Junior Thermal Research Engineer Eaton

Position: Junior Thermal Research Engineer by Eaton
Job Description Boyd Thermal by Eaton is seeking a Junior Thermal Research Engineer in our Lancaster, PA location.

Primary Function:

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.

This role emphasizes thermal-fluid system modeling, data-driven engineering, and product development to accelerate design, optimization, and system-level performance prediction.

Essential Functions:

The Junior Thermal Research Engineer will work within a multidisciplinary engineering team to develop innovative thermal management and test solutions for high-performance electronics and data center systems.

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.

Qualifications

Basic qualifications:

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., Solid Works 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

Identify key design tradeoffs

Contribute to technical documentation, reports, and presentations of results.
