About the Role
You will lead end-to-end thermal design, architecture, and validation for AI computing platforms. You will develop air- and liquid-cooling hardware, model thermal and hydraulic performance, run laboratory testing, and integrate production-ready thermal components into servers and racks.
Requirements
- Bachelor’s, Master’s, or Ph.D. in Mechanical Engineering, Thermal Engineering, Aerospace Engineering, or a related discipline.
- 7+ years of hands-on experience in thermal design, CFD modeling, and physical testing of air-cooled and liquid-cooled electronic systems.
- Expertise in designing, selecting, and qualifying cold plates, rack manifolds, fluid tubing, quick disconnects, and coolant distribution units.
- Understanding of flow networks, pressure-drop calculations, hydraulic balancing, and fluid distribution across server racks.
- Knowledge of air-cooled thermal management, fan selection, heat-sink design, and system impedance testing.
- Experience with CFD tools such as Simcenter Flotherm, Flotherm XT, Ansys Icepak, or Ansys Fluent.
- Knowledge of laboratory instrumentation, thermal test vehicles, flow benches, pressure calibration, and leak testing.
- Experience characterizing and stress-testing liquid-cooled hardware.
Responsibilities
- Lead thermal-fluid design and development of liquid-cooling hardware, including cold plates, rack manifolds, quick disconnects, and tubing networks.
- Define and select internal and external coolant distribution units.
- Analyze fluid dynamics and flow networks to balance flow, minimize pressure drop, and prevent flow starvation.
- Evaluate fluid compatibility, materials, corrosion inhibitors, and closed-loop reliability.
- Design and optimize air-cooled solutions including heat sinks, fans, ducting, chassis airflow, and VRM and memory cooling.
- Build 3D CFD models and 1D hydraulic simulations.
- Architect thermal and fluid laboratory setups, instrument test vehicles, and execute performance testing.
- Integrate thermal components into production-ready AI servers and racks.
