You will advise on data center loop layout, review thermal designs, debug complex issues, and drive designs from concept

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 with data center teams to define end-to-end thermal architecture from building infrastructure through the rack.
• Collaborate with 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; 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 across CDUs, servers, 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 hardware design guidance and tradeoff analysis.
• Mentor and support the growth of junior engineers.

NÜ Metal is CoreWeave’s Hardware New Product Introduction (NPI) team, a multidisciplinary group of mechanical, thermal, electrical, and power engineers that takes new GPU and server platforms from early concept through validation, integration, and large-scale production across our data centers. The team bridges hardware design, manufacturing partners, and data center operations to de-risk new platforms early and ensure each new generation of high-density, often liquid-cooled hardware lands in the fleet reliably, efficiently, and at scale.

What You’ll Do

• 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.
