- Own, negotiate, and maintain Interface Control Documents (ICDs) and related interface requirements between the spacecraft and launch vehicles, managing changes through formal configuration control.
- Lead launch vehicle compatibility and coordinate integration analyses, including mass, structural loads and coupled loads analysis, environments, thermal, RF, electrical, and separation and deployment.
- Define and track launch-related requirements, verification plans, and mission assurance deliverables, and ensure launch vehicle requirements flow down into spacecraft and ground design.
- Support launch vehicle provider evaluation and selection, including technical assessments, trade studies.
- Lead technical launch readiness reviews, and provide go/no-go technical recommendations to AST leadership.
Requirements
- Bachelor's degree in Aerospace Engineering, Mechanical Engineering, Systems Engineering, or a related technical field required;
