering or related field
• Proven data center cooling experience, particularly in GPU/AI hardware environments
• Strong knowledge of heat transfer, fluid mechanics, and thermodynamics
• Proficiency in CFD tools (ANSYS, Fluent, Modelica, Icepak, Cadence 6Sigma) and instrumentation for performance validation
• Demonstrated ability to work independently, set priorities, and deliver results with minimal supervision
• Track record of innovation, patents, or technical publications in thermal management
