Senior Staff Engineer, Structures and Vibration (6237)

What you'll do:

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. Assess existing profiles and use 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. 
Provide structural guidance on design changes and production issues as needed

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. 

Preferred qualifications:

M.S. or Ph.D. in Mechanical or Aerospace Engineering. 
Experience as the lead structural engineer on a Group 2–5 UAS, rotorcraft, or VTOL aircraft. 
Experience deriving vibration environments from flight test data (PSD analysis, fatigue damage spectrum, test tailoring). 
Experience with modal testing and FEA model correlation. 
Experience leading structural weight reduction programs. 
Experience developing composite allowables (e.g., CMH-17) and knowledge of composite manufacturing processes. 
Familiarity with MIL-HDBK-516, RTCA DO-160, and aircraft structural certification. 
Experience in startup or high-growth defense environments.
