Software Engineer

This fast-growing stealth defense technology startup is building an AI-native platform designed to automate complex operational and administrative workflows for mission-critical military organizations. By combining organizational data, knowledge graphs, LLM-powered agents, and workflow automation, the company is helping users replace highly manual processes with intelligent, scalable systems. Backed by $2.5M+ in pre-seed funding from leading enterprise software and defense-tech investors, the company is already deployed with multiple Department of Defense customers and has approximately $270K in ARR, with significant growth expected as additional contracts launch. The team was also recently selected for a 7-figure Air Force R&D contract. This is an opportunity to join a small founding team at a key inflection point, take meaningful ownership of the product, and help shape both the technology and engineering culture as the company scales.
