Sr. Mechanical Test & Evaluation Engineer

Sr. Mechanical Test & Evaluation Engineer

San Diego, CA

At Firestorm, we are building the future of expeditionary defense manufacturing and autonomous systems. Modern conflict has exposed a fundamental problem: the systems needed most by operators are often too expensive, too slow to produce, and too difficult to sustain estorm 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.

We are looking for builders, operators, and problem-solvers who want to work on meaningful technology with real-world impact.

As a Sr. Mechanical Test & Evaluation Engineer, you will be the cornerstone of our hardware validation process. You will bridge the gap between design and deployment, ensuring our mission‑adaptable UAVs meet the rigorous demands of the field. You will lead the development of testing protocols for advanced airframes and metallic components, utilizing your expertise in material science and structural analysis to drive the safety and reliability of our next‑generation aerial platforms.
