Nuclear Systems Engineering Intern

Analytical Mechanics Associates•Denver, CO

7d•$25 - $30

About The Position

AMA is currently accepting applications for a motivated intern to support ongoing reactor technology development planning for space reactor applications with a team of engineers beginning Summer 2026. The qualified candidate will be a senior undergraduate or graduate student with research experience related to advanced nuclear systems. A background in reactor design for space nuclear applications, such as nuclear thermal propulsion (NTP), nuclear electric propulsion (NEP), or fission surface power (FSP), is preferred. In addition to completing the application on our website (www.ama-inc.com), candidates selected for an interview will be required to provide two or more references. The hourly rate for this position is $25-$30/hr and is commensurate with experience and education.

Requirements

Completion of at least three years of an undergraduate degree in Nuclear Engineering or a related STEM field with a strong background in reactor/radiation physics.
Experience with using MATLAB, Simulink, C++, or Python for performing engineering analyses.
Self-motivated with good communication skills and desire to work in a highly motivated team environment.

Nice To Haves

Completion of a Bachelor’s degree in Nuclear Engineering.
The ideal candidate would be a graduate student or an undergraduate with prior internship or academic experiences performing nuclear engineering research.
