About the Role

Firestorm builds uncrewed aircraft and the manufacturing network that produces them: full-capability plants, deployable xCell edge factories, and forward-deployed sites that stand up production near the point of need.

Crucible is the software that runs that network. It runs in the cloud, inside a factory, and air-gapped in classified environments. At the edge, Crucible has to operate reliably on local compute, connect to factory equipment, and keep working when cloud infrastructure and internet connectivity are unavailable.

We are hiring a Staff Software Engineer to build the systems layer behind Crucible's edge deployments. You'll own the Linux environment, deployment and lifecycle infrastructure, and the interfaces between Crucible and the machines, workstations, printers, test equipment, and other systems on the factory floor.

What You'll Do

• Build Crucible's edge platform - Design the runtime and infrastructure that runs Crucible in factories, xCells, and air-gapped environments.
• Own the Linux environment - Define how systems are configured, provisioned, networked, secured, updated, and recovered.
• Connect the factory floor - Build interfaces to machines, workstations, printers, scanners, test equipment, and other production hardware.
• Build for disconnected operation - Make edge systems reliable through network loss, degraded connectivity, restart, and recovery.
• Own device lifecycle - Build tooling for provisioning, configuration, software updates, diagnostics, and fleet management.
• Debug the full system - Troubleshoot problems across applications, Linux, networking, peripherals, and physical equipment.
• Partner on architecture - Work with software leadership and architecture on edge-to-cloud interfaces, deployment topology, security, and system boundaries.

Required Qualifications

• U.S. Citizenship and ability to obtain and maintain a U.S. Government security clearance
• 8+ years building systems, platform, infrastructure, or embedded Linux software
• Deep Linux experience, including processes, networking, filesystems, service management, and system debugging
• Strong proficiency in at least one systems programming language
• Experience building and operating software on physical or edge compute
• Strong networking fundamentals
• Experience with provisioning, configuration management, software updates, or device lifecycle management
• Experience integrating software with hardware, peripherals, or external devices
• Demonstrated ability to debug problems across software, operating system, network, and hardware boundaries

Preferred Qualifications

• Experience with Rust, C++, Go, or Python
• Experience with containers and edge orchestration
• Experience with air-gapped or intermittently connected systems
• Experience with Linux image creation, boot processes, systemd, kernel configuration, or device drivers
• Experience with industrial protocols such as OPC UA, MQTT, Modbus, serial, or CAN
• Experience integrating industrial equipment, test systems, printers, scanners, or factory automation
• Experience with secure boot, device identity, disk encryption, or hardening Linux systems
• Aerospace, defense, robotics, industrial automation, or manufacturing experience

Work Environment

• This role is based in San Diego, CA.
• We welcome candidates who are local or open to relocating; relocation assistance is available and may be included in the offer package where appropriate.
