The Junior Thermal Systems Engineer supports the design, analysis, and testing of thermal management systems for aerospace applications, including cabin comfort systems, avionics cooling loops, and payload thermal regulation. Working under the guidance of senior engineers, this early-career role involves assisting with modeling heat transfer performance, supporting component integration, and preparing documentation to meet aerospace requirements for safety, reliability, and environmental compliance.
Key Responsibilities:
Support the design and development of thermal systems and subsystems for cabin, avionics, or mission payloads
Assist in performing heat transfer and fluid flow analyses (conduction, convection, radiation) under steady-state and transient conditions
Contribute to thermal models and simulations using tools such as MATLAB, Simulink, or basic CFD software
Prepare thermal interface control documentation and assist in system layout reviews
Analyze test data from thermal vacuum tests, environmental chambers, or airflow rigs to evaluate cooling performance
Help develop bill of materials (BOM), component datasheets, and engineering change orders (ECOs)
Work with cross-functional teams including mechanical design, ECS, electrical systems, and integration
Support troubleshooting of thermal anomalies and contribute to design updates or mitigations
Assist in generating compliance documentation and certification materials
Key Focus Areas:
Thermal control for aerospace systems and subsystems
Analysis and modeling of heat transfer and airflow
Support of component-level and integrated system thermal testing
Collaboration across engineering disciplines
Qualifications & Skills:
Education:
Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or closely related discipline (required)
Coursework or internship experience in heat transfer, thermodynamics, or fluid mechanics (preferred)
Experience:
0–2 years of experience in a thermal, HVAC, or aerospace engineering role
Internship or co-op experience with thermal analysis or aerospace systems is a plus
Technical Skills:
Basic understanding of heat transfer, fluid dynamics, and thermodynamics
Exposure to tools such as MATLAB, Excel, Simulink, or thermal modeling software (e.g., Thermal Desktop, COMSOL, or ANSYS)
Familiarity with CAD software (SolidWorks, Creo, or CATIA) and basic drafting practices
Soft Skills:
Strong problem-solving skills and curiosity in applied thermal sciences
Good technical writing and verbal communication
Eagerness to learn and contribute in a fast-paced, collaborative environment
Organized and detail-oriented approach to technical work
