## Description

Shield AI is seeking a Senior Staff Structural Analysis & Vibration Engineer to serve as the structural and vibration subject-matter expert (SME) for V-BAT, a Group 3 vertical takeoff and landing (VTOL) unmanned aircraft system.

You will be the structural technical authority for V-BAT, owning system loads, stress and dynamics analysis, vibration requirements and testing, and weight optimization.

Key responsibilities:

- Develop and maintain company structural standards, including design criteria, factors of safety and margin policy, analysis methods, material allowables, and joint design practices.

- Own V-BAT system loads, and define structural requirements for subsystems, components, and suppliers.

- Lead and perform static, stability, modal, dynamic, and fatigue analyses of V-BAT structures using hand calculations and FEA (Simcenter).

- Lead composite structural analysis and define composite design requirements.

- Serve as the bolted joint expert for the program.

- Own vibration and shock environments, assessing existing profiles and using measured flight data to develop defensible test requirements.

- Define and improve vibration test requirements and processes, from test planning through verification, validation, and model-to-test correlation.

- Lead a program-wide weight optimization review of existing designs, and analyze new designs for weight efficiency and material selection.

- Review structural analyses, test reports, and design review content, and present findings to engineering leadership and customers.

- Mentor engineers in FEA and structural fundamentals, and build the team's structural analysis capability.

Required qualifications:

- B.S. in Mechanical Engineering, Aerospace Engineering, or a related discipline.

- 12+ years of structural analysis experience on aircraft, UAS, or comparable complex system, including serving as a structural lead or technical authority.

- Experience creating structural design criteria, analysis methods, or engineering standards.

- Expert knowledge of structural mechanics and hand calculations, including strength, stability, fatigue, and structural dynamics.

- Expertise with FEA tools, preferably Siemens Simcenter (Nastran or Femap), or equivalents such as ANSYS or Abaqus.

- Significant experience analyzing composite aircraft structures and defining composite design requirements.

- Expert-level knowledge of bolted joint analysis and design.

- Hands-on experience with vibration and shock testing, including test planning, instrumentation, and data review, plus working knowledge of MIL-STD-810.

- Proven track record of mentoring engineers.

- Strong written and verbal communication skills.
