Hardware Engineer - Liquid Cooling

What You’ll Do:

CoreWeave is seeking a highly skilled and motivated Infrastructure/Hardware Engineer to join our Hardware Engineering team, reporting to the Hardware Engineering Manager. In this role, you will play a crucial part in the design, development, and optimization of our liquid cooling hardware infrastructure. You will collaborate closely with cross-functional teams, external vendors, and stakeholders to ensure the successful delivery of highly performant and reliable hardware solutions.

About the role:

Responsibilities:

• Develop and maintain hardware/firmware management services.
• Automate all aspects of the liquid cooling hardware lifecycle.
• Collaborate with cross-functional teams to define liquid cooling hardware requirements, specifications, and system architecture.
• Create and maintain accurate documentation of liquid cooling hardware designs, specifications, test procedures, and results.
• Analyze and optimize the performance of liquid cooling hardware systems, identify bottlenecks, and propose improvements for enhanced efficiency.
• Establish processes for internal liquid cooling hardware testing, deployment, and performance optimization.
• Optimize,test, and support rack-level liquid cooling solutions, including in-rack CDU (Coolant Distribution Unit) configurations.
• Work with liquid-to-air sidecars and remote CDUs to manage heat rejection and optimize thermal performance.
• Collaborate with data center facilities teams to integrate liquid cooling systems into broader infrastructure designs.
• Develop and implement monitoring, alerting, and control systems for liquid cooling components (e.g., pumps, valves, flow sensors).
• Interface with server vendors and OEMs to validate compatibility of hardware with liquid-cooled chassis and configurations.

Who You Are:

Must have at least 4 years professional experience:

• Hands-on experience with in-rack CDUs, liquid-to-air heat exchangers, or end-of-row cooling units.
• In-depth knowledge of server hardware, components, and management technologies.
• Strong understanding of data center thermal design principles, including air and liquid cooling fundamentals.
• Familiarity with coolant types, thermal transfer mechanisms, and leak detection/mitigation techniques.
• Proficiency in ansible/python and experience with programmatically interacting with hardware using IPMI, SSH, or Redfish (preferably Redfish).
• Proven ability to collaborate with hardware and facility engineering teams to deliver integrated cooling solutions.
• Strong passion for automation and infrastructure scalability, with a commitment to continuous improvement.
• Excellent documentation skills and attention to detail.
• Strong analytical and problem-solving abilities.
