The Senior Principal Dynamics Engineer is responsible for performing advanced dynamic analysis, optimization, and test support for existing and new aircraft nacelle structures and systems. This role addresses complex structural behavior under combined static, dynamic, acoustic, and high-cycle fatigue loading, including transient events, impact, and flutter. You will collaborate with Design, Systems, Specialty Engineering, Program Engineering, and executive leadership to ensure compliance with structural, performance, and certification requirements across the full product lifecycle.

• Perform detailed dynamic analyses of complex aerospace structures and systems, including modal, frequency response, transient, sonic fatigue, and flutter‑related assessments.
• Develop and apply analytical and numerical models to support structural integrity under combined static, dynamic, and acoustic loading environments.
• Support structural optimization activities to improve weight, durability, and performance while meeting certification and customer requirements.
• Provide technical leadership and guidance from preliminary design through detailed design, test & validation, production support, and in‑service operation.
• Work closely with Design Engineering to influence structural layouts, material selection, and load paths early in the design process.
• Support and interpret component‑ and system‑level test data; correlate test results with analytical predictions and update models as required.
• Collaborate with Systems, Specialty Engineering, Program teams, and executive stakeholders to resolve complex, ill‑defined technical challenges.
• Prepare and present formal technical documentation, including analysis reports, certification substantiation, and presentations for management, customers, and regulatory authorities.

• Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 10 years prior relevant experience in Structural Engineering or an Advanced Degree in a related field and 7 years prior relevant experience in Structural Engineering.
• Prior experience in the Aerospace Industry.
• Experience applying structural dynamics fundamentals.
• Experience with MSC NASTRAN, including SOL 103 (Modal) and SOL 111 (Frequency Response).
• Experience using 3D CAD tools (e.g., UG NX, CATIA, etc.).
• Experience translating and presenting technical concepts in written and verbal form.

• Experience with aircraft nacelle structures, propulsion system interfaces, or acoustic environments.
• Familiarity with certification requirements (e.g., FAA, EASA) related to vibration, fatigue, flutter and bird strike.
• Experience supporting structural dynamics testing and model correlation.
