Our world-class team includes experts in all aspects of spacecraft subsystems design, development, and test, on-orbit operations, and safety.

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.
• Participate in real missions and contribute to hardware bound for the Moon.
• Receive mentorship and career development support during your internship.
