Zone 5 Technologies Tech Stack

Defense UAS and munitions systems from concept through production

Aviation and Aerospace Component Manufacturing San Luis Obispo, CA 201–500 employees Privately Held

Zone 5 Technologies designs and manufactures unmanned aircraft systems and air-launched effects for defense applications, operating as a vertically integrated DoD prime contractor. The tech stack reveals a mature embedded systems operation (MATLAB, Simulink, VxWorks, FreeRTOS, CAN bus) paired with modern web/simulation tooling (React, FastAPI, Three.js), while active adoption of LangChain, Milvus, and pgvector signals a recent shift toward AI-driven mission planning or system autonomy. Engineering dominates the 96-person hiring pipeline, suggesting scaling of flight controls, guidance systems, and production integration as core growth vectors.
