Founding Software Engineer

We're recruiting for a seed-stage startup in Los Angeles that is industrializing advanced composite materials for defense and aerospace customers. They combine AI software, robotics and their own manufacturing, and they're hiring 3 to 4 founding software engineers to build the core operating system for the factory from scratch. No legacy code, no ticket queue. The software is the moat here, not an internal tool bolted on later. What you'll work onThe factory operating system: supply chain, quoting, pricing, inventory and operational flow, from raw material to finished part A simulation layer that trains models on factory floor data to predict how parts behave in the real world Factory automation: ingesting real-time telemetry from equipment, orchestrating robotics and running a 24/7 digital twin of the line Backend systems and data models that mirror the physical world (think Palantir-style ontology for a factory) What they're looking for 2+ years shipping production software as a full-stack or product engineer. TypeScript on the frontend, Python or Go on the backend. Full-stack is a must. Real startup experience. You've owned things end to end at a fast-moving startup, not just worked tickets at big tech. You figure out what to build, not only how. You're comfortable with ambiguity and set your own goals. Strong opinions on data modeling in early-stage systems Must meet ITAR requirements (US citizen or green card holder). No visa sponsorship. On-site 5 days a week in Los Angeles. Relocation support available. Big plus Manufacturing software, ERP or MES experience, or any time around hardware and factories Data engineering, CAD, computational geometry, 3D or simulation work Time at companies like Anduril, Palantir, Ramp, Stripe or Hadrian, or a side project that actually went somewhere Why it's worth a look Pay is above LA market, plus meaningful founding equity (0.2% to 1.0%)Well funded, with real defense and drone customers and demand already lined upTechnical founders who still write production code Meals covered and a budget for whatever tools make you faster
