Principal Thermal Systems Engineer, Liquid Cooling

Salary: $106,000 - 146,000 per year Requirements:

• Bachelors degree in mechanical engineering, thermal sciences, controls engineering, or a closely related field.
• At least eight years of relevant engineering, systems integration, or technical product experience.
• Direct experience supporting data centers, mission-critical facilities, or data center cooling products.
• Hands-on background with liquid cooling technologies such as direct-to-chip cooling, immersion cooling, coolant distribution units, or facility water systems.
• Solid understanding of thermal-fluid systems, HVAC equipment, cooling infrastructure, controls, and heat rejection.
• Ability to assess complete thermal management systems rather than isolated components.
• Experience with CFD, ANSYS, thermal modeling, fluid modeling, or system simulation is strongly preferred.
• Absorption cooling experience is highly valued.
• Experience developing system modes, control requirements, or sequences of operation is preferred.
• Commissioning, field validation, troubleshooting, or facility integration experience is strongly valued.
• Strong customer-facing, presentation, written, and verbal communication skills.
• Ability to explain complex technical concepts clearly to both engineering and business audiences.
• Experience influencing technical direction across multiple teams and stakeholders.
• Professional Engineer licensure, advanced technical education, or participation in industry committees is beneficial but not required.
• Willingness to travel domestically and internationally as needed.

• Act as a subject matter expert in advanced data center thermal management and liquid cooling systems.
• Develop integrated cooling concepts covering chips, racks, coolant distribution units, facility water systems, controls, and heat rejection.
• Review system architectures, equipment capabilities, operating modes, control approaches, and performance tradeoffs.
• Conduct or oversee thermal analysis, computational fluid dynamics, modeling, simulation, and equipment assessment.
• Create system documentation, piping concepts, mode tables, control requirements, and operating sequences.
• Support system validation through digital analysis, lab testing, commissioning, and field evaluation.
• Partner with product teams, technical specialists, consultants, customers, and commercial leaders.
• Provide technical input during strategic customer pursuits and commercialization efforts.
• Deliver technical presentations to customers, leadership teams, sales groups, and industry audiences.
• Participate in organizations such as ASHRAE, the Open Compute Project, IEEE, or similar standards groups.
• Translate emerging cooling technologies into reliable, scalable, and market-ready solutions.
