Job description

About Ironflow AI About Ironflow AI Our mission is simple: to build software to help people build extraordinary things. We are building an AI-native ERP for aerospace, defense, and advanced manufacturing. Purchasing, inventory, planning, manufacturing, finance, and accounting: the core systems that determine whether companies can actually build and deliver. Much of the industrial base still runs on software architectures designed decades ago. We think that is now a strategic problem. Our mission is bigger than better software. If the United States and its allies need to build more ships, aircraft, missiles, drones, engines, satellites, and everything behind them, the companies doing that work need radically better systems. We are building Ironflow around five values that define how we work: hard work, excellence, kindness, creativity, and teamwork. We put in the effort and follow through. We take pride in our work and keep raising the bar. We treat people with care and respect. We explore possibilities and find better ways. And we help each other succeed while taking responsibility for the shared outcome. We are veterans, engineers, and operators who have lived the limitations of legacy systems firsthand. We are building the software we wish existed. Why This Role Matters As a backend engineer, you’ll help shape the core logic that powers real-time, intelligent workflows across manufacturing, inventory, and supply chain. Your work will unlock faster decisions, tighter coordination, and adaptive operations for the people driving the defense tech revolution. What You’ll Own Architecting and implementing backend services in Python with PostgreSQL Designing and exposing GraphQL APIs to support AI agents and real-time frontends Building secure, scalable models for production, procurement, and inventory Optimizing database performance and ensuring system reliability at scale Contributing to CI/CD pipelines, Docker-based environments, and deployment workflows Enabling real-time orchestration across human and AI agents What You Bring 5+ years of backend or full-stack experience with production systems Mastery of Python, FastAPI, PostgreSQL, and GraphQL Experience designing modern APIs with GraphQL A track record of owning features end to end — from design to deployment Comfort with ambiguity, fast iteration, and cross-disciplinary problem-solving Bonus: Familiarity with FedRAMP, ITAR/DFARS, and secure multi-tenant architectures Bonus: Experience with WebSockets, real-time systems, and frontend debugging in React How We Work Everyone at Ironflow moves fast, solves real problems, and holds a high bar for craft. We expect you to lead, not just follow, and to build systems that stand up to real-world complexity while staying clean and maintainable.
