About The Position

Busek is seeking a Senior Structural Analyst / Structural Engineer to join our Design & Analysis Team supporting the development of advanced spacecraft propulsion systems and aerospace hardware. This is one of the most critical engineering needs within the organization as we continue to expand internally and reduce reliance on outsourced structural analysis work. This role is ideal for an engineer who enjoys owning analyses end-to-end, working closely with hardware teams, and solving complex aerospace structural challenges in a fast-paced R&D environment. The selected candidate will perform and lead structural analyses for flight and development hardware using finite element methods (FEM). Analyses include modal, random vibration, sine, and shock environments typically encountered in aerospace applications. Most analyses are performed using ANSYS, though strong fundamentals and relevant aerospace structural experience are valued above specific software expertise. This position works closely with design engineering, systems engineering, and test engineering to support hardware development, qualification testing, requirements verification, and anomaly resolution.

Requirements

Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or related field
Approximately 6+ years of relevant structural analysis experience
Strong understanding of finite element methods and structural dynamics
Experience performing vibration and shock analyses in aerospace or similar high-reliability environments
Experience developing FEM models and interpreting structural results
Strong understanding of materials, structural behavior, and mechanical failure modes
Ability to work independently and own analyses from start to finish
Strong written and verbal communication skills
U.S. Citizenship required
