Modular autonomous drones and deployable microfactories for defense
Firestorm builds modular unmanned systems for U.S. defense customers, pairing embedded firmware work (C++, Rust, RTOS, CAN-FD, MISRA C) with an in-house production software layer called Crucible spanning MES, MRP and supply chain. Hiring is accelerating and heavily senior engineering, while job posts repeatedly cite slow, expensive production, pointing to manufacturing software and field-deployable factories as the core bet.
Notable leadership hires: Business Development Director, Chief of Staff, Chief Engineer
Firestorm is a San Diego-based, privately held defense technology company founded in 2022 with 51–200 employees. It designs modular unmanned aerial systems, including small UAS platforms, and integrates mission payloads aimed at military and special operations users. The company also develops a deployable microfactory concept, xCell, using additive manufacturing to produce systems closer to the point of need. Its stack spans embedded hardware (ARM Cortex-M, Embedded Linux, RTOS), web tooling (TypeScript, React, GraphQL), and cloud infrastructure on AWS and Kubernetes. Hiring is concentrated in the United States, with additional activity in Peru.
Firestorm uses C++, Rust, Python, ARM Cortex-M, RTOS, Embedded Linux and CAN-FD for embedded systems, plus TypeScript, React, GraphQL, Prisma, Kubernetes and AWS, with Arena PLM and QGroundControl.
Yes. Hiring is accelerating and engineering dominates open roles, skewed toward senior and staff levels, with additional openings in manufacturing, operations and sales.
