Internship Overview:
Intuitive Machines is seeking a motivated and detail-oriented individual to join our Thermal Engineering team as an intern. As a Thermal Engineer Intern, you will support the development, analysis, and validation of thermal control systems for spacecraft and payloads. This internship offers the opportunity to gain hands-on experience working with active and passive thermal systems in support of lunar landers and other spaceflight hardware.
Key Responsibilities:
- Assist in the modeling and analysis of thermal systems using industry-standard tools such as Thermal Desktop or SINDA/FLUINT.
- Support thermal testing, including setup, execution, and data analysis of thermal vacuum (TVAC) and thermal cycling tests.
- Contribute to the design and sizing of thermal hardware such as heaters, insulation, radiators, and heat straps.
- Help generate and maintain thermal engineering documentation including analysis reports, test plans, and interface control documents.
- Collaborate with mechanical, avionics, systems, and test engineering teams to integrate thermal control strategies across the spacecraft.
- Participate in trade studies and reviews to evaluate thermal design approaches and solutions.
Qualifications:
- Currently enrolled in a bachelor’s or master’s degree program in aerospace engineering, mechanical engineering, or a related field. Certifications and associates backgrounds also welcome.
- Strong interest in spacecraft thermal control, thermal modeling, and environmental testing.
- Familiarity with thermal analysis tools (e.g., Thermal Desktop, SINDA, ANSYS) and CAD platforms is a plus.
- Solid understanding of heat transfer principles: conduction, convection, and radiation.
- Effective communication and collaboration skills.
- Willingness to learn in a fast-paced and multidisciplinary aerospace environment.
Benefits:
- Gain practical experience in thermal control design and analysis for spaceflight systems.
- Work with experienced aerospace professionals and expand your technical skillset.
