Systems Software Engineer, Linux/Edge

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.Are you ready to apply Make sure you understand all the responsibilities and tasks associated with this role before proceeding.Who We AreAt 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 at scale. Firestorm 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.About the RoleFirestorm 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.What You'll DoBuild 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 Qualifications8+ years building systems, platform, infrastructure, or embedded Linux softwareU.S. person required due to ITAR regulationsDeep Linux experience, including processes, networking, filesystems, service management, and system debuggingStrong proficiency in at least one systems programming languageExperience building and operating software on physical or edge computeStrong networking fundamentalsExperience with provisioning, configuration management, software updates, or device lifecycle managementExperience integrating software with hardware, peripherals, or external devicesDemonstrated ability to debug problems across software, operating system, network, and hardware boundariesPreferred QualificationsExperience with Rust, C++, Go, or PythonExperience with containers and edge orchestrationExperience with air-gapped or intermittently connected systemsExperience with Linux image creation, boot processes, systemd, kernel configuration, or device driversExperience with industrial protocols such as OPC UA, MQTT, Modbus, serial, or CANExperience integrating industrial equipment, test systems, printers, scanners, or factory automationExperience with secure boot, device identity, disk encryption, or hardening Linux systemsAerospace, defense, robotics, industrial automation, or manufacturing experienceWork EnvironmentThis 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.CompensationUS Salary Range: $175,000 – $220,000 USDThe posted salary range reflects an estimate based on a variety of compensation factors, including but not limited to relevant experience, education, certifications, specialized skills, geographic location, and business needs.
