Job Summary
Who We Are
At Firestorm were on a mission to revolutionize how defense solutions are designed and delivered. Our goal is to empower U.S. ally nations to effectively deter aggressorsregardless of their defense budgetthrough innovative cost-efficient technologies. We call this vision democratized a VC-backed company at the intersection of defense and Silicon Valley were pioneering the development of mission-adaptable aerial vehicles that put power back into the hands of operators. By prioritizing operator effectiveness were pioneering a new era of aerial vehicle design. We aim to upend the traditional defense procurement model by delivering world-class capabilities at a fraction of the usual us at Firestorm as we redefine defense procurement making cutting-edge technology accessible to all at a fraction of the cost.
About the Role
Firestorm isseekinga highly skilled Principal Airframe Design Engineer to join our innovative engineering team in developing next-generation UAV systems. AsanPrincipal Airframe Design Engineer at Firestorm you willbe responsible forthe designand build efforts of critical flight structures and mechanisms within our product line. You will be given ownership for the hardware product lifecycle of the airframe. You willbe responsible forthe design analysis and oversight of manufacturing and validation of primary structure.
In this role you will play a pivotal role in developing mechanical components and subsystems that satisfy demanding criteria for performance manufacturability and cost. Yourexpertisewill bridge advanced aerospace technology and practical engineering as you collaborate cross-functionally with electrical manufacturing and flight-test teams to ensure seamless integration of mechanical and electromechanical order tobe successful in this role you mustbe someone who isself-motivated adaptable and is able to lead your own projects to completion in a fast-paced environment. Ideally you have significantstructural airframe design experience and a proventrack recordcompleting collaborative projects effectively.
A successful candidate will have proven experience delivering high-performance mass-optimized hardware in rapid development environments witha strong foundationaircraftmechanical 3D CADandfirst-order hand calculation methods will be key to driving innovative solutions that enhance our UAV platform capabilities. As an individual contributor you will directly influence the technical direction of your designs and help shape engineering best practices across projects. You will be engaged in all phases of the development lifecycle from early concepts and prototyping through rigorous testing and production in a fast-moving high-impact setting.
What Youll Do
