Principal Stress Engineer IV(Onsite)
About The Position
The Principal Stress Engineer supports the design and certification of aircraft interior monuments, including lavatories, crew rests, galleys, stowage units, closets, partitions, and other cabin furnishings. The role is responsible for structural analysis, certification substantiation, and load development to ensure compliance with regulatory and customer requirements. It requires expertise in finite element analysis (FEA) and preparation of technical documentation supporting aircraft certification programs. The position is onsite in Everett, Washington. The successful candidate will work with design engineers, certification specialists, manufacturing engineers, suppliers, and customers to address technical issues, support design reviews, and recommend structural solutions that optimize weight, manufacturability, and certification compliance. The role requires a U.S. Person; no security clearance is required.
