About the role

Staff Thermal Engineer responsible for architecture and implementation of thermal systems for high-density, GPU-accelerated data centers, including rack- and server-level cooling, collaboration with data center teams and hardware platforms, and driving designs from concept to production.

Responsibilities

  • Own the architecture, design, and evolution of thermals for high-density, GPU-accelerated data centers.
  • Design, validate, and optimize rack-level and server-level thermal solutions.
  • Partner closely with data center teams to define end-to-end thermal architecture—from building infrastructure through the rack.
  • Collaborate with world-class engineers developing next-generation AI/ML hardware platforms.
  • Advise on data center secondary loop layout, commissioning, and operation
  • Review and evaluate JDM/ODM thermal designs, including thermal simulations; independently run simulations as needed.
  • Debug complex thermal and system-level issues, incorporating learnings into future designs.
  • Collaborate with vendors and internal teams to manage heterogeneous deployments, ensuring a cohesive thermal strategy across varying CDUs, server platforms, and facilities.
  • Drive thermal designs from early concept through mass production.
  • Ensure designs meet high standards for efficiency, safety, reliability, and scalability.
  • Partner with manufacturing teams to support production readiness and ramp.
  • Actively contribute to architectural discussions, providing strong hardware design guidance and tradeoff analysis.
  • Mentor and support the growth of junior engineers.

Qualifications

  • 10+ years of thermal management experience
  • Bachelor’s Degree in Mechanical Engineering, Aerospace Engineering, or a related technical field
  • Experience in heatsinks, thermal interface materials, liquid cooling, heat exchangers and fans
  • 10+ years of experience designing complex thermal systems for hyperscale data centers
  • Experience in liquid cooled data center architectures, including cold plates, wetted material compatibility, and CDUs
  • Strong thermal design expertise
  • Experience leading cross-functional design efforts in fast-paced environments
  • Strong documentation and design review practices
  • Excellent negotiation and stakeholder-management skills
  • Understanding of rack-level thermal requirements and their impact on upstream infrastructure, including CDUs, facility piping, and chillers
