• Supporting production teams with onsite review and verification as well as providing timely closure of non‑conformance dispositions.
• Support configuration development and trade studies for future spacecraft missions.
• Maintain requirements compliance and verification, hardware delivery schedule, mass budgets and inter‑system collaboration activities.
• Create CAD, manufacturing drawings, specifications, analysis reports, test plans and reports.
• Perform first‑order strength and sizing calculations for structures, working alongside stress and dynamics analysts to document critical strength capabilities.

• B.S. degree in aerospace, mechanical, or civil engineering and 5+ years of experience in aerospace or related structures engineering.
• Strong design and integration skills using 3‑D CAD software (Siemens NX / Fiber Sim preferable).
• Strong understanding of ASME Y14.5 and drafting techniques for component and assembly specifications.
• Ability to effectively work in a multi‑discipline team and provide technical guidance and insight.

• M.S. degree in aerospace or mechanical engineering and/or 7+ years of experience.
• Working knowledge of composite manufacturing methods, material selection, testing, and characterization.
• Experience with FEA/FEM tools like Nastran, ANSYS, FEMAP, Simcenter, etc.
• Experience with composite materials and sandwich construction techniques.
• Experience with vehicle‑level static and vibroacoustic testing.
• Familiarity with aerospace structural analysis methods (Bruhn, Niu, Roark, etc).
