V-BAT is a Group 3 vertical takeoff and landing (VTOL) unmanned aircraft system in production and deployed with customers worldwide.\nYou will be the structural technical authority for V-BAT. You will own system loads, stress and dynamics analysis, vibration requirements and testing, and weight optimization.\nThis is a high-impact, company-level role. You will develop and define system-level structural requirements, design criteria, analysis methods, and material allowables that will guide structural work across V-BAT. You will also mentor engineers in FEA and structural fundamentals.\nThis role is ideal for engineers with 12-15+ years of experience who have served as the structural lead or technical authority on an aircraft program.\nWhat you'll do:\nDevelop and maintain company structural standards, including design criteria, factors of safety and margin policy, analysis methods, material allowables, and joint design practices. \nOwn V-BAT system loads, and define structural requirements for subsystems, components, and suppliers. \nLead and perform static, stability, modal, dynamic, and fatigue analyses of V-BAT structures using hand calculations and FEA (Simcenter). \nLead composite structural analysis and define composite design requirements. \nServe as the bolted joint expert for the program. \nOwn vibration and shock environments. Assess existing profiles and use measured flight data to develop defensible test requirements. \nDefine and improve vibration test requirements and processes, from test planning through verification, validation, and model-to-test correlation. \nLead a program-wide weight optimization review of existing designs, and analyze new designs for weight efficiency and material selection. \nReview structural analyses, test reports, and design review content, and present findings to engineering leadership and customers. \nMentor engineers in FEA and structural fundamentals, and build the team's structural analysis capability. \nProvide structural guidance on design changes and production issues as needed\nRequired qualifications:\nB.S. in Mechanical Engineering, Aerospace Engineering, or a related discipline. \n12+ years of structural analysis experience on aircraft, UAS, or comparable complex system, including serving as a structural lead or technical authority. \nExperience creating structural design criteria, analysis methods, or engineering standards. \nExpert knowledge of structural mechanics and hand calculations, including strength, stability, fatigue, and structural dynamics. \nExpertise with FEA tools, preferably Siemens Simcenter (Nastran or Femap), or equivalents such as ANSYS or Abaqus. \nSignificant experience analyzing composite aircraft structures and defining composite design requirements. \nExpert-level knowledge of bolted joint analysis and design. \nHands-on experience with vibration and shock testing, including test planning, instrumentation, and data review, plus working knowledge of MIL-STD-810. \nProven track record of mentoring engineers. \nStrong written and verbal communication skills. \nPreferred qualifications:\nM.S. or Ph.D. in Mechanical or Aerospace Engineering. \nExperience as the lead structural engineer on a Group 2-5 UAS, rotorcraft, or VTOL aircraft. \nExperience deriving vibration environments from flight test data (PSD analysis, fatigue damage spectrum, test tailoring). \nExperience with modal testing and FEA model correlation. \nExperience leading structural weight reduction programs. \nExperience developing composite allowables (e.g., CMH-17) and knowledge of composite manufacturing processes. \nFamiliarity with MIL-HDBK-516, RTCA DO-160, and aircraft structural certification. \nExperience in startup or high-growth defense environments.","description_format":"text","description_chars":3906,"description_truncated":false,"requirements":{"experience_years_min":12,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military
