NVIDIA’s AI Factories rely on advanced physics-based digital twins to design, validate, and optimize cooling infrastructure for the next generation of accelerated computing. We are seeking a PhD-level intern to drive R&D in single-phase and two-phase cooling digital twin development, creating high-fidelity SimReady assets and contributing to the next wave of intelligent AI Factory infrastructure.

‍

‍

What You Will Be Doing:

‍

• Develop high-fidelity CFD and thermo-fluidic models for single-phase and two-phase cooling systems in data centers, including cold plates, immersion, air cooling, and facility liquid cooling systems.
• Build SimReady geometries and metadata for use in NVIDIA’s Omniverse platform using USD-based workflows.
• Use Cadence, ANSYS Fluent, STAR-CCM+, Flownex, or equivalent tools to build and validate digital twin components.
• Automate simulation workflows using Python, including parameter sweeps, sensitivity studies, multiphysics coupling, and surrogate model generation.
• Chip in to multi-domain digital twins spanning thermal, mechanical, electrical, and control systems.
• Integrate simulation data with Omniverse extensions and collaborate on R&D-grade digital twin workflows.
• Work with the entire NVIDIA Data Center Engineering (DCE) team across cooling, power, controls, and architecture.
• Validate simulations with lab and field data and define performance envelopes for cooling technologies.

‍

What We Need to See:

‍

• Pursuing PhD in Mechanical Engineering, Thermal Sciences, Computational Engineering, or closely related field.
• Solid understanding of thermofluid dynamics, single- and two-phase heat transfer, and data center cooling systems.
• Experience with CFD tools such as Cadence, Ansys Fluent, STAR-CCM+, or similar.
• Experience with flow network modeling tools such as Flownex.
• Strong programming ability in Python.
• Experience with USD, SimReady standards, or Omniverse workflows.

‍

Ways to Stand Out from the crowd:

‍

• Experience in two-phase digital twin modeling familiarity with predictive digital twins or integrating ML/AI with physics-based models.
• Experience developing custom Omniverse extensions or simulation automation tools.
• Publications or research in thermal management or digital twins.
