Job Summary:
We are seeking a highly skilled and motivated Thermal Engineer to lead the design, development, and validation of two-phase cooling systems for high-performance computing and data center applications. The ideal candidate will have hands-on experience with two-phase cold plates, CDU systems, and boiler plates used in immersion cooling environments.

Key Responsibilities:

• Design and optimize two-phase cold plates and boiler assemblies for immersion cooling applications
• Lead thermal characterization and testing of components under varying heat loads and fluid conditions
• Work with mechanical and systems engineers to integrate cold plates and CDU hardware into rack-scale systems
• Analyze thermal performance using simulation tools (e.g., CFD, FEA) and validate with experimental data
• Collaborate with suppliers and manufacturing teams to support prototype builds and production transfer
• Develop test plans, oversee lab testing, and generate detailed technical documentation and reports
• Contribute to system-level architecture and trade studies involving fluid selection, flow control, and reliability

Qualifications:

• Master's or Doctoral degree in Mechanical Engineering, Thermal Engineering, or related field
• 3+ years of experience in thermal/fluid systems design, ideally with a focus on two-phase flow
• Hands-on experience with cold plate design, CDU integration, and boiling/evaporation heat transfer
• Proficiency in thermal and fluid modeling tools (e.g., ANSYS, FloTHERM, or similar)
• Familiarity with two-phase refrigerants, fluorochemical fluids, or hydrocarbon working fluids
• Strong problem-solving skills and a track record of driving thermal innovation in complex systems
• Excellent communication skills and ability to work in cross-functional teams

Preferred:

• Experience with immersion cooling deployments in data centers or high-power electronics
• Knowledge of reliability, safety, and environmental aspects of two-phase systems
• Prior experience with system commissioning and field support is a plus
