Description:
Core Weave 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.
Responsibilities
About the role:
- 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 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.
- Bachelor’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field
