Spacecraft Dynamics Engineer

Overview As a Spacecraft Dynamics Engineer, you own dynamic analysis and vehicle response across our spacecraft. You’ll ensure robustness of hardware through all flight phases by coordinating with structures, test, and systems teams. You’ll develop load cases, run FEM/analytical analyses, and validate against test and flight data. This role puts you at the core of bringing scalable, reliable satellite buses to market, driving improvements in loads methodologies and cross‑functional collaboration. You will work in a fast‑moving startup environment that values impact, mentorship, and hands‑on problem solving.
