Built in America · Sedro-Woolley, Washington
Aerostructures, tooling, munitions and marine. Built in America.
Janicki is one of the largest independent aerostructures manufacturers in America: Tier 1, sole source on a range of platforms, family and employee owned. We take aerostructures, tooling, munitions structure and marine hardware from R&D and process development through full-rate production, under our own roofs in Washington, Utah and soon Montana. Built by Americans, for the American warfighter and its Allies.

Ownership
Family and employee owned. Independent. Built for the long term. Janicki is owned by the family whose name is on the building and the people who work in it. That is rare in aerostructures, and it is why the company can plan in decades.
For customers that means schedule control and a supplier that will be here for the life of the program, with tooling, structure and inspection decided by the people building them.

Work you can point at.
Four product lines, six sites, and a company that promotes from within.
Hard problems at production rate
Janicki does the process development and the rate production, so the engineer who qualifies a part is still around when it is built every day.
You own a piece of it
Employees hold shares in the company through an employee stock ownership plan (ESOP), alongside the founding family and at no cost to them, so when the company does well the people who built the parts share in it.
Four product lines, one badge
Move between aerostructures, tooling, munitions and marine without changing employers.
