Job Level
Tech Stack
About the role
- Lead technical discovery sessions with customers to gather thermal, environmental, mechanical, and operational requirements
- Design end‑to‑end liquid cooling solutions featuring rear‑door heat exchangers, CDUs, manifolds, hoses, fittings, and facility water loop considerations
- Produce detailed solution designs including schematics, BOMs, system flow diagrams, thermal performance expectations, and installation guidelines
- Translate customer requirements into scalable, supportable, and reliable architectures
- Support field engineering teams during installation, commissioning, and validation of RDHx and CDU systems
- Provide technical oversight on-site or remotely, ensuring the deployed system aligns with the approved design
- Troubleshoot flow rates, pressure drops, temperature deltas, coolant quality, sensor behavior, and CDU operational parameters
- Assist with acceptance testing, monitoring configurations, and integration with facility cooling infrastructure
- Serve as the internal authority on liquid cooling within engineering, operations, sales, and product
- Develop internal documentation: reference architectures, best practices, safety guidelines, and deployment playbooks
- Define standards and repeatable processes for liquid cooling implementations.
- Contribute to service offerings that support deployment, maintenance, and ongoing optimization of liquid cooling systems.
Requirements
- 7+ years in data center infrastructure, solutions architecture, mechanical/thermal engineering, or HPC environments
- Hands-on experience with: Rear-door heat exchangers (enclosed or active systems)
- Cooling Distribution Units (CDUs), Secondary Fluids Network (SFN) design and fabrication
- Coolant loop design, manifolds, flexible hose routing, connectors, drip-less fittings, sensors, etc.
- Rack and system level liquid cooling technologies, including multiple cooling loops, and direct-to-chip cooling
- Strong understanding of: Heat transfer, thermodynamics, and fluid mechanics
- Facility water loops and integration points
- Flow balancing, delta-T analysis, and pump performance curves
- Leak detection and safety best practices
- Familiarity with data center power/cooling concepts (rack-level thermals, airflow management).
Benefits
- Health insurance
- 401(k) matching
- Flexible work hours
- Paid time off
- Remote work options
