Staff Thermal Engineer

About the role

NÜ Metal is CoreWeave’s Hardware New Product Introduction (NPI) team, a multidisciplinary group of mechanical, thermal, electrical, and power engineers.

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.

Requirements

• Minimum Qualifications: 10+ years of thermal management experience, Bachelor’s Degree in Mechanical Engineering, Aerospace Engineering, or a related technical field.
• Preferred Qualifications: 10+ years of experience designing complex thermal systems for hyperscale data centers, experience in liquid cooled data center architectures, 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.
