Design spacecraft mechanical structures, assemblies, and components with CAD software (Creo)
Generate and maintain engineering and manufacturing documentation such as part drawings, assembly drawings, and bills of materials.
Document design and analysis data in technical reports, presentations, and manufacturing systems.
Apply engineering judgment to make informed decisions when data is incomplete, balancing performance, manufacturability, reliability, and schedule.
Support manufacturing and production teams by providing design intent, resolving build issues, reviewing nonconformance reports, and implementing corrective actions.
Develop tooling, fixtures, and ground support equipment as needed to support integration and test activities.

Required Qualifications:

Bachelor of Science degree in Mechanical Engineering, Aerospace Engineering, or a similar engineering discipline.
12+ years of professional experience in a mechanical engineering role
Demonstrable experience working in the satellite or launch industry maturing designs from initial concepts to detailed manufacturing drawings
Experience working on the mechanical design of optical systems
Familiarity with typical design requirements for space systems
