About The Position

The Junior Thermal Research Engineer is responsible for supporting the design, modeling, and experimental validation of advanced thermal management systems for next-generation electronics cooling applications in data center, semiconductor test and aerospace and defense applications. The role combines thermal system design, modeling, experimentation, and data science techniques, with a focus on enabling faster design cycles and improved system-level insight.

Requirements

• Bachelors or Masters in Mechanical Engineering or a related field.
• 0-2 years of relevant experience or thermal course work.
• Candidates must reside within 60 miles of Lancaster PA to be considered.
• All applicants must be U.S. Persons within the meaning of ITAR. ITAR defines a U.S. Person as a U.S. Citizen, U.S. Permanent Resident, Political Asylee, or Refugee.

Nice To Haves

• Master’s or PhD in Mechanical Engineering or a related field.
• Academic focus in heat transfer, fluid dynamics, and thermal systems.
• Laboratory and experimental research experience.
• Graduate research in thermal-fluid sciences, cooling technologies, or electronics cooling strongly preferred.
• Exposure to data center cooling and/or high-performance electronics thermal management.
• Experience developing reduced-order or surrogate thermal models.
• Knowledge of optimization-driven design methodologies.
• Ability to integrate simulation, modeling, and experimental validation.

Responsibilities

• Support the design and development of thermal management systems, including liquid cooling, two-phase cooling, and heat exchanger based architectures
• Cooling system design including 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)
• Assist in development of computational tools and simulation frameworks (Python, MATLAB) to support engineering decision-making and research activities
• Support prototype development and testbed construction, including integration of thermal systems and measurement capabilities
• Collaborate with senior engineers and researchers to evaluate new cooling technologies, improve system efficiency and performance and identify key design tradeoffs
