About The Position

Shield AI is seeking a hands-on Vibration Test Engineer to join its Mechanical Test team. This role involves validating the next generation of intelligent autonomous systems through rigorous dynamic testing. The team's mission is to inform and improve Shield AI hardware design by quantifying product performance through custom measurement systems, specialized testing, and rigorous analysis. The Vibration Test Engineer will be the team's subject matter expert in vibration and structural dynamics, leading efforts to characterize hardware response, validate analytical models, and ensure products can withstand demanding operational environments. This position requires a passion for structural dynamics, curiosity about complex systems under dynamic loading, and excitement for solving challenging engineering problems in a fast-paced, collaborative environment. The role involves partnering closely with Mechanical Design, Analysis, Flight Test, Manufacturing, and Reliability teams to develop test strategies, investigate failures, and improve hardware performance throughout the product lifecycle. Success requires deep technical expertise in vibration testing, strong analytical thinking, exceptional organization, and the ability to communicate complex technical findings to cross-functional engineering teams.
