Job Summary

Who We Are
At Firestorm we are building the future of expeditionary defense manufacturing and autonomous systems.

Firestorm exists to change that.
We develop mission-adaptable aerial systems and deployable manufacturing infrastructure designed to put capability directly into the hands of the warfighter. From modular unmanned aircraft to xCell our deployable microfactory our goal is to make defense systems rapidly deployable adaptable and producible at the point of need.
