Space Environment Engineer

Are you passionate about human space exploration and avionics development? Join our diverse, mission‑driven team!

We need your creativity, teamwork, and diverse perspectives to help build systems that enable space exploration and benefit life on Earth.

Join us as we tackle exciting challenges for NASA’s deep‑space missions. Amentum is NASA’s largest engineering solutions provider, working together with centers across the United States.

The JETS Space Environments team is seeking a Space Environments Engineer to join Intuitive Machines, a teammate company to provide multidisciplinary technical analysis/modeling and systems engineering support to NASA JSC across programs like Moon Base, Artemis, HLS, CLDP, and SR-1.

The Space Environments Engineer will :

Provide support to NASA programs in the definition of natural and induced space environments, including with multidisciplinary analysis and modeling, working in concert with NASA civil servants and designated contractors

Develop and update semi-empirical and theoretical models of processes relevant to spacecraft natural and induced environments

Analyze/model molecular and particulate contamination sources, including lunar dust, and transport from materials outgassing, vacuum venting, and rocket engine and thruster pluming processes onto spacecraft, elements, and payloads

Analyze optical property impacts from molecular and particulate contamination, including lunar dust, and exposure to orbital and lunar surface environments (e.g., to ultraviolet radiation, ionizing radiation, and atomic oxygen)

Analyze/model plasma effects, spacecraft charging, radiation transport and effects on hardware

Assess compatibility of spacecraft hardware with natural and induced space environments

Provide systems engineering support in space environments requirements and verification plan development as well as requirement and verification activities throughout the life of a program

Conduct systems engineering trade studies to identify potential risks and mitigations, evaluate induced environmental hazards between vehicles, and participate in hazard/risk reviews

Participate in programmatic milestone reviews

Perform other duties as required
