• 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

Deployment & Field Support

• 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

Internal SME & Cross-Functional Collaboration

• 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
• Train field teams and adjacent groups unfamiliar with liquid cooling practices
