Thermal Systems Engineer II

Own thermal subsystem or component designs for data center cooling products (dry coolers, remote condensers, CDUs, cold plate systems)

• Define specifications for thermal features or products; develop test protocols and acceptance criteria

• Lead prototype development and validation activities; develop and execute comprehensive test plans

• Integrate multiple components into subsystem solutions understanding the complete thermal chain

• Participate in process improvement for testing and analysis methods

• Guide and mentor less experienced engineers; represent Engineering in cross-functional activities
