Principal Airframe Design Engineer

At Firestorm, we’re on a mission to revolutionize how defense solutions are designed and delivered. Our goal is to empower U.S. ally nations to effectively deter aggressors—regardless of their defense budget—through innovative, cost‑efficient technologies. We call this vision “democratized deterrence.”As a VC‑backed company at the intersection of defense and Silicon Valley, we’re pioneering the development of mission‑adaptable aerial vehicles that put power back into the hands of operators.

By prioritizing operator effectiveness, we’re 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 cost.

Join us at Firestorm as we redefine defense procurement, making cutting‑edge technology accessible to all at a fraction of the cost.

Firestorm isseekinga highly skilled Principal Airframe Design Engineer to join our innovative engineering team in developing next‑generation UAV systems. Asan Principal 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 isable to lead yourown projects to completion in a fast‑paced environment.

Ideally, you have significant structural airframe design experience and a proven track record completing collaborative projects effectively.

A successful candidate will have proven experience delivering high-performance, mass‑optimized hardware in rapid development environments, witha strong foundationaircraftmechanical design.

Proficiency in 3D CADandfirst‑order hand calculation methods will be keyto 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.
