Staff Thermal Engineer

About the role

NÜ Metal is CoreWeave’s Hardware New Product Introduction (NPI) team. Our multidisciplinary group of mechanical, thermal, electrical, and power engineers take new GPU and server platforms from early concept through validation, integration, and large-scale production across our data centers.

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.
• 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.
