Job description

What you will do

Senior Thermal Data Center Systems Engineer responsible for designing thermal subsystems and components within the data center cooling product portfolio. Operates with minimal supervision, determines approaches to thermal solutions, and leads small technical efforts. Demonstrates proficiency across multiple thermal domains and understands the complete thermal chain from server to ambient. Based onsite, minimum 3 days per week at our Advanced Technology and Innovation Center in New Freedom, PA.

• 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.
