About this role
Junior Thermal Research Engineer
A global leader in Laconia, NH is seeking a Junior Thermal Research Engineer for their team. This full-time, direct-hire role will assist with the design, modeling, and experimental validation of innovative thermal management and test solutions for high-performance electronics and data center systems.
Responsibilities of the Junior Thermal Research Engineer
- Support the design and development of thermal management systems, including liquid cooling, two-phase cooling, and heat exchanger-based architectures
- Design cold plates, cooling distribution units (CDUs) and passive two-phase solutions (heat pipes and vapor chambers)
- Develop and apply thermal-fluid modeling tools (steady-state and transient) for system-level performance prediction, including pressure drop, heat transfer, and coolant distribution
- Implement and use machine learning, AI and data-driven methods
- Support data center cooling system modeling, including rack-level and component-level thermal architecture analysis
- Conduct design of experiments (DOE) and support experimental testing, including instrumentation, data acquisition, and validation of models
- Create and maintain CAD models and engineering documentation (e.g., SolidWorks designs, P&IDs, drawings, and test plans)
Qualifications of the Junior Thermal Research Engineer
- Focus or coursework in heat transfer, fluid dynamics, or thermal systems required; graduate research experience in thermal-fluid sciences or cooling technologies strongly preferred
- Technical skills including two-phase cooling, electronics cooling, refrigeration/HVAC systems, ANSYS (Fluent, Icepak, Mechanical) or similar CFD tools, and system-level thermal-fluid modeling
- Programming experience including Python and/or MATLAB for modeling, simulation, and data analysis
- Must be a U.S. citizen
