TL;DR · Principal Thermal Engineer

The Principal Thermal Engineer joins the Packaging Engineering team to address complex thermal challenges for the Qualcomm Dragonfly AI300 platform and future AI computing systems. This role involves leading thermal architecture solutions, performing simulations from silicon to data center environments, and conducting laboratory tests to validate models. The engineer will drive strategy discussions, perform thermal design reviews, and analyze results to ensure performance and reliability. Key technical requirements include proficiency in computational fluid dynamics (CFD) tools like ANSYS Icepak, Celsius EC, or Flotherm, alongside scripting in Python, C/C++, or MATLAB. Candidates must understand thermal interface materials, heat sinks, vapor chambers, and 2.5D or 3D package architectures. The work focuses on cooling high-power processors, GPUs, and AI accelerators within high-performance computing and data center environments.

What you'll do

  • Lead thermal architecture solutions through simulation and test across various stakeholders.
  • Perform thermal simulations using CFD tools from silicon to data center environments.
  • Drive strategy discussions and conduct thermal design reviews and presentations.
  • Conduct thermal tests to validate and characterize models.
  • Analyze and document simulation and test results throughout the product development phase.
  • Correlate simulation models with empirical test results to improve model accuracy.
  • Design and execute thermal validation experiments in a laboratory environment.

What we're looking for

  • Bachelor's degree in Chemical, Electrical, or Mechanical Engineering with 8+ years of System/Package Design/Technology Engineering experience.
  • Master's degree in Chemical, Electrical, or Mechanical Engineering with 7+ years of System/Package Design/Technology Engineering experience.
  • PhD in Chemical, Electrical, or Mechanical Engineering with 6+ years of System/Package Design/Technology Engineering experience.
  • 10+ years of industry experience in electronics cooling for high-performance computing, AI, or data center products (preferred).
  • Experience developing thermal solutions for high-power processors, GPUs, or AI accelerators using air, liquid, or hybrid cooling (preferred).
  • Proficiency in CFD analysis using tools such as ANSYS Icepak, Celsius EC, or Flotherm (preferred).
  • Proficiency in scripting and programming for data analysis and model automation using Python, C/C++, or MATLAB (preferred).
  • Experience with advanced semiconductor packaging technologies, including 2.5D and 3D package architectures (preferred).
