Experience translating and presenting technical concepts in written and verbal form.

Nice To Haves

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 stike.
Experience supporting structural dynamics testing and model correlation.

Responsibilities

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.
