Backend Engineer

Who We Are

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.

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 plans and executes production across factories that don't look alike, using supply that isn't guaranteed to arrive. It runs in the cloud, inside a factory, and air-gapped in classified environments, with consistent behavior across all three.

The backend has to represent how production actually works: materials, inventory, resources, processes, work, constraints, and the state of a factory as it changes. It has to integrate with systems that own different pieces of that truth, support planning and optimization, and remain correct across deployments that may lose connectivity for hours or days.

We are hiring a Staff Backend Software Engineer to help build the core backend of Crucible. The backend is heavily Type Script today, with GraphQL and Prisma, but we expect the stack to evolve with the product.

• Build Crucible's backend — Design and ship the services, APIs, data models, and workflows behind production planning and execution.
• Own core system models — Define how Crucible represents production, materials, inventory, resources, work, and operational state.
• Design for distributed operation — Build systems that behave correctly across cloud, factory, and disconnected deployments, including synchronization, reconciliation, and failure recovery.
• Build durable integrations — Connect Crucible to PLM, ERP, quality, test, optimization, and other production systems through clear interfaces and ownership boundaries.
• Make the system reliable — Improve performance, observability, testing, and failure handling for software used to run real production.
• Partner on architecture — Work with software leadership and architecture on service boundaries, data ownership, system interfaces, and technical direction.
• Raise the engineering bar — Review critical code and designs, improve development practices, and help other engineers solve difficult backend problem
