Principal Customer Systems Engineer – Data Center Liquid Cooling

TeraCule is developing advanced liquid cooling solutions for AI servers, high-density racks, and next-generation data center infrastructure. They are seeking a hands-on technical expert to support North American customers through evaluation, validation, integration, and deployment of liquid cooling solutions.

Responsibilities:

• Serve as the technical interface for North American customers during evaluation, design-in, validation, and deployment of liquid cooling solutions
• Support customer discussions involving CDUs, facility water connections, secondary cooling loops, cold plates, manifolds, quick disconnects, hoses, pumps, filters, heat exchangers, and rack-level cooling architecture
• Identify integration risks before customer design freeze, including pressure drop, flow imbalance, air entrapment, contamination, leakage, coolant compatibility, pump/CDU operating points, and serviceability concerns
• Review and support customer test plans, validation procedures, commissioning requirements, and acceptance criteria
• Analyze lab and customer data, including flow rate, pressure drop, temperature, coolant condition, pump curves, CDU operating conditions, and cold plate thermal performance
• Support technical roadshows, design reviews, and customer-facing presentations for cold plates, CDUs, and rack-level liquid cooling systems
• Translate customer feedback and field issues into clear engineering actions for product, process, quality, and manufacturing teams
• Work closely with Taiwan/Asia-based engineering and manufacturing teams to support issue resolution and customer deployment
• Develop technical documentation, application notes, troubleshooting guides, test reports, installation guidelines, and customer-facing engineering material
• Travel to customer sites, labs, manufacturing partners, and industry events as needed

Requirements:

• Bachelor's degree or higher in Mechanical Engineering, Thermal Engineering, or a related engineering field
• 5+ years of experience in thermal systems, data center infrastructure, liquid cooling, HVAC/hydronics, commissioning, or high-power electronics cooling
• Hands-on experience with several of the following: CDU systems, Direct-to-chip liquid cooling, Cold plates, Manifolds, Quick disconnects, Pumps, Heat exchangers, Facility water loops, Hydronic systems, Flow balancing, Pressure drop testing, Thermal validation
• Ability to troubleshoot real-world system issues using test data, structured problem-solving, and engineering judgment
• Strong customer-facing communication skills, including the ability to explain technical issues clearly in design reviews, validation meetings, and executive-level discussions
• Ability to work independently in a fast-moving environment with high ownership and limited existing process
• Willingness to travel domestically and internationally
• Must already be legally authorized to work in the United States. TeraCule is not able to provide new visa sponsorship for this role at this time
• Direct experience with data center liquid cooling, AI server cooling, HPC cooling, or hyperscale infrastructure
• Experience with CDU, IRHX, rear-door heat exchangers, chilled water systems, facility water systems, or rack-level liquid cooling
• Experience supporting L3/L4/L5 testing, commissioning, deployment, or site-level validation
• Experience with flush/fill/bleed procedures, leak testing, pressure testing, coolant quality control, and field troubleshooting
• Familiarity with BMS, EPMS, PLC/SCADA, VFDs, sensors, controls, or data center monitoring systems
• Experience with CFD or thermal simulation tools such as ANSYS Fluent, Icepak, FloTHERM, STAR-CCM+, OpenFOAM, or similar tools
• Experience working with Taiwan, China, or Asia-based engineering, manufacturing, or supplier teams
• Mandarin Chinese communication ability is highly preferred but not required
